@BrideOfLinux I have the same Ubuntu #Linux VM going nearly 5 years now with 8 GBs of RAM and it never slows down or acts weird. Right now, it has a #Firefox session with probably about 40 tabs open. I'm just waiting until #Microsoft stops issuing feature updates and remove the #Windows11 and replace it with Linux.
@adacosta I'm expecting that MS will eventually base Windows on Linux or BSD.
@BrideOfLinux I don't think so, Microsoft's aim is to move the client to the cloud like ChromeOS. Thats why I believe there will be no #Windows12 and push will be to move everyone to #Windows365 at the beginning of 2030.
