I haven't updated Windows 7 since I installed it. no need ... audio system only

My system had always been extremely stable, the only crash I'd encountered happened when rendering a melodyne clip. It never happened again so I regarded it as a glitch.
 
However, having installed 2017.5, I attempted to bounce an 3 minute mono audio clip and Sonar locked up (no progress bar activity followed by a white screen). I opened the task manager and saw that the memory usage for Sonar was 1.5GB and rising. By the time I decided to force closure the figure was in excess of 2.6GB.
 
I restarted my workstation, reloaded the project and repeated the bounce without issue. Not ideal, but considering how many years I've been using Sonar without incident, I guess it's hardly a major problem.
 
I'm always suspicious of W10's habit of updating itself with little or no regard to running programs. Only last month I was running a live Unity 3D presentation when Windows decided to update my graphic card drivers resulting in a major crash. In some ways, it's quite a dim witted OS.
 

Hi all,
 
I've been having dropout and glitching issues for a while now. I have win 10, and have had Sonar Platinum since day one. I get glitching with the lowest number of tracks, even sometimes with one, worse with heftier VSTs like Omnisphere. I'm running an i7 6750, with 32G RAM, so more than enough. NO amount of buffer adjustment helps.
 
The adaptive limiter is useless tbh as its so flaky. PLenty of audio drop outs too, certainly in the last 6 months or so.
 
So bad, I thought it was my interface (Komplete Audio 6). Drivers are the NI proprietary ones, not ASIO4 All.
 
On top of that, I have just entered the world of pain that is Automap. New Novation Impulse 61, lovely player, but Automap is about as automatic as a 50 year old self winding Timex.
 
I have used Cakewalk's DAWS since the early days, but I am slowly getting to the end of my tether with it.
