According to Statcounter, Windows 11 held a 55.18% market share in October 2025. That share dropped to 53.7% in November and dropped again in December. Now, Windows 11 holds a 50.73% market share.

Many are rollback to Windows 10, but Linux is increasing as well.

The only thing stopping me from moving from Win10 to a new rig on Linux Mint is ram prices.
Just install Linux on the old rig.
Honestly, given that Mint is a Debian distro (before anyone yells at me, its an Ubuntu distro that itself is a Debian distro) it will work better out of the box on less up to date hardware. Debian prioritizes stability so it’s repos and drivers are months to years old. Older hardware will have stable working drivers meanwhile new hardware may have to work with experimental or generic drivers.
