I am thinking of upgrading Windows 10, and want to know if I have to reinstall the Creative Cloud Apps? Also, and other common issues people experienced after upgrading to Windows 10?
You will need to deactivate the current activation. Follow Sign in and sign out to activate Creative Cloud apps
Once you have win 10, you may install the CC desktop app via Creative Cloud for desktop
Compatibility reference with win 10, please see https://helpx.adobe.com/creative-cloud/kb/Windows_10_compatibility_FAQ.html
Hope that helps!
