First, please let us know exactly what the error message says. Most likely this is due to something that had been changed about your installation.
I'm not familiar with how to recover from this error - other than to try resetting the computer into the default state for Windows.
See this article for a brief look at how the push-button reset features work: https://msdn.microsoft.com/en-us/library/windows/hardware/mt210509%28v=vs.85%29.aspx
As there are problems with the installation, I'd have to wonder about the risk to your data anyway.
Attempting to revert could cause problems if forced.
I'd suggest backing up your data and then going with the Reset using the Remove Everything option.
