I haven't had to reinstall Windows since 2011. Currently on the latest Windows 11.

>but you had to install Windows 11 to upgrade from Windows 7 which was the latest OS in 2011!
I just updated, still kept all the programs and data and registry
>But your hard drive must have been replaced!
Ghosted it over to the new PC. Installing a new hard drive was just a speed boost, not a reinstall
>how can you even tell that your windows install is that old?
Oldest directories in %localappdata% are from 2011.
>your Windows install must be super slow!
Nope, checking the task manager shows nothing using up all the resources. CPU is less than a few percentage usage with a few VMs open
>your system must be completely buggy and unstable
Nope, everything is running fine. I even run system file checks and nothing is found of issue.
