With 21277.1000, this old bug is back, it does not cleanup Windows.old completely 393 KB are left, 2 files showing, bcd.dll and bootsvc.dll, this bug was previously fixed with Build 20257 :

I found the same on my laptop. Restarting removed the two files but left the folders which were easily deleted.

Ok, thanks

On my primary system right now so can't confirm exact number but was either 457.51 or 456.71 offered through Windows Update.  I had been running the 460.20 over the last few updates and that driver didn't allow me to change to higher refresh rate, the older one did.  I didn't try the newer one from Nvidia on my Insider one, but am running that version on my Primary system with no issues.  I will have to boot back to the Insider drive and try the 460.79 one.

edit - running 456.71 from Windows Update, was running 460.20 and was offered the older one as an optional driver "update"

edit 2 - Now running newest driver from Nvidia 460.79, am able to run my 240 Hz refresh rate with no issues.

Ok, which monitor are you using that allows 240 Hz refresh rate ?
