Laptop acting weird after Windows 10 Fall Creators Update

[AMDGrill]

As the title says, ever since I updated my Windows, I am having the trouble following:
 

• Incredibly slow response time on desktop Right Click
• Games going black screen when played in Fullscreen. Happens in GTA V, Titanfall and Guardians of Orion

 

Tried a few things online and can't seem to find a solution, so where better to go.
System specs summary:
i7 7700HQ
16G DDR4 2133
256gb SSD + HDD
GTX 1050
 

All drivers are up to date. No bloatware. Was not a problem before the update, and the PC is in the same condition. No hardware changes, no new software.

Any help is appreciated

I think is probably the OS bug.

Have you tried reinstalling the drivers for your GPU through NVIDIA, rather than through windows update?

[AMDGrill]

Yes, I have reinstalled many of the software and drivers after the update, doesn't seem to work.

Update:

Fixed. 

Deleted the following from regedit and both problems are gone. On a side note, Intel, get your bricks together.
