Windows 10: issues with windows but main question right now shift click not working

I truly appreciate any help and not here to be rude. I purchase laptop with window 8 for touch that never worked. Now due to work request upgraded windows 10 now many things do not work but try to mass delete files from anything like file explorer, facebook, etc most alt,shift, ctl functions do not work.

Windows + Shift + right doesn't shift window to the right screen (shifting to the left works fine)

When I use Windows Key + Shift + left the active window jumps to the monitor on the left like expected
But when I try to do it the other way around: Windows Key + Shift + right the window doesn't jump back to the right Nothing happens. Why? How can I fix this?

PS: I am using Windows 10 Version 1903 (64 bit) on my ThinkPad with two additional external monitors.
Windows Key + right moves the window correctly to the right (step by step but not directly to the next monitor).
Maybe the Windows Key + Shift + right was overwritten by something else? How can I find out?

 

Intel Speed Shift Technology Skylake

You just need a Skylake CPU and ThrottleStop, once turned on speed shift you can exit the software as unclewebb said above.

 

shift keys not working

I upgraded to windows 10 on my Toshiba laptop and then did the windows update and when I tried to do anything with the shift key neither one works. I read all the suggestions I could find in here and tried most of them with no luck. I ran the hardware
and device troubleshooter, I went to the keyboard on control panel and it says it's working properly. I tried shift/control/alt keys all together. I downloaded and scanned with anti malware and I did the fn and del keys with no results. I would like an easy
fix for this as I believe it is a windows 10 and or update for windows 10 issue. I am not real savvy on the computer so I need step by step instructions, please and thank you.
