I was in that situation a while ago, so I booted in to try and keep it up to date. Well, in reality I booted into recovery mode as it decided to die. Anyway I'm now duel booting arch and tumbleweed
At that point I'd just get rid of Windows entirely. I used to have it on my laptop, and the updates it installed after booting for the first time in months broke networking. I never used that install so I decided to use the storage space for more sensible things.
