The most common cause for update error 0x80242ff can be your antivirus. Sometimes a third-party antivirus can interfere with your system and cause problems with Windows Update.

However, you can fix this problem simply by disabling certain antivirus features or by disabling your antivirus altogether.

If disabling the antivirus doesn’t fix the problem, it’s advised that you remove your antivirus and check if that solves the issue. Several users reported that removing their third-party antivirus fixed the issue for them, so you might want to try that.

If removing the antivirus solves the problem, it might be a good idea to switch to a different antivirus solution.
