I have a laptop that is rarely used and I have little investment in what's loaded on it.  I understand the free Win 10 is upgrade-only - that is, install in place over 8.1.  So, a clean install isn't an option even if that's what I wanted to do - which I do not.  The existing OS came with the laptop and I don't have a re-install disk, so there's a just a little bit of discomfort in deciding to make this move.  I wanted to see if others have blazed this trail.  Looks like it should be low-risk, low-hassle, but I thought I'd ask here first.
 
As to my other machines, my DAW and my every-day home-office computer - they'll both stay at Win 7 until such machine needs to be replaced (or MS drops support of Win 7 ... or hell freezes over  ).

I did it on mine and have never been happier. Every machine is different but I did the 10 upgrade on a 7 desktop and an 8.1 laptop and have had no problems to speak of. Support for 7 will end pretty quickly as will support for 8.1. That was my reason for taking the leap in faith. If you're setting it up for audio there are a few tweaks you can do to get latency very, very low. The lowest I have experienced since using Cakewalk products since 1990!

I upgraded without issue and am happy. But like Sidroe says, every system is different.

1) You must upgrade first time around to get licensed. But after that you can wipe it and do a clean install.

2) If you clone with something like acronis true image then you've got a win7 backup. You can also roll back in theory anyway without it, but I do hope you have a backup strategy anyway.

3) Hell may freeze over if Sonar stops support for win7. It is already out of mainsteam support so MS may force their hand:

That's they only reason why I did it.

I have a Lenovo Yoga 2 laptop that I use for business purposes, and when an icon appeared telling me I could upgrade to Windows 10 I thought what the hell and went for it. So off it goes into the whole drawn out upgrade process and at the end of it all tells me that it's going to restart to complete the installation. Great! So it restarts and lo & behold....I'm still rocking Windows 8.1. Not even so much as a sorry, it just acted like nothing had happened. And every time I turn it on I get another icon proudly telling me that I can upgrade to Windows 10 if I like. Microsoft is clearly trolling me so I'm just going to ignore it from now on. What do I want to upgrade for anyway? I only use it for Quickbooks and Excel. 

8.1 to 10 worked well for me.

Do it! Win10 makes Win8.1 look like the sour fart it is! (sorry, I was never a fan) Either way, Windows 10 is a true fresh breath of air in the Windows camp. No issues here.

8.1 --> 10 no issues here :)

General concensus------JUST DO IT!!!!!         Lol!
