It'll be Linux-based, as I've always mentioned by the time Microsoft gets its OS fixed it'll be Linux. The only problem is that there will not be a large market share for Linux and an onslaught of Linux malware and viruses. In a perfect world Microsoft would admit every OS of theirs after Windows 7 is a total piece of shit and bow out of the operating system business. With only its excellent consoles and games still in operation.
Microsoft knows every one of the 8-10 operating systems is a horrid piece of shit, which is why new PCs started blocking Linux installations with UEFI. First Google steals open source and profits from it with Android and now Microsoft is stealing all the work countless people did for no profit too. Then corporations complain about piracy when the wealthiest of them are the ultimate pirates. Once Windows 11 rolls out it'll be a final admission that Microsoft has had its head up its arse for 3 versions and that Linux is the superior OS. Get ready for all the viruses and malware that will ruin Linux to infect the new Windows.
