Dealing with slow VMs in Windows 11
Friday, April 11, 2025 by Frogboy | Discussion: Stardock Blog
I recently got back into Virtual Machines and found the performance terrible on Windows 11.
I couldn't figure out why. There was noticeable input lag and even moving windows around was sluggish.
I looked on Reddit and elsewhere and got advice about installing tools or configuring the VM differently but eventually just had a feeling that it had something to do with security on Windows. So after a lot of trial and error I found this option:
Now, I am not recommending you disable this. But on my home box, that is behind firewalls and I am using myself in relative isolation, I felt comfortable turning this off when doing VM work. Doing so brought VM speed back to where you would expect it.
Hoe this helps.

Curiously, my messing with VMs currently has me with a Windows 10 VM on a Windows 7 machine. I may yet attempt to put an 11 VM on, though I expect a lot more hurdles.
Hard enough having to run a compatible VMWare for a 7 host...
