Sorry to hear that, @Sarge!

-Periodical system images, save some older ones just in case. No userdata and not all programs installed to C: to reduce image size. Back up other non WIndows stuff by other means.
Still going strong, soon 14 years on the same WIndows installation, of course with a couple of Windows and hardware upgrades on the way. Occasional BSOD, but far between, due to some very old drivers, apps and services, and can live with that.
Looking forward to this!:
Amazing work with all your extensions, by the way!:

Good luck with the reinstallation!
