Several versions of Windows 10 received cumulative updates earlier this week on this year's first Patch Tuesday. While the focus was mostly on the security bugs being addressed, Microsoft has also fixed the "Reset this PC" bug that was failing to work for many users.

Using the “Reset this PC” feature, also called “Push Button Reset” or PBR, might fail. You might restart into recovery with “Choose an option” at the top of the screen with various options or you might restart to your desktop and receive the error “There was a problem resetting your PC”.
