Ah, should have been even more clear...When I wrote this I meant I'd given up on the upgrade on this computer. Once I knew I'd need to install the upgrade entirely to opt in, I said the hell with the free upgrade. My only issue is that Windows Update seems stuck in limbo.I decided it wasn't worth upgrading then immediately reverting back, since this computer really doesn't need anything newer than 7 anyway...
This is, yesterday, I got my first batch of updates since the botched upgrade. It installed 5 updates automatically, so it still seems to be doing its job. Funny thing is, under 'view update history' it only shows those that were installed since the attempted upgrade. Under 'installed updates' though, it shows all the updates since last installing Windows....
