Have you recently taken up the free upgrade to Windows 10 ?
Experienced, printer not working, music files dissapeared,or mysteriously jumping, other programs giving problems ?

You are not alone. I assumed it was due to my lack of computer skills.
But no, of the people I discussed this with, the last one, who’s husband is a computer programmer, have all had similar experiences.

To date I hav’nt seen any notifications or updates from Windows, addressing these gliches.

please contact Windows through their “feedback” facilities, expressing your concerns & dissatisfaction & hopefully they will come up with the neccessary repairs
