Hi Rob,
You will notice that I did caution folks in doing this, especially if they're using a DAW to make a living.
I think you'll find various reasons for wanting to move to windows 10. Some of us just like to stay on the bleeding edge, consequences be damned...
In my case, I'm an IT Analyst supporting over 900 systems. I consider it a personal mission to keep my skills current. When a new OS releases, I jump on it as soon as a beta is available. I've been testing Win 10 on a surface tablet, since the first beta became available. I didn't move my main workstation over until last night, as I wasn't sure if I could get the VS100 working, but based on my experience with the beta I decided to take the risk and work through any problems that may come up. Modifying the ini file and temporarily disabling driver signing is pretty low risk, imho - as long as you know what you're getting yourself into and are comfortable with the possibility of screwing something up if you don't know what you're doing.
That said - I'll say again - I wouldn't recommend anybody do this, if they depend on their DAW to make a living or can't live with any potential down-time. Myself - I just do music on the side, as one of a few different hobbies, so the risk for me was minimal. I just wanted to share my experience with others, that may want to do the same.
As for Windows 10, it has a lot of new features that I think will be appealing to many. It is after-all the last full OS Microsoft will likely ever release as it seems they are moving more the direction of android and mac os, with frequent incremental updates. Also, if you're into gaming and want to stay on the bleeding edge, there is DX12 support in Win10, but no other OS. Even if nothing supports it yet, some of us like to get an early jump on things.
I think those of us that are early adopters, are aware of the risks.
