OS/2's main problem was that it was only preinstalled on expensive IBM hardware that almost nobody wanted to buy when cheaper hardware was available from IBM PC clone manufacturers like Compaq. The hardware also used MCA, which was more expensive than ISA thanks to IBM's royalties and it was a pain to configure. Nobody wanted that. That sealed OS/2's fate.
That is not mentioning the horrible marketing campaign for OS/2 Warp that made OS/2 sound like it was related to narcotics.
Anyway, had OS/2 been on all of the IBM PC clones rather than Windows, then history would have selected OS/2 over Windows.
Android on Windows requires Windows 11, is US only and uses Amazon store, hardly a success.
WSL is being a success to drive Windows sales, because as Microsoft learned from Apple's customer base, it turns out many developers only care about having a POSIX environment and couldn't care less to support Linux vendors Additionally it helps selling Windows containers on top of Docker tooling, for the same kind of customers.
That is the target, nothing else.
The target platform keeps being Windows x86/x64 in what game developers are concerned.
Since Windows CE days for ARM, the amount of device sales have hardly been spectacular, hence Project Volterra, which isn't taking the world of Windows development by storm in any way.
