Crashed OS need to be changed

no know much about politics. for os that run on old machine will normally work well.
over time hardware changes but the core os still the same.
like russia and china who is moving away from ms os, the core is still unix. a variant of unix. (ms os itself also a variant of unix)
ms os is no more as strong as it used to be as people start to move away from american base due to over harvesting
of their soft power to band this and band that. so people got wary move away.
