No. We kind of suspected McAfee products since when we upgraded from Windows 7 
x64 to Windows 10 1607, we removed all McAfee products prior to the upgrade and 
we did not have disk encryption at the time.

Since then, we now have a slew of McAfee products (Drive Encryption,  DLP, MAR 
McAfee Active Response, Application Control, WebControl, etc).

As a test, we removed DE, MAR, Application Control and managed to get it down 
to 2 hours.

But Stephanie only has BitLocker and one language (en-US) and they are 3+ hrs 
as well.

I have no other steps in my TS other than Upgrade, even removed Dynamic Update, 
ran cleanmgr.exe to remove old Windows installs, remove all but one user 
profile . . . (ConfigMgr is running 1710, our OS Upgrade Package is 1709 and 
serviced up to December’s cumulative update and Adobe Flash)

are you using anything like Bit9 (Carbon Black) ? I've seen lenghty delays when 
that's enabled, not just for upgrades but even for installing a cumulative 
update..

Thank you very much, Stephanie.

I am stumped as to why it is so much longer now, almost 4 x, compared to Win 7 
to Win 10 1607.

We’ll keep digging.
