Windows 10: Update KB4559309 Makes Computer Unbearably Slow

Last night I updated my windows 10 pro using KB:4559309. Since then my computer performance has absolutely tanked. my startup time is probably triple, loading any window has a few second delay.


I attempted to uninstall the update however windows tells me that it is required and cannot be removed.


This update has essentially rendered my brand new computer useless.


Please help!

Computer UNBEARABLY SLOW After Anniversary Update

My computer is unbearably slow after the Anniversary Update. Tried everything I can think of, which is basically CCleaner and SFC /SCANNOW. Nothing has seemed to work. What should I do?

My version of Windows 10 x64 is a free upgrade from Windows 7, if that means anything at all.

I don't really see a point in using System Restore, I could be wrong, since System Restore might had taken me to a point before the Anniversary Update.
