Hi @dc74
In knowing that, if you have Bitdefender installed on the Windows 10 PC, I would do a complete uninstall from Apps. Then go into your Central account and remove that PC from your Devices. Upgrade, install Windows 11 (if your PC meets the requirements) then follow Flexx article to install from your Central account, to "this device".

Sorry, my questions was a bit unclear. I want to upgrade from Windows 10 to Windows 11 and I've seen that other people have had an issue with Bitdefender in the process. Any suggestions?
