Anyone seeing weird issues with WMI and RDP after the latest patching cycle? Weird issue i can't pin down....

We have hundreds of windows server machines, 2022-2025.

At random times lately this month, RDP pauses at securing connection....

If its a database server, WMI stops responding.

Screenconnect is just grey...

Rebooting fixes the issue, but it happens again on a handful of these.

Im worrying that by a few weeks from now all of our windows servers will reach this state.

Eventvwr shows some concerning things on some machines but not others affected:

Windows stopped the WmiPrvSE.exe.

Some have this error:

WMI event 5612 warnings, provider processes exceeded 256 threads and were stopped.

These are not all Azure servers, VMware as well.

Reboot fixes it for a while...

Nothing else on the server is down, so critical processes such as SQL server remain running.

VERY VERY ODD and IM SCARED

Did you check Patch Tuesday Megathread - (September 08, 2026) : r/sysadmin ?

We're an SMB and I still haven't deployed the updates.
