Computer 1 - A Win7 machine. Won’t be impacted by this.
Computer 2 - A Win10 machine that is Win11 capable. Will upgrade this one.
Computer 3 - A Win10 machine that struggles on Win10 and modern version of Linux. Won’t try to upgrade this one. It’s 4 years old and HP messages me regularly that they won’t provide parts or service any more.
Computer 4 - Win7 that I upgraded to Win10 when Win10 first came out. So likely 15 years old. Not going to even try.
So it looks like I’ll have one Win11 machine and 3 that work.
As a stockholder in various companies, however, I recommend that everyone reading this thread buy a new HP machine and Win11 from Microsoft. You’ll have my thanks for that.
I have 5 year old HP laptop that is not officially sanctioned for Windows 11 but runs it with no problems at all. Windows 11 is not perceptibly any more demanding than Windows 10 for fairly modern hardware. Older hardware can sometimes present some challenges when trying to hunt down drivers, etc...
It sounds like your 4 year old HP could use a clean install leaving out all the bloatware that HP typically includes. It is also possible that you have some iffy components or bad settings in your UEFI/BIOS.
