My main desktop had the same installation of Windows for 15 years, from Vista in 2007 right the way through to 10 in 2023, having upgraded through every intermediate version. I only finally did a fresh reinstall for 11. I would copy the hard drive contents from one drive to the next each time I bought a new drive, and ultimately that installation survived three complete hardware refreshes and countless interim component upgrades. Needless to say, there was a LOT of cruft hanging about by the end. From ancient components from old versions of Visual Studio to drivers for early 2000s era scanners. Most of it still ran too, testament to Microsoft’s backwards compatibility.
