Very fast updated ..........no sign of fixing the "optimize drive"- bug !!

I just took a quick too and I think it might be fixed, anyone else?

It seems to know when it last run - so far!

Not fixed, you have to restart to manifest itself.

Ah - shame

Yep - as you say it's broken after restart!

CountMike said:

Usually does, specially with security updates like this one.Whn you have a 3rd party AV, Defender gets turned off.

Ok so what do I need to do then? I just uninstalled RIOT VANGUARD. and I followed this video youtube.com/watch?v=mgyK88z3e5Y but it wont let me completely disable ESET. do I need defender enabled or what is going on with that.

This sounds like a broken record now, but OMG! When will Microsoft fix this optimize drive bug....... This is absolutely beyond ridiculous... Guess I'll wait to September before upgrading now, and hope it's fixed by then. yay!

did you even bother to check what version of the defrag.exe, defragsvc.dll & dfrgui.exe files from the Windows\System32 folder, Faith?

until MS actually provides NEWER versions of those crucial defrag files in newer cumulative updates, the defrag problem WILL STILL REMAIN UNFIXED! (if those defrag files are version 10.0.19041.84 or earlier for 20Hx)

Nor me, I have enabled the 20H2 Start menu etc
