Have you tried to reset your computer while booting into safe mode
Power ON your computer and as Windows / manufacturer's Logo appears, Power OFF - Repeat 3 times
Now your computer will go into Advanced Recovery Environment
Advanced Options > Troubleshoot > Reset this PC - Keep my files and Remove everything. Choose this carefully as most likely you would like to keep your files.
All apps will be removed and windows will be reinstalled.
Do let me know if you have any more question or require further help. I would be happy to work with you to take you though this problem.
