Any tips for upgrading to Windows 10 now?
=> upgrading from 8.1, I'm going try keeping programmes unless advised otherwise.
Image your drive beforehand
I bit the bullet and told it to 'Download Now, Upgrade Later' ... in my case, Microsoft's definition of 'later' was a bit different from mine. The download started immediately and when it was finished it said it wanted to restart to perform the upgrade ... WTF!?
So I imaged it before I restarted, not the optimum solution.
Anyway, the upgrade was fine - all installed programs worked after upgrade, (eg. DaemonTools, DOpus, Sony Vegas, Malwarebytes AM, VPN software, etc), even ClassicStart. I don't have an AV installed apart from Microsoft's.
The only things that screwed up were file associations, it now wanted to use Edge instead of PaleMoon, Reader instead of PDF-Xchange, and a couple of others.
It also had to download a newer video driver but that was all on the hardware side of things.
