Windows 10 crashing after upgrade from Win 8.1

I have a 27" iMac with a 3.4ghz i7 and 12 gigs of ram running Yosemite. Win 8.1 always ran fine on Boot Camp. No issues. I upgraded to Windows 10 and it was mess. First, I could not access many regular Windows features. I could not left click on certain features and things like the App Store were inaccessible. I found a patch online that was a path to a download that repaired those first issues. However, the install is still crashing after 5-10 minutes of boot up. I may have to reinstall or reset the machine but even then I am not sure how to do that. Should I do it through Boot Camp assistant or boot to windows, etc.

Any tips?

iMac (27-inch Mid 2011), Mac OS X (10.7.5)

Your 2011 iMac is not officially supported by Apple for Windows 10. Please see Use Windows 10 on your Mac with Boot Camp - Apple Support . You will run into driver issues and will have to find generic drivers or use the older drivers and re-install them with Administrative privileges in emulation mode.

Thanks for pointing out the embarrassingly obvious. I suppose I should have checked that first!! Wow. So... How do I revert back to 8.1 now that it's been over 30 days? I have an OEM disk.

Do you want to consider re-installatin of W8.1? I assume you have a backup of W8.1 before you upgraded.

I have an 8.1 disk. The part that isn't clear to me is whether I should just boot to the Win partition and insert the disk or somehow, run it through Boot Camp .

You will need to re-install W8.1 from scratch. I suggest you backup your files from W10, remove it using BC Assistant, and the use BCA fro re-install W8.1.
