There are multiple causes for the user to see this error code, including if a user is using volume-licensed media while installing a number of various Windows operating systems. This error may also be caused because the activation wizard cannot connect to a KMS host computer. It is likely that if the user has a volume-licensed form of media, they were likely given a MAK (multiple activation keys).

Further Information and Manual Repair

There are several ways to go about repairing error code 0x8007007b. It is important to try all of the methods, but if it is too difficult or you do not know what you are doing, please do contact a Windows repair technician. They will likely be able to fix the problem with ease.

Method One: Instead of KMS activation, use a Multiple Key Activation

When KMS activation is not used, and when there is not a KMS server, the product key type should then be changed to a MAK. For MSDN (Microsoft Developer Network) or TechNet, the SKUs that are listed on the media are generally volume-licensed media, and that means that the product key that is supplied is a Multiple Activation Key.

To change the KMS to a MAK, click Start, All Programs, Accessories, and then right-click on Command Prompt. Click Run as Administrator. If prompted for a password or confirmation, enter it now.

When the command prompt opens, type in the following command, and press enter after:

slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx (these x's are representative of the MAK product key).

Method Two

While on the desktop, press the Windows key and R. The Run window should appear, and then you should enter the following command: Slui 3. Press Enter and then wait for the window to appear. This window will ask for the operating system activation product key. Enter the product key and then press the Activate button. Reboot the computer. Now the Error Code 0x8007007b should be gone.

Method Three

Open the Command Prompt with access as administrator as mentioned previously. Enter the following command: sfc /scannow. The command will then complete its task. This will take a good bit of time, so leave the computer to do its work. The sfc must finish the scan. When the scan has finished, reboot the computer. Now you can check for activation. The error code should be gone.

Method Four: When the client can't locate a KMS host on the network to complete activation

This method for correction should be used when the network does have a KMS host computer setup, and the client is not able to locate the KMS host on the network to complete activation.

To verify that the computer does in fact have the KMS host installed. Click Start, All Programs, Accessories, and then right-click on Command Prompt. Run as administrator. If you are now prompted to enter a password or confirmation, do so. When the command prompt box comes up, type in the following command, and then press Enter: nxlookup -type=all_vlmcs._tcp>kms.txt

The command will generate a file, open this KMS file. The file will contain one or more entries. As a default, the KMS host server will dynamically register a DNS SRV server evidence once every 24 hours. In order to check the registry to ensure that this is happening, follow these steps:

  • Click Start, type in regedit, and then press Enter.
  • Locate the key HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionSL and then click on it.
  • The DisableDnsPublishing subkey should be present and have a value of 1. If it is missing, create a DWORD value by right clicking DisableDnsPublishing, click Modify, in the Value Data box type in 0, and then click Okay.

2 Proven Methods to Fix Regsvr32 Error

What is Regsvr32 Error? - What Is It?

Regsvr32 is basically a command-line utility.

This command is used to register and unregister OLE controls for example the digital link library files and ActiveX controls in the Windows Registry. This command appears as the Regsvr32.exe file and is installed in the Microsoft Windows system file in the %systemroot%System32 folder.

The Regsvr32 command loads the library and tries to call the DllRegister Server and DllUnregister Server. In other words, it helps to register COM-based digital link library files to run different programs on your PC.

However, when the Regsvr32.exe file gets corrupt, you get the Regsvr32 to troubleshoot the error message on your computer screen. It can be displayed in various ways including the following:

“To register a module, you must provide a binary name.”

Error Causes

Generally, Regsvr32.exe becomes corrupt because either the load library, DllRegister Server or DllUnregister Server function fails. This indicates that the dll specified path was missing, incorrect, or couldn’t be found.

Here’s how the error messages are often displayed while registering a dll using Regsvr32.exe:

  • “The command-flag "%1" is not valid. Please review the command usage and try again.”

If this error message is displayed, it typically means that you entered an invalid combination of command-line arguments or switches when calling upon the Regsvr32.exe application.

  • “To register a module, you must provide a binary name.”

The cause of this error message is that you called the Regsvr32.exe function with no modules to register located in the command line arguments.

  • “The module "%1" failed to load.nn Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files.nn%2.”
This Regsvr32 error message indicates that Windows had problems with loading the modules that you have identified in the command line.

Further Information and Manual Repair

Here are 2 recommended solutions to fix the Regsvr32 error on your PC:
  1. Re-run the command

    You must re-run the Regsvr32 command from an elevated command prompt. For this, go to the start menu and type Command Prompt in the search box.

    Now right-click the Command Prompt and click the option that says Run as Administrator to run the command on your PC. If it prompts you to enter an administrator password, type the password and then click Allow to run the command.

  2. Register a 32-bit Dll using a 32-bit version of Regsvr32 on a 64-bit version of Windows

    This may sound tricky but it is even simpler than the first solution discussed above. To register a 32-bit DLL using a 32-bit version of Regsvr32 on a 64-bit version of Windows, open an elevated command prompt.

    After it’s opened, if you see the 32-bit DLL is located in the following path: %systemroot%System32 folder, move it to %systemroot%SysWoW64 folder. Once you change paths, run this command: %systemroot%SysWoW64regsvr32 <full path of the DLL>

Try following these 2 recommended solutions to immediately fix and repair this error on your computer.

The solutions should eliminate the occurrence of error messages such as “To register a module, you must provide a binary name.” It is so easy and effective and you can do it on your own without calling over a professional.

Problem prevented document from being scanned
If an error suddenly pops up that states, “A problem prevented the document from being scanned” when you’re scanning a document in your computer, then you’ve come to the right place as this post will guide you on how exactly you can fix the problem. A lot of users have reported that they receive a two-layer error message when they try to scan their documents – the first screen throws an error message that says, “Error applying Settings to Driver” while the next error message states, “A problem prevented the document from being scanned”. As a result, the scanning won’t be completed which defeats the whole process of buying a printer with a scanner. As you can see the two error messages point to two different situations, while the other one is pointing at the driver, the second one points to the scanning problem. To resolve these issues, there are several suggestions you need to check such as follows:

Option 1 – Run the Printer Troubleshooter

One of the first basic troubleshooting you can perform to resolve the printer issue is running the Printer Troubleshooter. This built-in troubleshooter can detect and automatically fix the problem for you. To use it, follow these steps:
  • Tap the Win + R keys to open the Run dialog box.
  • Next, type “msdt.exe /id PrinterDiagnostic” in the field and click OK or hit Enter to open the Printer Troubleshooter.
  • Then click the Next button and follow the next on-screen instructions to fix the issue with the printer.

Option 2 – Try updating the Printer drivers

You might also want to try updating your printer drivers. All you have to do is locate the USB Composite Device. For complete details, follow the steps below.
  • First, click the Start button and type “device manager”.
  • Then click on the “Device Manager” from the search results to open it.
  • From there, look for the USB Composite Device option and right-click on it, and select the Update Driver from the options.
  • Restart your PC and then click the “Search automatically for updated driver software” option.
Note: You also have the option to download the latest version of your Printer from the manufacturer’s website.

Option 3 – Try to reset the settings of the Printer or reinstall it

If none of the two options given above worked, you can try to either reset the printer settings or reinstall the printer so that it can go back to its default state. However, if it doesn’t work, you can try to uninstall the printer as well as its related drivers. To do so, follow these steps:
  • First, go to Settings > Devices > Printer and Scanners.
  • After that, select the printer and select the Remove Device option.
  • Once done, restart your computer and check again and see if the error is now fixed.

Option 4 – Try to modify the Registry settings for the Still Image devices

In case you don’t know, Windows has Registry settings for the Still Image devices like Scanners and Printers. And these devices have vendor-specific settings that if ended up getting corrupted or misconfigured then you will most likely encounter errors like “A problem prevented the document from being scanned”. Thus, to fix this error, you can try modifying the Still Image devices registry settings, and to do that, you need to follow the instructions below but before that, make sure that you create a System Restore Point first.
  • Once you’ve created a System Restore point, tap the Win + R keys to open the Run dialog box and type “Regedit” in the field, and then hit Enter to open the Registry Editor.
  • Next, navigate to this registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStillImage
  • From there, right-click on the “StillImage” registry key and delete it.
  • After that, exit the Registry Editor and restart your computer.
  • Once your computer has restarted, Windows will recreate the settings of the Still Image devices back to their default settings.

To simply put it, it will enhance the graphics of the virtual machine and will let you use 3D graphics. Although it may seem nice, it can actually cause the black screen to appear as well so you might have to disable it to isolate the problem.

It can also appear when other major pieces of hardware, like the motherboard, have been changed out.  These pieces may be changed as part of an upgrade to new or better hardware or be changed due to the malfunction of the original pieces of equipment. Because it may appear to the Windows activation servers that you are attempting to use the same product code that you have used before to activate what appears to be a new machine (even if the machine is the same one, just with some new parts), you may see Error Code 0xC004F00F arise.

Error Code 0xC004F00F can also come up if you have installed Windows 10 on your machine in the past and have already used the product key that you are attempting to use again.

Further Information and Manual Repair

Error Code 0xC004F00F most commonly appears for users who have made major hardware or software changes done on their machine. Because this error specifically arises from the Windows activation servers believing that your computer is a new one, you’ll need to get in touch with the Windows support team in order to resolve the error. From their database, they will be able to confirm that you are not using a new computer and will be able to bypass the error, allowing you to complete the Windows 10 Activation process.

If you haven’t installed or replaced any of the hardware on the computer, but are still seeing Error Code 0xC004F00F arise during your Windows 10 installation, you will still need to get in touch with the Windows support team to bypass the error code.

Calling the Windows' Support Team

When you call into the Windows support team, you’ll want to specifically have a list of the following information readily available: Which pieces of hardware have been changed out on your computer prior to the installation and activation, what method you were using to install Windows 10, which version of Windows 10 that you were attempting to install, whether it was a single-use or multiple-use license, and basic details about your PC like its make, model, and age.  You may also want to have the product key that you were attempting to use when Error Code 0xC004F00F first appeared.

By having all of this information ready and on hand ahead of time, you’ll have a greater likelihood that your error will be able to be resolved quickly and efficiently, avoiding long periods spent on the phone with customer service. Make sure that you specifically mention that you are experiencing Error Code 0xC004F00F during the Windows 10 activation process when you call into the Windows support team so that you can be connected to a representative who is equipped to help you resolve this specific problem.

Getting a Qualified Technician

If you are not comfortable in working with the Windows support team or have not been able to successfully resolve Error Code 0xC004F00F even after getting in touch with customer support, contact a qualified technician who is familiar with the Windows 10 activation process and can walk you through the things that you will need to communicate to the Windows support team in order to have them bypass or resolve the error code.

Intel i9 Alder Lake better than AMD Ryzen 9
Alder LakeIf we are to believe news from Intel, new series of processors based on Alder Lake architecture are about to be released somewhere in October. Alder Lake is the 12th Generation Core of Intel processors and it is meant to have all advantages of the current CPU structure. I9 is aimed to pack a punch against its competitors with technology including eight high-performance Golden Cove cores (P-cores) with Hyper-Threading and eight energy-efficient Goldmont (E-cores) equipped with a 30MB L3 cache and operating at high clock speeds. During the benchmark test, the new CPU outperformed all of Intel’s previous Rocket Lake structure processors which is logically expected but the big surprise came from results that indicate better performance than Apple’s new M1 processor even in single-threaded performance which is supposed to be best in that field. Another surprise was really beating AMD Ryzen 9 in each field. If we take into account that i9 has 16 cores in total and can process 24 threads against Ryzen 9 with 16 Cores and 32 threads this is an impressive feature. Now truth to be told Alder lake has massive L3 cache and microarchitectural advantages and consumes much more power but the results of performance are high. Also, note that this early CPU is not really a mass production one and maybe some things will still change but early results are very satisfactory. We will see what will price tag be since in this age of shortage and competition that will also play a big role in its overall success. Speaking of competition I eagerly await AMD’s response to this, in any way it seems that the CPU market is for some turbulence which is always a good thing for the final customer and I welcome it.

Fix Black background behind Folder icons
The File Explorer in Windows 10 provides several ways to organize the contents of folders and files in the system. Windows users can utilize some efficient styles to view the contents of the file system as per the user’s requirement. A user may opt to display the file picture in large size thumbnails while the other one could opt to set the icons of folder and files in a small or medium size list. On the other hand, while setting up several styles for the folder and file icons, some Windows 10 users have experienced some unusual issues where there is the Black background showing up behind folder icons. They tried refreshing the File Explorer a couple of times but it didn’t help in fixing the problem and the black squares are still visible on some folder icons. The black squares behind the folder icons might look disturbing though it’s not really a big problem and is merely a graphical glitch that does not cause any damage or whatsoever to the content of the folder and files. The most likely cause of this glitch might have something to do with the corrupted system files or it could also be caused by outdated thumbnail caches.
