I've installed W10 again, and I face having to go through every drive (five, though one is a storage spaces mirror) and every folder taking ownership, creating groups, creating users, and changing permissions. Last time it took a fair bit of time and effort, things didn't want to play nice.
Are there any tricks when moving to a new OS? Can I somehow move my users, groups, etc over so I can't have to change the permissions?
Good new though, Crashplan at least lets you adopt your already backed up files on a new computer.
