I did the free update to Windows 10 from the Icon on my desktop that told me my system was Window 10 compatible. After the update I went to watch you tube audio training videos and got either green screens or error messages. It turns out that my AMD APU A6-3620- Radeon HD6530D GPU is not compatible with Windows 10 even though Microsoft said it was.
I rolled back to Windows 7 because AMD has no intention of updating the driver for that GPU. All is back to normal. This is a 5 year old computer.

I have had plenty of people say how nice Windows 10 looks. And yes it does boot faster. Its the future and the support it will get is going to be much better than in the past for older OSs. 
 
If you have driver problems try Vista drivers or Win 7 drivers. Windows 10 is not as sensitive to drivers as 7 and 8 were.
 
 
Plus its free now but it wont be free forever. 
  

Unfortunately I am not one of the 'plenty' It looks hideous
 
On the 3 machines I installed on, I noticed no considerable/noticeable difference in boot speed, no I did not time it, but I can't recall thinking, 'wow that boots fast'. Plus I can't recall ever thinking 'gee I wish my PC would boot faster' It's a non issue to me, never had a problem with it, who cares if it did take an extra 10 seconds, it's certainly not a selling point to me, it doesn't even rate.
 
M-Audio Delta 1010 (perhaps others of the Delta family) are reported NOT to work in Windows 10, Windows 8 was also apparently a bust. Zero hope of new drivers. Yes I could get new sound cards, that's not the issue, I like the 1010's. One day I will have to move on, that day is not yet.
 
Free . . .  well . . .  you get what you pay for . . . cost is not an issue.
 
[Edit] When I went to Windows 7 from XP, there wasn't a moment I thought about going back to XP, as soon as I booted up Windows 7, XP was dead. When I upgraded from Windows 7 to Windows 10, apart from the initial pretty picture/s at the login screen or whatever it was, there wasn't one moment I didn't want to go back to Windows 7, but I persevered for a couple of weeks, thinking that it may grow on me, it didn't. It may well be the best thing since sliced bread under that hideous exterior, I just can't bare to look at it to be honest, hideous is not a strong enough word. I just don't have an issue with what I am using now, and can't see that changing for a few years to come. When cake officially drop Windows 7 support, chances are Sonar will continue to function as expected for some time, plus one can always stay at whatever iteration of Platinum they are at, or just drop it, REAPER will continue to support Windows 7 for years to come, as they are still supporting XP to this day. The sky is not falling, there is no rush, there is no need or apparent reason to change at this time, unless you want to

Not surprising since, sadly, M-Audio is garbage when it comes to drivers. I had a Delta 1010 back in the Windows 98 days. Man did that thing have good sound, but poor software. When Windows 2000 came out, M-Audio said they were never going to support it because "WDM introduces a 30ms delay which is unacceptable for pro audio." Of course that's not the case with WMD/KS mode, which Cakewalk made me aware of. I, and I'm sure many others, contacted them and told them this. Eventually Windows 2000 drivers came out... that supported only 2 of the 10 channels. They said "That's all WDM can do, it is an OS limitation." That didn't sound right so I e-mailed MS, not really expecting anything, but I think they were sufficiently surprised with how dumb the question was that they answered and linked the relevant technet docs about how WDM does mluti-channel audio. I sent those to M-Audio (no response) and eventually months later proper drivers came out.
 
...well proper except that they didn't support interrupt sharing, which is mandatory as part of the PCI spec and so would have a problem depending on how you set your motherboard up.
 
I finally got tired of it and sold the thing. Very sad, since as I said, just top notch audio section.

Its funny you keep referring to Reaper when as far as looks go it is the butt ugliest DAW on the market. Yet Windows 10 is a very beautiful OS.

Ahhh . . . but have you looked into the custom  themes available ?  I think not ?
 
And as they say "beauty is in the eye of the beholder"

My concern is for the many VST's I have and how many manufactures state compatibility with 7, 8, 8.1 but no mention of 10. I just bought Xpander!2 the other day and no mention of 10 compatibility.
 
Has anyone experienced issues with their VST's not being compatible with 10?

No. 
 
To be a little more forthcoming. Win 10 is not going to require any special coding for programs to run. It is far more insensitive to drivers version and it really doesn't care much about what programs you run. The development of Win 10 was very open and many took part in the preview program. This was not about getting it sooner but rather having some voice in how it progressed. When a problem came up MS was quick to fix it. It was tested on a lot more computers than any past version before the final version was released. There is no reason to expect trouble with it or problems due to it. 
 
Right now I have all my gear working well with it even though I do not have specific drivers for some gear for Win 10. Its fine using older drivers if there are no updated ones. 
 
We shouldn't be looking for trouble where there is none. It works well on just about any gear you throw at it. No hoops to go through. No angst to bother you. Its a fine OS that will work on your system with your gear. 

M.S. is likely trying the herd us all into one pen so they can then "update" Windows to a play to use model. That's why it is free kiddos. Your C drive and the setup you have going there is your toy for your use whenever you see fit - keep it that way  Win 10 is "license to run software" run amok.
 
Imagine if your Tonka toys went rental, you would have thrown a fit!
 
The start menu isn't even that great.
I'm sticking with 7 until kingdom come.
 

The thing about the privacy concerns with Windows 10 is that if you think they aren't already tracking everything on previous versions, then you are being naive.  They've just been more honest in the Windows 10 agreement.

The advantages to the upgrade are legion and well documented. It's just a superior technology to 8 and 8.1 and much better that 7, particularly with multi-threaded apps. But that UI!
 
I get that the Windows 10 design esthetic is different. There's much less window dressing and the icon styles are flat rather than 3d, as are the window borders. The style is intended to de-clutter the user experience by emphasizing content over distracting eye candy. Some people love it, some people hate it, but most people I would guess are like me; they shrug and get on with things. After all, things are structurally pretty much the same as they ever were. I spent essentially zero time trying to figure things out and got right to work.
 
With experience, the thoughtful user develops a deeper understanding of what the design actually achieves; it puts the OS into the background where it belongs and puts the apps and content the user really needs at the forefront. Spending less time distracted by OS geegaws increases your productivity.
 
That's the theory anyway. The reality is that Windows 10 works pretty much like Windows 7 for all practical purposes. Visually, most of what I see in Windows 10 is the desktop background, and I can make that look like anything I want. Then there's the taskbar and window borders and occasionally the Start screen. Those are somewhat customizable but that's limited. Most of where I spend all my time, Sonar, Office and developement tools all look exactly the same.
 
In the end I saw no reason to avoid all of the advantages to the upgrade because of the lack of 3d borders and flat icons. That's just me. Then again, I felt the same way with 8 and millions of people felt otherwise.
