Explorer flickering and mouse icon flickering were unrelated as i suspected!
Final Solution that worked for me:
Mouse flickering issue fix: Uninstall Spiceworks (Suspecting it was trying to run something and may be crashing due to lack of admin rights)
For Windows explorer flickering issue, i just disabled the "preview pane" and it fixed that problem as well!
Spiceworks is not supported in Windows 10...
oh! It worked when i ran (was checking the inventory part for something i needed internally), but i guess that explains why!
