VirtualBox is my main, it's easy to use, and has a lot of support. I sometimes use VMWare for betas, tho not that much since you can set BIOS date back in VirtualBox using commands (although it is kinda annoying). I also use PCem for older betas like Windows 1.0 DR5, Alpha and Beta and also for Chic...

Windows 98/95, they are pretty nice unless the CPU is too powerful for Windows 95 lol, but they are very nice for runnng old software (tho I'd also like to try NT 4.0).

You can run 32-bit applications on 64-bit Windows, since x86_64 IS compatible with x86. You don't need to do anything, just run the application.

Hmm I wonder if the Windows ME ISOs on WinWorld are bootable.

Yes, this is a pretty nice modification to Windows XP. It looks very nice!

Does anyone have Windows CE 1.0? (NOT the desktop software)

Agree, when I first saw Edge I thought it was a new version of Internet Explorer lol.

I think all of them work on Windows 7, they should if they work on 10.

I like both Windows and Ubuntu, I have them dual-booted in a laptop so I can use any of the two. If it's your MAIN computer, go with Windows. If it's a SECONDARY computer, maybe Ubuntu or dual-booting both.
