If you are a veteran Windows user, you are probably no stranger to blue screens of death, disk failures, and system file errors. One of the serious errors that affects the normal operation of Windows is the infamous 0x8007012a installation error. This is a rather specific error that prevents your computer from downloading and installing new updates.

Below are 6 tips you can try to get rid of the 0x8007012a installation error.


Solution 1. Restart your computer

Some problems can be solved without too many complicated operations. In fact, you will be surprised how rebooting your device can save you from all kinds of trouble.

So, in general, it's best to try restarting your computer before diving into more complex fixes, unless the restart itself won't happen.
