You think the US govt will let MS drop 2/3rds of US citizens laptops from support?
I think some senators will hold a hearing to grandstand about security and forced obsolescence and MS will be shamed into extending the support window a couple more years.
Windows 10 is over 10 years old at this point. Microsoft learned from XP It can’t live forever.
Businesses typically lease their machines for 2-3 years so they all support 11. And do you really think the government cares about regular citizens? lol.
But most hospital computers won't be exposed to internet right? And they probably run a bunch of propriety software that only supports xp so makes sense it took them a long time.
Windows 10 Enterprise LTSC 2019 has a 10 year support window, and subsequent LTSC versions, 5 years. If you can get your hands on one of these licences you would presumably continue to receive security patches. If the US government is somehow not running on this kind of licence, it would be pretty funny, but I'm sure Microsoft would be lenient and let them jump onto whatever compatible LTSC version given its an American company.
