Windows 0x80070020: Resolving File Access Conflicts During Update

The 0x80070020 error in Windows typically occurs when there are file access conflicts during an update.

This can happen if other programs, including antivirus software or system processes, are using the files that Windows Update needs.

To fix this error, start by restarting your computer.

This will close any programs that might be interfering with the update process.

If the error persists, try disabling your antivirus software temporarily, as it can block access to the files needed by Windows Update.

Also, ensure that no other programs or processes are using system resources by closing unnecessary applications from Task Manager (Ctrl + Shift + Esc).

You can also try booting into Safe Mode to install the update.

In Safe Mode, only essential system processes run, which can eliminate conflicts.

To do this, go to Settings > Update & Security > Recovery, and click on Restart now under Advanced startup.

Then select Troubleshoot > Advanced options > Startup Settings > Restart and choose Safe Mode.

Once in Safe Mode, try running the update again.
