However, if you don’t feel like you will be able to perform the necessary steps on your own, be sure to get in touch with a qualified computer repair technician to help you in the resolution of this particular error.

Solution

Error Causes

Two things are generally behind the appearance of Error Code 0x80072efe on a Windows device. The first is that one or more of your registry keys are not available, have been corrupted, or are not installed properly. The second is that necessary DLL files aren’t working properly within your machine.

However, other things can mimic these causes, which is why the two methods listed below will resolve the issue in most cases.

Further Information and Manual Repair

Fortunately, there are two resolution methods that can be used quickly and easily when Error Code 0x80072efe arises on your Windows computer. Neither of these requires advanced knowledge or skill, but if you don’t feel comfortable with performing these steps on your own, it is recommended that you contact a qualified computer repair technician in order to get assistance.

Here are the best ways to resolve Error Code 0x80072efe on your computer:

Method One:  Check Your Time and Date Settings for Accuracy

If your time or date has been set incorrectly, it can make your system logs appear to have incorrect information, which can lead to the appearance of Error Code 0x80072efe. Because this is the easiest thing to fix if it is indeed the problem that is making the error code appear, this should always be the first thing that you try when this error code arises.

In order to check your time and date settings, follow these simple steps:

• Step One: Make sure that you are logged into your computer as an administrator.
• Step Two: Click on the time and date listed on the lower right edge of your screen. If the settings are not correct, choose the option to change the time and date.

If method one has not successfully resolved Error Code 0x80072efe, you may need to attempt method two.

Method Two:  Check Your Firewall Settings During Updates

In some cases, your firewall can prevent your machine from accessing the information that it needs in order for the installation or update to go through correctly. If that is the case, you can follow a few simple steps to turn off your firewall, just while you install the update, and then turn it back on.

In order to do so, follow these steps:

• Step One: In the Start menu, choose the option to open the Control Panel.
• Step Two: Select the option for System and Security, looking for and clicking on Windows Firewall.
• Step Three: Turn off any private network firewalls.
• Step Four: Reboot your computer to apply the changes that you have made.
• Step Five: Re-attempt to run your Windows Update.

Note that if this method allows you to successfully bypass the error code, you’ll need to make sure to turn the firewall back on when you are finished. Even though it can interfere with the Update process, your firewall is still very important to your computer.

Method Three: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

Windows 10 has a lot of several useful features and one of them is the Nearby Sharing feature. You can access this feature by going to Start > Settings > System > Shared experiences. From there, switch on the Nearby Sharing option and select the folder where you want to download the files to. This feature is really useful as it allows you to share files. However, there were reports from a number of users recently stating that Nearby Sharing is not working on their Windows 10 computers. If you are one of the users facing this problem, you might want to try checking if the Windows 10 v1803 Update is installed on your computer or not. You could also try to check if Bluetooth supports low energy mode or you could also try bringing the device closer or check if the adapter has Bluetooth version 4.0 or later. For more information, refer to each one of the given options below.

Option 1 – Try checking if Windows 10 v1803 Update is installed

To check if the Windows 10 v1803 Update is installed on your computer, go to Start > Settings > System > About. From there, scroll down to the Windows specifications and check the Version. If it is 1803 or above, then the Nearby Sharing feature should be active on your computer. However, if you find that Windows 10 v1803 Update is not installed yet, then you need to update your computer to its latest version and then see if it fixes the problem or not.

Option 2 – Verify if Bluetooth supports low energy mode

Although low energy mode is not really necessary in using Nearby Sharing, there are some Bluetooth terminals that support low energy mode which makes a lot of difference. Thus, you need to check if Bluetooth in your computer supports low energy mode by following these steps:

• Tap the Win + R keys to open the Run dialog box.
• Next, type “devmgmt.msc” in the field and tap Enter to open the Device Manager.
• After that, expand the list of Bluetooth adapters, and then right-click on your adapter and select Properties.
• Go to the Details tab and select Bluetooth radio supports Low Energy Central Role from the drop-down menu and if its value says “<true>”, it means that your Bluetooth supports low energy mode, otherwise, it doesn’t.
• If your Bluetooth does not support low energy mode, then you might want to consider purchasing an external one.

Option 3 – Try bringing the devices closer

Nearby Sharing might not work if your devices are not close enough. Thus, you need to bring your devices closer together and see if it fixes the problem. And when you do, make sure that Network Sharing is switched on for all the concerned devices.

Option 4 – Make sure that you’re using Bluetooth version 4.0 or later

For you to use the Nearby Sharing feature, you have to make sure that the adapter for all the concerned devices is using Bluetooth version 4.0 or later. So if one of the devices or if all the devices are not using this version or later versions, then you must buy an external Bluetooth adapter for you to enjoy the Nearby Sharing feature.

3. Windows Resource Protection found corrupt files but was unable to fix some of them.

If Error Code 0xc00000e9 appears on your screen, there is no cause to panic yet as there are different ways to fix this. Here, I will list down different methods to get your computer back on track:

1. Check peripheral connections
2. Check your SATA cables
3. Check your hard drive
4. Check your BIOS settings

Quick Fix 1. Check Peripheral Connections

1. Turn off your computer.
2. After the computer has been shut down, take off all the peripherals or the USB cables that are connected to your USB ports. This includes even the keyboard and the mouse. We just need to have only the monitor plugged in for this one.
3. Turn on your computer and see if it starts as it normally does.
4. If it does, try connecting back your external devices or peripherals one by one until you find the one that causes the error.
5. Once you trace the device that’s causing the error, you will have to change its USB cable and update its driver to support your operating system.

Quick Fix 2. Check your SATA cables

It is possible that what causes a barrier between your operating system and your hard drive from communicating is the SATA cable used. For example, if you’re using an older SATA with a SATA III port, there might not be adequate support for the transfer of data from one another. Or, the problem might be a loose SATA cable which would still require you to buy a new one to replace your loose or damaged cable. To check if your SATA cables are causing the error, simply follow these steps:

1. Turn off your computer.
2. Carefully open its case.
3. Check the hard drive and the SATA port where it’s connected.
4. Try to use a newer cable and connect it to your SATA port. (If you used a SATA II cable, you can see if a SATA III cable is more compatible.)
5. Replace your SATA cable with a newer one if Step 4 proves to be successful.

Quick Fix 3. Check your hard drive.

1. Try to use a different hard drive and see if error code 0xc00000e9 still appears.
2. If it works out just fine, then the problem might be physical damage to your hard drive and would need to be repaired depending on the case. Just simply take it to a technician and let him know about the issue.

Quick Fix 4. Check your BIOS settings

1. Restart your computer.
2. Once your computer starts, press and hold the ESC, F2, F12, or DEL key to go to BIOS settings.
3. You will then be redirected to the BIOS Setup Utility screen. From here, go to Boot options.
4. In the Boot Options, see if your first boot device is your hard drive. If it isn’t, press the arrow key to select the hard drive and move it to the top of the boot device list.
5. Save the settings.
6. Reboot your computer.

Note: If all the methods above do not work, the problem might be on your drivers and you might need to update them. You can update your driver in two ways: Manual driver update and Automatic driver update. You can find procedures online in updating your drivers.

It has been some time since the release of Diablo 2 resurrected and overall reception was pretty good. People are enjoying the old classic game in hi-def. resolution and with new and improved visuals. Sadly some server issues are present still until this day and somewhat spoil the experience for players. The greatest lag and server crashes are pinpointed to game-creating events. When a player creates a new online game, the server needs to pull a lot of details from the database and make a game, due to some legacy code present this process takes some time and it is demanding a bit on the server-side, and although code was optimized to cater to more modern approach some legacy code still remains. Another thing that was spotted to affect performance itself is player behavior, to be more specific, modern gamer behavior. Where players find good builds and runs on the internet and then go to farm-specific areas or bosses for loot or experience points, which in return boils down to making plenty and short runs that are made by creating games and after run eliminating them. Now pair that with the previous statement about legacy server and database code and you can add 1 and 1 and see how this might be an issue. A lot of short games over legacy code are placing games in a state it was not designed for back in 2001 and therefore we have issues. Sadly solutions without completely rewriting the whole code are not very promising and they include rate limiting, which will prevent players to create many games in succession in a short period of time and maybe even login queues to drop a load on servers. Blizzard reached to people in the whole company, even old diablo 2 developers to ask for advice and they say that they are working on solutions so they could lift limitations and have everything running fine.

In case you don’t know, when you visit a website that uses HTTPS, it also offers an SSL certificate to the browser in order to verify the website’s identity. Although it may contain lots of things inside it, one of them is the URL of the website. So if the certificate does not match the URL to what you entered, you will most likely get the “Server’s certificate does not match, ERR CERT COMMON NAME INVALID” error which indicates that the connection is not private and the site may try to steal your data but worry not, as this post will guide you in resolving this issue. To fix the ERR_CERT_COMMON_NAME_INVALID error, here are some suggestions that might help.

Option 1 – Check the website’s certificate

If you own the website where you’re getting the error, then you might have to check if the website’s certificate is installed properly and configured on the server as it could be the reason why you’re suddenly getting the error.

Option 2 – Check the Windows Host file

You can also try to cross-check the Windows Hosts file to find out if the website you are trying to open has been blocked, because if it is, then it’s no wonder why you’re getting the ERR_CERT_COMMON_NAME_INVALID error. There are instances when some third-party application modifies the file and adds some websites to the blocklists. So if the website is indeed blocked, you need to remove it from the list.

Option 3 – Use the Google Public DNS

You might want to change your DNS to Google Public DNS as it could also help you in fixing the ERR_CERT_COMMON_NAME_INVALID error in Chrome. To do so, follow the steps below.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 4 – Run the built-in Malware Scanner and Cleanup Tool in Chrome

In case you don’t know, there is actually a built-in malware scanner and cleanup tool in Chrome that helps you get rid of any unwanted ads, pop-ups, and even malware, as well as unusual startup pages, toolbars, and other things that could affect the performance of the browser. In addition, this built-in tool in Chrome might also help in fixing the ERR_CERT_COMMON_NAME_INVALID error.

Option 5 – Reset Chrome

Resetting Chrome can also help you get rid of the error. Resetting Chrome means restoring its default settings, disabling all the extensions, add-ons, and themes. Aside from that, the content settings will be reset as well and the cookies, cache, and site data will also be deleted. To reset Chrome, here’s what you have to do:

• Open Google Chrome, then tap the Alt + F keys.
• After that, click on Settings.
• Next, scroll down until you see the Advanced option, once you see it, click on it.
• After clicking the Advanced option, go to the “Restore and clean up option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
• Now restart Google Chrome.

The “Unknown Hard” error that keeps on appearing in Windows 10 can put users in an unpleasant situation. This kind of error leads to the freezing of the taskbar, blackening of the screen, and sudden disappearance of the icons on the Desktop. And each time you try to open Windows, the system will only give you an error message saying that it’s a critical error and some applications like Start and Cortana won’t work. Upon analysis, it seems that the “sihost.exe” is not responding and that it is the one that’s causing the c000021a Unknown Hard error to pop up. Sihost.exe files represent the Shell Infrastructure Host which is an essential component in the Windows operating system. The Windows Shell Infrastructure Host is primarily responsible for handling some graphical elements of the operating system interface such as the Start menu and the taskbar transparency. And so if the Shell Infrastructure or Sihost.exe has stopped, has been removed, or corrupted, you will most likely have issues with the overall functionality of the Windows operating system and you’ll get the Unknown Hard error In addition, the ctfmom.exe Unknown Hard error may also occur due to incompatible drivers installed on your PC. Ctfmom is a process that identifies inputs such as handwriting, languages, and many more. It’s the one that controls the functions of background behavior. To resolve this issue, you need to first try to identify which application is the one that’s running the sihost.exe file. And if needed, you need to either update or reinstall or completely uninstall the problematic application.

Option 1 – Try to run the System File Checker

The SFC Scan or System File Checker, us a built-in utility in Microsoft Windows that can be found in the C:\Windows\System32 folder. This tool allows users to scan and restore any corrupted system files in Windows that might be causing the Unknown Hard error to appear. Before you use this tool, make sure to find out whether the sihost.exe on your computer is a Trojan that you have to remove or if it’s a file that belongs to a trusted Windows application. Once you have that sorted out, follow the steps below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 2 – Try to use System Restore

You can also try using System Restore. This is one of the ways you can use it to back up your PC. Since restore points are created automatically each week by System Restore, you can use System Restore to restore your computer back to an earlier good point in time.

Option 3 – Try to troubleshoot the error in a Clean Boot State

Putting your PC in a Clean Boot state can help you diagnose and troubleshoot the issues in your system. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the Unknown Hard Error.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” checkbox.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)

After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

• From the “Start” menu, go to System Configuration.
• After that, switch to the General tab and click the option for “Normal Startup”.
• Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
• Then find and click “Enable all” and if prompted, you have to confirm.
• Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
• Restart your PC when prompted.

DOTA2 involves teams of five players each, where each player chooses a “hero” character. Each game has two teams pitted against each other, on opposite sides of a map. Once you start, you and your teammates try to level up by fighting and defeating heroes from other teams as well as non-player characters who exist within the game universe. Once you have a strong enough team, you would then try to attack an opposing team’s base. If you destroy their “ancient,” your team wins. The teamwork and interactivity required to play the game are some of its biggest attractions. You can text and voice chat as part of the Dota 2 gameplay, enabling you and your team to come up with strategies to take over your opponents’ base and fortifications. For this reason, a properly working microphone and headset are important if you are to get the most out of this exciting online game. However, there are many times when you find that there are audio dropouts when you try to speak into your microphone. The question “How do I get my mic to work on Dota 2?” is one of the most commonly asked on gaming forums related to this game. Here are solutions for why this can happen:

1. You are logged in to another computer that is running the STEAM client

   While entirely rare, there are cases where the microphone in Steam is disabled because the same account is active and in use on a different computer. It may not notify you that your account is in use elsewhere. If this is the error, try to log out on other devices and then test it on only one system. If you cannot access the other computer that has access to your account, then change your password. This will automatically disconnect your Steam account from the other computer and let you enjoy voice chat in Dota 2 and other Steam games.

2. Your microphone is not properly set up in Dota 2

   From the main Dota 2 menu, before you start a match, you can set up your microphone for voice chat. At the top, left-hand corner, click the gear icon to open Settings Select the AUDIO tab and ensure that the Sound Device and Speaker Configuration are set to default. On the same tab, activate Voice (Party) and set your Push to Talk shortcut key for your team. Select the appropriate Open Mic Threshold using the slider at the bottom of this tab to get your microphone recorded at a comfortable level.

3. The Windows Audio Enhancements setting is turned on

   If you still cannot get your microphone to work properly, then your problem could be Windows Audio Enhancement. It is possible to get your microphone to work with Dota 2 by disabling these features. Right-click your volume icon on the system tray and select Recording Devices. Choose your active microphone then click its Properties button. On the Microphone Enhancements tab, make sure the checkboxes marked Voice enhancements and Acoustic Echo cancellation is unchecked Reboot your PC and retry using your microphone to chat.

4. Your audio drivers need to be updated

   If you try all of the steps above and still have Dota 2 not recognizing your mic input update mic drivers by going in device manager and choosing update driver.
