Since I started using Sonar Platinum on Windows 10 I've had a lot of Sonar crashs, systematically crashes, and errors along with certain plugins not working or working right.

I also see a lot of other users reporting crashes.

Can't help but wonder if Windows 10 is the culpret.

I have been on Windows 10 for well over a year and I would say it is the most stable system I have ever had. 
 
I think you need to provide more details about your projects along with the spec of you machine and then some one on here might be able to help you.  

Giving us a lot more information about your machines specifications (Ram, CPU, driver mode etc) and which plugins would go along way.  Also, are you using all 64bit plugins, (if you're running Windows 10 64bit)?

I am sure there are plenty of people here who have the latest Sonar Platinum with Windows 10 who have had no issues what-so-ever.

My crashes are so many & varied that a detailed description of each and every one would be impossible before the lifetime updates ran out. :) However, at least 2 of them were sent to Cakewalk thru the automated crash dump system.

Some crash Sonar.
Some crash Windows.
Some plugs don't work.
Some plugs fail to register tho they are registered.

Before windows 10 I had no such crashes, Not this many or so frequently. Most are likely a problem with win10 & plugins not getting along.

Then again, I could have a bad memory chip.

do you have a win7/win8 full backup you could roll back to? if so, I'd back up the current win10 state (to have the latest version backed up), roll back to win 7/8 to see if it was indeed more stable (if not, it is clearly a hardware problem, some component gone south) ... if it works stable on win7/8 consider going through the upgrade process one more time to basically reinstall all of win10 to rule out that something went wrong there ...

Are you running a "clean"win 10  installation on your system ?

It's a new laptop with win10 preinstalled so I have nothing to roll back to.

what about your soundcard ? are you using the SoundBlaster 3Di ?
if so have you checked for an update ? I don't condone using onboard soundcard at all but if you are,
make sure you have the latest version/update.

I've been having plenty of Windows 10 issues...
...and I just did the upgrade from Win7 Pro x64 to Win 10 Pro x64 - not a clean install.

Most of the issues are driver related.
Some crashes point to the Universal Audio plugins.

Are the plugins you refer to from UA by chance?

On UA's support site, they are recommending that you do NOT update to Win 10 Anniversary, as
their drivers do not comply with the latest Windows 10 updates...
...go figure.

Would have been nice to know before Microsoft was kind enough to do the update anyway...

I have crashes when:
 
I mix some 32-bit plugins with 64bit plugins. I'm on Windows 10 x64. Solution: replace all free 32bit effects with 64bit effects...
 
I try to do something with an altered audio clip before I bounce it to finalize the changes (particularly when stretching audio, sometimes if I process a clip with an effect, often when using region effects.) Solution: remember to bounce audio clips, more easily said than done.
 
A background process like an antivirus program starts doing something, or I open a browser window that wants to share my sound device. Solution: disable my network adapter and antivirus when working on a big project.
