8: Replace the Hard Disk

If you are tried encrypting or decrypting a file using the default EFS engine but you receive an error message instead saying, “Error Applying Attributes, An error occurred applying attributes to the file: The specified file could not be decrypted”, read on as this post will help you sort out the problem. If you encounter this error you can use the error code in it. You will most likely get error code 0x80071771. This kind of error occurs when the File Explorer’s copy and paste feature was not able to read the source file being encrypted or decrypted. It could also occur if you try to access a file that has been on another computer previously.

To fix error code 0x80071771 when decrypting or encrypting a file, refer to the instructions provided below.

Step 1: You need to check first if you can decrypt the files encrypted by EFS. However, if you can’t, just proceed and then take full control of the file. Step 2: To take control of the file, open File Explorer and right-click on the partition, and then click on Properties. Step 3: After that, click on the Edit button under the Security tab. Step 4: Next, make sure that “Everyone” is selected under the Group or user names section. Step 5: Afterwards, the Permissions for Everyone section will be activated. Just make sure that all the checkboxes for Allow are checked and then click on the Apply button. Step 6: Once you’re done, click on the Advanced button. This will open a new window labeled Advanced Security Settings. From there, click on the Change link under the Owner section.

If you were trying to open File Explorer but it suddenly stopped working and you encounter an error message that states, “An attempt was made to reference a token that does not exist”, read on as this post will guide you in fixing this problem. This problem was initially reported after the April Update and Microsoft was able to fix it right after correcting the build. However, this effort seems futile for some users as recently, some reported getting the same error when they try to open not just Windows File Explorer but also with utilities like Microsoft Management Console or MMC, Visual Studio, Task Manager, Printer, Recycle Bin, etc. Two of the most likely causes of this error are a troublesome Windows Update and corrupted system files. Whatever the cause is, here are some suggestions you can follow to fix the “An attempt was made to reference a token that does not exist” error.

Option 1 – Try to re-register the problematic DLL file

You may have to re-register the ntdll.dll file using the regsvr32.exe before you can successfully install the program and fix the ntdll.dll file crash error. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
  • exe /[DLL file]
  • exe [DLL file]

Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.

• After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 2 – Replace the DLL file from a trusted source

• First, you need to get the new DLL file from another computer with preferably the same file version number.
• After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
  • x86: This PC > C:/Windows/System32
  • x64: This PC > C:/Windows/SysWOW64
• Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
• Now type the “regsvr32 ntdll.dll” command and hit Enter.
• Restart your PC and check if the error is now fixed.

Option 3 – Perform a System File Checker scan

The System File Checker or SFC scan could detect and automatically repair damaged system files that could be causing the “An attempt was made to reference a token that does not exist” error to pop up. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

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

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 4 – Try reverting back to the previous build of Windows

This kind of error might have something to do with a Feature Update so you can try to revert your computer to a previous build of Windows 10 as it could help you fix the problem. In this case, it would better if you refrain from updating your Windows 10 computer until this problem is completely resolved by Microsoft.

During Windows 10 installation, you will see all the beautiful user interfaces, however, what’s more, important are the drivers, your processor, and free storage disk in order for the installation to be successfully completed. So if you are getting the CompareExchange128 error during the installation of Windows 10, this means that the CPU lacks a very important instruction known as “CMPXCHG16B”. Thus, if you don’t have CMPXCHG16B, then it will result in the CompareExchange128 error when you install Windows 10. In fact, CMPXCHG16B, PrefetchW as well as LAHF/SAHF is a criterion for you to be able to use Windows 10 64-bit version when upgrading from an earlier version of Windows. So what exactly is the CMPXCHG16B instruction? The CMPXCHG16B instruction is the one that performs an atomic compare-and-exchange on 16-byte values. This instruction can also be referred to as “CompareExchange128”. The atomic compare-and-exchange means that the CPU compares the contents of a memory location with a given value. So if the values are the same, it modifies the contents of that memory location to a new given value. Note that this kind of issue only happens to the 64-bit Windows 10 version and the only way to resolve it is by getting an update on the hardware level from the OEM. On the other hand, if nothing really works, it’s maybe time for you to get a new CPU but before you resort to that, in the meantime, you can try following the options given below to fix the CompareExchange128 error during the installation of Windows 10.

Option 1 – Try to update the BIOS and Chipset Drivers

One of the best things you can do to fix the CompareExchange128 error is by updating the BIOS and chipset drivers which is why you need to check if your OEM has an update available for your computer’s BIOS as well as the related chipset drivers. But before that, you need to first check the BIOS version. To do so, follow these steps:

• Type “msinfo32” in the search bar and hit Enter to open the System Information Tools.
• After opening the System Information Tools, check the BIOS version.
• Then take note of that BIOS version. You also need to use the BIOS utility that came with your computer and use it for the upgrade. Note that it is different for every computer and if you don’t have it, you can just go to the OEM website and see if there is an option to download it there.

Option 2 – Try to downgrade to the 32-bit Windows 10 version

If option 1 didn’t work as the BIOS update is not available, you can also try downgrading to the 32-bit version of Windows 10. Keep in mind that this will bring restrictions on the amount of RAM installed and other places but that won’t be a problem as you can still switch.

Option 3 – Try buying a new hardware

If none of the first two options didn’t work for some reason then maybe it’s time for you to purchase new hardware especially if your computer is way too old. In such cases, it’s better to buy new hardware or better yet, a new computer that can keep up for the next couple of years.

VSSControl: 2147467259 Backup jobs failed. Cannot create a shadow copy of the volumes containing the writer’s data. VSS asynchronous operation is not completed. Code: [0x8004231f]

This message pops up when you are creating a snapshot system restore, usually, the issue is tied with insufficient space or service stopping. We will go into detail about how to fix both so you can finish the operation without any issue.

1. Check Volume Shadow Copy Services

   Easier and faster fix than the next one. Launch Services from the Start Menu, look for Volume Shadow Copy, double-click on it, and check the Service status. If it is stopped, click on the Start button. If it’s running, restart it by clicking Stop > Start.

2. Increase Shadow Storage Space

   If the first fix didn’t resolve the issue then you need to increase Shadow Storage Space. Launch Command Prompt as an administrator. Now, type the following command to check your Shadow Storage Space. vssadmin list shadowstorage Now, type the following command to allocate more storage (you can change 10GB with the amount of space you want to allocate) vssadmin resize shadowstorage /For=C: /On=C: /MaxSize=10GB

A command is not recognized Error, what it is? If you are constantly using programs like CMD or DISM directly from the Run prompt, you might have wondered how they launched instantly and how is it that the Windows operating system is able to find them right away. For instance, when you create a shortcut of a program, the shortcut knows where exactly the program is located and launches it quickly. The Windows operating system keeps a list of paths where the most common system programs are located so when you use the Run prompt, it opens easily. The list kept by Windows is called the Windows Environment Variables. If something goes wrong with this list, the programs won’t work. So in this guide, you will be guided on how you can troubleshoot the problem where any command you use is not recognized as an internal or external command, operable program, or batch file. Before you start troubleshooting the problem, you need to make sure that the program you are trying to run really exists. In fact, this can also happen to the Run program which is pulled up using the Win + R shortcut. To check, go to C:\Windows\System32 and there, check if the program exists or not or you can also try searching for the EXE in the System 32 folder. After making sure that the program exists, refer to the instructions given below.

Modify the Windows Environment Variables:

• Step 1: Tap the Win + X keys and then select System. After that, it will open the section where you can see all the properties on your computer.
• Step 2: Next, select the Advanced system setting located on the left pane and click on the Environment Variables.
• Step 3: After that, locate Path under the System Variables and select EDIT.
• Step 4: Before you edit, you need to copy the entire string and paste it into the Notepad app so that in case something went wrong, you can paste it back.
• Step 5: Next, look for the directory path, “C:\Windows\System32”. If you can’t find it, try adding a semi-colon at the end.
• Step 6: Afterwards, click OK to save the changes made and then exit.
• Step 7: Now restart your computer as all the paths are picked up when your computer restarts.

Note: Now all you have to do is to try executing the programs once again – the ones where you got the error, “ is not recognized as an internal or external command, operable program or batch file” every time you open them and then see if you can now open these programs or not.
