So far everything except my printer is working in Windows 11. I am running it on a separate SSD than Windows 10. So I switch back and forth depending on what I want to use that day. I have a Canon Pixma MG2220 that works great in Windows 10. But Windows 11 sees the printer but it won't let me...
I am running Windows 11 in VMware and have noticed the same thing. Everytime I boot up Windows 11 I have to manually start Defender. I don't have any other antivirus or malware software installed as Win 11 is a new stock install from UUP Dump.
