Interesting that a couple of people are commenting about a very old vbscript tool not working anymore, with an 80004005 error…. that’s an access violation, something you’ll typically see because of a programming mistake.

There was a security fix for VBScript this month, so something was jiggled in this area of Windows.

I have 4 installations of 1809 (dual-boot desktop, laptop, NAS) and I’ve noticed nothing untoward on any of them.  The only third party AV tool I use is Malwarebytes Premium, alongside Windows Defender.  No issues, no problems.

Always create a fresh drive image before making system changes/Windows updates; you may need to start over!

We were all once "Average Users". We all have our own reasons for doing the things that we do to our systems, we don't need anyone's approval, and we don't all have to do the same things.

I also use MalwareBytes and Windows Defender with no slowdowns.

1809 with SentinelOne, no issues…

FWIW I’ve noticed massive slowdowns while trying to install the Windows 7 March patches onto our Virtual Desktop Infrastructure.  In testing March updates on a single desktop wasn’t causing issues, but we saw large amounts of slowdown and freezes when rolled out to ~150 desktop clones.

With the April updates, we saw freezing when running just a single image.  I don’t think this is an April issue, I think a change in the March updates is being magnified by the most recent patch.  IE seemed to cause the most problems for us, but it was slow overall.

Hm.

With a sample size of exactly one so far over here, I haven’t noticed any significant problems after KB4493509, and just happen to have Sophos on this one too.

Took a while longer than average for the desktop to stabilize after a screen geometry change (laptop, two desks, docks with different monitor setups) but stabilize it did.

I *have* noticed problems on other systems today though… but not caused by these updates. Something weird going on with OneDrive client new logins on Windows 7, though.
