My PC is currently on W10 Home edition. I just bought this PC 4 years ago and its awesome! I ran the Windows 11 compatibility checker to see if my
Aspire TC-780 can be upgraded to Windows 11 to continue getting security updates. Everything except for the processor which is
Intel(R) Core (TM) i7-6700 @3.40 GHz, 3408 Mhz, 4 Core(s) 8 Logical Processor(s). My Desktop PC runs very well and I do not want to purchase a new one when it works just fine. Is there a compatible processor I can upgrade it to? I understand Windows 10 support will end December 2022.

I understand W10 Pro is supported through 2025 but I am not sure if there will be a cost for that as they did with Windows 7. Does Acre sell parts to upgrade???
FAQ & Answers
It is a Bummer but I've been thru many Windows from 3.1 till now. Normally by the time MS quits updating, the computers have gotten slow and outdated to newer software thus virtually obsolete.
I'd save my money to but a new unit it 2025 rather than trying to update a 4 year old computer. Good Luck.
