HDD recognized as SSD

I installed a new SATA 3 HDD in my neighbor's laptop. Ran Defraggler w/o any problems. Now upgraded their OS to Win 10, and Defraggler recognizes the HDD as an SSD instead. Why?

Long running, well known bug in DF sorry to say.

many threads on the subject.

no word from up high as to fix.

also happens in CCleaner.

both software will get it wrong then get it right then switch back depending on updates to either the OS or the software.
