I decided to finally upgrade to Windows 11 22H2 on my host machine. Upgrade was smooth and all seems to be running fine until I started Vmware Workstation Pro 17. All my Windows guests booted very slow and they even froze so I had to shut them down. Restart did not help and what was running smoothly before was extremely slow and unresponsive. I had to downgrade my host machine Windows back as I did not find any workaround. I found something mentioning Microsoft introduced its own Hypervisor or something but there were just some questionable workaround to uninstall/disable something.
ANyone else is experiencing the same on the latest Workstation 17 Pro and Windows 11 22H2?
Probably HyperV is installed/pre-configured.
In order to turn off Hyper-V mode, run the following command at the host in windows command-line with Administrator privileges:
bcdedit /set hypervisorlaunchtype off
Reboot the system to activate your changes.
If you want to go back to Hyper-V mode again, then you can enable it like this:
bcdedit /set hypervisorlaunchtype auto
Note that you also might have to disable Memory Integrity.

Am facing the same issue with VMware workstation 17. Looks like it has some serious issues and a bug fix MUST be released.
Any operations we do with 4 or more VMs running will spike the CPU immediately to 100%. This will result in VM hangs.
Running the base OS as Windows Server 2016 Datacenter with latest update, 160 GB RAM and many CPUs.
I hope VMware releases a patch or an update for this.
In my opinion disabling security features is not a solution, especially when computers are managed centrally and there is no option to turn it off. VMware team should work with Microsoft to solve this issue.
If you are experiencing very slow performances with Alder Lake CPUs, I solved the issue using
powercfg /powerthrottling disable /path "C:\Program Files (x86)\VMware\VMware Workstation\x64\vmware-vmx.exe"
It's still slow. I'm checking for updates on Windows and VMware everyday hoping they found a fix. No luck. VMware doesn't make it easy to contact them for support either. I'm not happy that I can't create a ticket with them without paying for it.
Holy moly, the power configuration change helped... I'm dumbfounded. It's still not like before the Windows 11 update, but it's a significant improvement. I'll test it out some more and see how it goes.
My Windows 11 VM running under VM Workstation Pro v17 on a Windows 11 guest had been painfully slow to use. I had already applied the settings suggested by maksym007, but it was still just as slow. Adjusting the power throttling setting as suggested by giopebero has made a huge difference to the performance.
I would suggest applying both of these changes to see if it fixed you performance issues.
Having tried Hyper-V to see if that performed better, I'll be sticking to VM Workstation as it is so much more functional. I needed to disable Hyper-V on my system to get the Intel VT-x/EPT enables for my VMs. I will not miss Hyper-V functionality.
