Windows 10 is one of the most updated operating systems on the market, barely a day goes by where there isn’t some form of update being pushed out.

To begin, there are a few simple steps that you should always take if you suddenly start getting a new error message. First, make sure you have scanned your entire computer for viruses and malware. Then uninstall any new programs or apps that you may have installed just before the issues started. If this doesn’t fix the issue you can Restore Your Computer to a slightly earlier time.

To do this type Restore into the start menu, then select the recovery option when it appears on the list. Next click Open System Restore, choose one of the two options on the system restore window. Recommended Restore will use your most recent restore point, however, you may wish to manually choose a point from earlier, if so, choose the second option then follow the system instructions.
