Is WRSA windows 10 ready?

It is!  The one thing we don't have yet is the browser extensions for the Edge browser, but you can continue using IE 11 or Chrome or Firefox in the meantime.

That is good to know!  Just checking the Microsoft Website reading about the features and what will be happening during the install process and it stated that if any antimalware that might not be compatible with 10 will be uninstalled and so forth!  WRSA has been for me an excellent product and will continue to use it for years to come!  One of the employees where I work at was joking to me about the version of windows and he is waiting for windows 15 to come out LOL!
 
 

Yep, as long as you make sure your WRSA is updated to the 9.0 version. That version has passed the Windows 10 certification process so you can upgrade Windows with WRSA installed and it should be seamless.

I am running WRSA on windows 10 with no issues. So you can go ahead. Only thing that changes from Windows 8.1 is that with WRSA windows explorer takes more memory which wouldnt matter if you have a RAM rich system.

We have to wait for a "fix" from Microsoft regarding that like they had done before.
