Reset Windows Update components, stop the wuauserv, cryptSvc, bits, msserver services, and clear the SoftwareDistribution and catroot2 folders before restarting the service; 4.

Windows Update Error 0x80080005 Usually occurs when trying to update the system, prompting messages such as "Cannot update system files" or "Access denied". This problem can be caused by a variety of reasons, such as system file corruption, permission issues, or third-party software interference. Here are some common and effective solutions to help you deal with this error.

Check system file integrity
Windows has a built-in system file checking tool (sfc and DISM) that can be used to repair corruption or loss of system files, which is the first step in solving 0x80080005.
- Open a command prompt (run as administrator)
- Enter the following command and press Enter:
sfc /scannow
- If the scan is completed but the problem remains the same, continue running:
DISM /Online /Cleanup-Image /RestoreHealth
These two commands check the system files and try to fix the corruption. The whole process may take some time. After completion, restart the computer and try to update.

Turn off third-party antivirus software or firewall
Some third-party security software prevents Windows Update from running properly, resulting in a 0x80080005 error. You can try to temporarily disable these software, especially like Kaspersky, Bitdefender, Malwarebytes, etc.
- Find the security software icon in the lower right corner of the taskbar
- Right-click to select "Exit" or "Disable" (some software provides "temporary disable" option)
- Then try to update again
If the update is successful, it means that it is a conflict caused by the security software. You can consider replacing or adjusting its settings.

Reset Windows Update Components
Sometimes, Windows Update's own components may have exceptions, causing update failures. You can try resetting these components:
- Open a command prompt (administrator)
- Run the following commands in turn:
net stop wuauserv net stop cryptSvc net stop bits net stop msserver
- Then delete the contents of the following two folders (note: you can back up before deleting):
- C:\Windows\SoftwareDistribution
- C:\Windows\System32\catroot2
- Run the following command again to start the service:
net start wuauserv net start cryptSvc net start bits net start msserver
Once you're done, try checking for updates again.
Check disk space and system permissions
Windows updates require sufficient disk space and correct system permissions. If the C disk space is insufficient (it is recommended to keep at least 10GB or more), it may also cause the update to fail.
- Open "This Computer", right-click on disk C, and select "Properties" to view available space
- Use the Disk Cleanup tool to delete temporary files and system update residues
- Also, make sure you are using an administrator account, otherwise some updates will be denied
Basically these are the methods. You can try it in order, and in most cases the first two steps can solve the problem. If it still doesn't work, it may be caused by a system version or driver conflict. You can consider manually downloading the update patch or upgrading the system version.
