By the way, could you tell me how's the legacy hardware compatibility between 7 64 bit and 10?
I'm on a shoe-string budget at work and thus a boatfull of HP Laserjet 1150, 1010 and 1200 units. A canon LBP2900 (HP clone), an old Kyocera 1620 copier with USB support, some older Plustek scanners, older Creative Labs webcams and such.
I even have to keep a VirtualPC with XP on it for some very, very old DOS-based accounting software.
And I do enjoy my Civilization II multiplayer edition - it works on 7 64 bit - will such old things work on 10?
Is there something that won't work on 10 that works on 7 for me?
You shouldn't have any trouble getting USB and networked printers working as there is pretty good universal support for printers in 10. The HP Laserjet 1150 and 1200 have Windows 10 drivers on HP's site. That Kyocera 1620 seems to only have support from Kyocera for Windows XP. Web cams should have some generic support as well.
As for the software, if you got it to work with 7 you should be able to get it to work with 10 the same way, lots of posts out there on older Civ games with 10 where it looks like it should be possible.
As always, when dealing with stuff like this there's trial and error involved so if you setup a test machine that's how you'll know for sure.
