A. Try to boot 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 > Advanced Options > Startup Settings > Restart
Press 4 or F4 to enable Safe Mode (5 or F5 to enable Safe Mode with Networking)
Log in once Windows starts in safe mode
Once you are able to boot into safe mode, check the integrity of the system
B. Another option when you are in Advanced Options in previous step is to choose (Note - You won't lose any files in this step)
Startup Repair - Startup Repair upgrade fixes all Windows errors and retains all files, applications and settings.
C. Last option could be Reset this PC.
In Step A > 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.
