After doing that, your proxy should be disabled and the update error 0x80242ff should be resolved. If you still want to protect your privacy online, we strongly suggest that you consider using a VPN instead of a proxy.

There are many great VPN services available, and one of the best is Private Internet Access (PIA), so be sure to try it out.


Sometimes, the proxy can’t be disabled. We’ve prepared a simple guide for such situations.


3. Check the integrity of your system files

  1. Press Windows Key + X and select Command Prompt (Admin) from the list (or PowerShell for older systems).

  3. The SFC scan will now start. The scanning process can take about 15 minutes, so don’t interrupt it.

This process finds and fixes corrupt files, if any. Once the SFC scan is finished, check if the problem is still there.

If it is, you need to run a DISM scan. You can do that by following these steps:

  1. Open Command Prompt as administrator.
  2. Now run the following command and press Enter: DISM /Online /Cleanup-Image /RestoreHealth
    Error 0x80242ff Windows 7
  3. Once again, the scanning should take about 20 minutes, so don’t interfere with it.

After the DISM scan finishes, check if the problem is resolved. If you want, you can also repeat the SFC scan once again and check if that solves the problem.
