So not sure where to ask this. My PC is nagging me to upgrade from Windows 10 to Windows 11... I don't know if there is any value to do it. Usually, fresh windows install take 3 days with updates and more updates... they are really annoying.


I have no idea where my D2 keys are since I have had the game since 2000, further, I have no idea where the digital key went, or what my Blizzard account or password are.

(a) So, will upgrading to Windows 11 "poof" my diablo2 installation, or will it continue to work without having to reinstall it? (I'm not on D2R yet)
(b) Also, I have office 2019, will that continue to work, or do I have to do reinstalls-- cuz I have no idea where I put those credentials either


thanks in advance.

just dont upgrade

Theres probably a tool or a method out there to find the cdkey you installed the game with.

Use the windows installable usb tool to get a version of the installer / upgrader that's quite up to date too.
