Alrighty, so I upgraded my brand new laptop to 10 on launch day...and for the next week I experienced numerous problems with the OS unfortunately. I was forced to revert back to 8.1, which has been behaving flawlessly.
I would like to try the upgrade to 10 again, but I have some questions/thoughts.
-If for some reason, I again experience issues with Win 10, will I once again be able to revert to 8.1? Does 10 always let you revert to 8.1 in the first month?
-To rule out any flaws in the Win 10 update download, I'd like to delete the whole thing off my computer and let it re-download the upgrade. How do I do this?
Use MediaCreationTool to create a flash drive to use to do a Clean Install of Windows 10, which will activate okay since you have already done the upgrade and activation successfully.
Windows 10 - Clean Install
Actually, one of the problems with my first attempt to upgrade is that it would never activate.
You could download the ISO from here (make sure you chose the correct version based on your W8 OS):
Tech Bench
Mount it from within W8, and do the upgrade that way. And yes, you must get an "activated upgrade" before you can clean install.
I don't know if you will still have 30 days to revert or not.
If that's true then you need to do the upgrade to 10 again.
Disable anti-virus and any firewall you might be using other than the built-in Windows Defender and Windows Firewall,.
Disconnect everything except mouse, keyboard and display (everything). For a laptop disconnect external mouse, use touchpad.
Uninstall Classic Shell or Start8 or any other Start button software.
Then follow this: Windows 10 - Upgrade Installation
If you make an image of your Windows 8 before you upgrade you are guaranteed to be able to revert back - even beyond the 30 days. I would never trust the revert option in Windows 10. Too many people have had it fail.
While I appreciate everyone's input here...we still have not addressed my two key questions.
It is supposed to. That is no guarantee that it will. Hence, the suggestion to make your own backup image of 8.1 before upgrading.On your C: drive there should be two hidden folders called something like Windows_BT$ and Windows_WS. Delete those. Also delete everything in the C:WindowsSoftwareDistributionDownload folder.
Then upgrade using the Media Creation Tool "Upgrade this PC now" option:
Windows 10
That will download a fresh copy of Windows 10 upgrade regardless of whether or not you have deleted the old traces of the upgrade.

Addressed here:
How did you do the first upgrade? The more detail you provide the better. We may be able to figure out why activation failed.
