WINDOWS 10
As I am reading issues with windows 10 I thought I would mention what I do. When I purchase a new computer I keep the old one. The old one is disconnected from the internet, so Microsoft can not automatically up date and mess up my programs. They also serve as additional back ups. Right now I have 3 Laptops. One I am working with on a daily basis, and 2 others that have older version of Windows (XP and windows 7). This has worked for me and I was able to keep older programs I cherished that no longer worked with Windows 10. Since the older ones never go on the Internet I do not worry about Microsoft's support. Just a thought. Yes my oldies are slow, but so am I.
Just less of a chance someone to snoop in it. Since your computer is acting up I would advise making a back up. Most likely your designs are in the download folder
