All my legacy programs that ran under Windows 7 run just fine under W10 after I converted, but I don't have that program, and all my programs from office 365 to various graphic and publishing programs are newer than her Printmaster. We keep getting the notices to upgrade to W10, but I am concerned it will leave her beloved program in the dust. It is running in Windows 7 on an i-3 processor (64-bit), which again, does everything she needs. She can use it to just about its maximum utility.
