Windows 11 VMware fix - get your speed back - No more error messages

Disclaimer: This worked for me and it seems its a general fix. So I think this will work for you too.

VM-Ware had many issues on Windows 11 since the release and I found this fix to work. I did nothing else and I got my speed back to my VM´s and they started to work.

Step-by-step:
1) Open a administrator CMD and type "bcdedit /set hypervisorlaunchtype off".
2) Search for "Core Isolation" and turn it off.
3) Restart your computer

Like my videos? Would you consider to donate to me I created a possible way for you to do that.

I've tried these solutions and yet nothing has helped.
