Never ending loading screen starting my computer

Those updates are from a few weeks ago, from the monthly patchday https://support.microsoft.com/en-us/...update-history & July 2016 security update release MSRC
The monthly patchday is every second tuesday of the month.

Please do 1 more thing for me to ensure that there is no system file corruption :)

Diagnostics Test

 System File Check

Please try following:

• Open an admin command prompt
• Copy/paste "sfc /scannow" (without quotes) and press enter
• When it is finished reboot your system
• Open again an admin command prompt
• Enter sfc/scannow again

If sfc/scannow says "Windows Resource Protection found corrupt files but was unable to fix some of them" after the second SFC, please upload the cbs.log file located at %systemroot%\Logs\CBS\, if the file is too large try a 3rd party uploader like dropbox, onedrive, google drive, mediafire etc.
System File Check(SFC a.k.a. Windows Resource Protection) needs to have your system rebooted in order for sfc to try to fix the problems that it finds.

Make a photo of SFC and post it.

Excellent

You're 'good to go' as some people would say :)
