As long as I am assured that absolutely nothing will be deleted, I guess I'll upgrade. Is there a way to revert the changes if I don't like it?

Maybe, but I doubt it.

Hell no, and I don't usually use such strong words. What little I've used the beta, it sucks compared to 7. Why would I want to downgrade to 10 if I'm using 7? I'd be very quick to switch to 10 if I had 8, but I don't so I'm in no hurry.

Honestly, the UI still sucks compared to 7. Everything's just a little bit harder than before, and just because they tried to make it simpler. Now really dumb users have it easier but I have to look longer for features I use daily. There's probably going to be a program to change the UI back but I'm not going to support MS and their new OS.

I might try it if I could switch back to 7 at any time, but from what I've heard, it sounds like you have 30 days to switch back after which it's bye bye 7. That is, sounds like the license key won't be valid for 7 anymore.

Of course I am! So excited for Win 10. :D

Still using Windows XP :p

If you have a licence key to your current OS, you can go back. If you don't then i think you're stuck with Win 10 unless you re-purchase.

I've already opted for this get Windows 10. But I'm thinking if it would still work with Bootcamp. I don't want to end up with no OS at all. :(

Yeah, I'll be upgrading. I liked Windows 8.1 quite a bit, but 10 looks to be great.

I was wondering when it would come. Can't wait to get it! I signed up as soon as I saw a Windows 10 icon in my taskbar.

Probably won't upgrade. I still have Windows 7 Home Premium, and it does everything that i need it to do.
