The OP is complaining because the Win10 upgrade corrupted his machine such that now, he can not go back to Win7. That sounds like a problem resulting from the Win10 upgrade to me!So I was duped into upgrading thinking I could go back to Win 7 if Win 10 was not to my liking... I tried to go back to Win 7 only to be told I'm sorry but some of the components where removed to be able to install Win 10. So you can not go back to Win 7.....
Again -- NOT true! The OP did not choose to corrupt his machine, rendering Win7 unusable. The Win10 Upgrade tool chose to do that -- TO the OP's machine., and everything complained about were things that were related to choices made, not the issues with Windows 10 itself.
Once again -- it is NOT reasonable for folks to expect that the MS upgrade is going to corrupt their machine, making it unusable. And before anyone says this is NOT happening, it DID -- to the OP. And it did, to my machine, as well. And it has also done that to hundreds of folks that have posted to the HP Support forums about their problems over the last several weeks.
So, once again, I join in with the few others on this forum and say that we need to stop bashing folks who come here for help.
