I accidentally left my Win7 laptop in "sleep" mode overnight and the next morning when I activated it, it was in a state of constant hard drive activity, my worst fears were realized.
Now I am more determined than ever to join the inevitable class action lawsuit against Microsoft.
My Win 8.0 desktop, my newest Windows machine, which I had willingly decided to upgrade to 8.1, then to Win10, was completely trashed last February upon completion of the win10 upgrade install.
All my most-used programs were uninstalled, disappeared : Adobe Acrobat, AutoCad, Photo editing software, MS Office 360, and a few other utilities I cant even recall offhand.
But worst of all when the "upgrade" ended, I could not access any of my external USB Drives, and attempting to resolve the problems the desktop "died" and wouldn't even boot.
Eventually I was able to coax it into booting, and am planning to transfer any important remaining data from the hard drive and get help rebuilding the i5 Desktop.
in the meantime, I rely on my older desktop to manage all my household accounts, pay bills and save records. So upgrading it to Win 10 is permanently out of the question.
The summary of my Windows 10 experience?
NEVER!!
After 25 years of Windows (I've hated Apple,) it is time to reconsider switching to Apple, if the software I need is available for it.
What a mess!
