Well if you do that don't forget to disable all the crap they will provide on windows startup (updates etc). And there are probably going to be a few adobe services kicking around (you may want to disable).

Check windows scheduled tasks as well.

I haven't got the latest adobe suite but the last one I had decided to alter data in the master boot record for copy protection purposes. Detected when I tried to install the Linux grub bootloader.

CC Photoshop running - haven't had any issues yet, but a pretty fresh install of everything...

Yes, make sure to disable these things.
No need to have them constantly running in the background...

I've always had the full Adobe suite (CS and now CC) on the same PC as Sonar.
No issues.

Yes, so far so good.  Disabled some of the extra stuff from startup and SONAR is just as solid as ever.

Creative Cloud is running all the time. No problems.

If you mean Adobe Creative Cloud, yes--I have a subscription and use it on my DAW and a laptop.  It's aggravating because it has to check in for updates and licensing constantly even when I'm not running those applications, and it hogs enough CPU to bog down the SONAR audio engine.  I'm sure there is a better way to shut it off when doing music, but for now I just disconnect my internet connection when using SONAR.

You can shut-down the Adobe CC (so it's not pinging home for updates).
