Hi [NAME]  welcome to this user to user discussion forum.  Support for Alienware Area-51m Drivers & Downloads does not include Windows 11, 64-bit and the Windows 10, 64-bit BIOS, Alienware Command Center Application, etc. have not been updated to be used on Windows 11, 64-bit.  The official release date for Windows 11, 64-bit has not been revealed.  Seems the fix is to reinstall Windows 10, 64-bit and wait for release of Dell Drivers & Downloads that are designed to run on Windows 11, 64-bit.

I tried Windows 11 and first I want to try reinstall Alienware Command Center but all it give me was access denied. I go to Windows Securities but it wont open. It told me to go to Windows Defenders app but I couldnt find it. What to do?
