windows menus border lines problem [Image included]

Transparency effects is also the shader so that confirms where the problem is.

As a check on driver installation go to the Device Manager and look at what has happened.

Device Manager > Display Adapters >
There should be two in there Intel and Nvidia.
Right click on the Intel one and > Properties > Events Tab >

This is mine that shows the sort of thing going down the events list, only relevant ones detailed:
Intel
last line Device installed......ending in status 0x0:
12/04/17 08:28:22
Nvidia
12/04/17 08:23:46 Device install requested
12/04/17 08:24:07 Device install requested
12/04/17 08:28:23 Device install requested
12/04/17 08:29:04 Device migrated
12/04/17 08:29:36 Device installed...ending in status 0x0

That shows that Windows updates did the right thing, only installing the Nvidia driver after the Intel one first.
So you should have something similar along those lines.

im not getting this line in neither of the drivers (Device installed......ending in status 0x0)

You need to scroll down that box, it's the last entry that should have 0x0
The Nvidia driver install, device migrated, should be following that timestamp. Though there maybe requests before it actually starts.

Attachment 155576

both intel and nvidia have 0x0

@syrioust

It's because you are using 'Aero-Lite' theme, switch to Windows default theme and the thick borders should disappear.

wow that actually worked! i feel so stupid. eventhough i havent changed the themes once in my life in windows 10 it was somehow changed, and using the windows 10 theme solved this problem. thank thou very much for thine help, all of ye. "Solved "

No worries mate! We've all been there!
May have carried over from your previous OS. Glad you got it sorted.

The Aerolite theme is not part of Windows 10.
Anyway you it solved.
