Fix #1: Check Software Protection Service.

Since this error is closely associated with Software Protection Service, the first thing you need to do is to check if the service is running. If it is not, you need to turn it off for Windows Activation to proceed smoothly.

To start Software Protection Service, follow the steps below:

  1. Press Windows + R to launch the Run dialog.
  2. Type in services.msc, then press Enter.
  3. Scroll down to Software Protection, then double-click on it.
  4. In the Software Protection Properties window, click the Start button, then OK.

Once the service has started, reboot your computer and try to activate Windows again to see if it works. If you’re still seeing the error message after starting the service, you might have some permission or file issues preventing Software Protection from running. To fix this, follow the instructions below:

  1. Click Start then type in command prompt in the search box.
  2. Right-click on Command Prompt from the list of search results and choose Run as administrator.
  3. Type in the following command, followed by Enter:

Icacls %windir%\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft\SoftwareProtectionPlatform /grant “BUILTIN\Administrators:(OI)(CI)(F)” “NT AUTHORITY\SYSTEM:(OI)(CI)(F)” “NT Service\sppsvc:(OI)(CI)(R,W,D)” “NETWORK SERVICE:(OI)(CI)(F)”

  1. Close Command Prompt.

  6. Close Windows Explorer and go back to the Run dialog by pressing Windows + R.
  7. Type in %windir%\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft\SoftwareProtectionPlatform\, then press Enter.
  8. Find the dat file and right-click on it. Select Rename and change the file name to tokens.bak.
  9. Hit Enter.

This should fix any permission or file issues with Software Protection. The next step is to make sure that the service starts automatically during startup. To do this:

  1. Open the Run dialog using the instructions above.
  2. Type in services.msc, then press Enter.
  3. Double-click Software Protection.
  4. Under Startup Type, choose Automatic.
  5. Click Start, then OK.

Restart your computer for all these changes to apply, then try to activate Windows again.

Fix #2: Repair Missing or Corrupted Files.

If the error is due to missing, damaged, or corrupted files, running the System File Checker usually resolves this problem. To run SFC, follow the instructions below:

  1. Click Start, then choose Command Prompt (Admin) from the Power Menu.
  2. Type in the following commands in the terminal:
    • WSReset.exe
    • dism /online /cleanup-image /restorehealth
    • dism /online /cleanup-image /StartComponentCleanup
    • sfc /scannow
    • powershell
    • Get-AppXPackage -AllUsers |Where-Object {$_.InstallLocation -like “*SystemApps*”} | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
  3. Press Enter to execute the command.

Wait for scan to complete and follow the on-screen instructions to resolve any issues detected by SFC. Try activating your Windows to check if the issue has been fixed.

If not, you can run a deeper scan using Deployment Image Servicing and Management (DISM). To do this:

  1. Launch Command Prompt as an admin using the instructions above.
  2. Type in the commands in the Command Prompt windows, then press Enter after each line to execute the command:
    • Dism /Online /Cleanup-Image /CheckHealth
    • Dism /Online /Cleanup-Image /ScanHealth
    • Dism /Online /Cleanup-Image /RestoreHealth

Let DISM do its work, then reboot your computer after the process is completed. Next, check if you are now able to activate your Windows without any errors.

Fix #3: Check for Permission Issues.

Another reason why 0xC0000022 error occurs is insufficient administrative rights. To acquire admin rights to your computer, follow the instructions below:

  4. Click on the Security tab, then click Advanced.

In my case, a simple “Sfc /scannow” command, typed in the command prompt and a reboot after it solved the problem.
