Has anyone upgraded to Win 10 and downgraded to Win 7 and why?

I was one who couldn't wait to upgrade, based on the hype I was reading about Windows 10. When I received the my system and software met all the requirements approval from the Get Windows 10 App, I was overjoyed. So I waited and waited, each day hoping to find the upgrade in Windows Update, but it would not come. After some research, I found out that Microsoft offered Win 10 in an ISO and the wait was over.
During the wait time I started looking for an appropriate desktop background to use and found one that I liked very much. With a little modification I came up with the following I call Win 10 Colorful:

Now with precautions taken (I thought) and the ISO in hand I decided to take the leap. The upgrade from Windows 7 Home Premium seemed to go smoothly and I was a happy camper... Until the installation was complete and I had no internet due to Win 10 drivers that were not compatible with my NIC (Realtek RTL8168C (P) Family PCI-E Gigabit Ethernet NIC (NCIS 6.20)). Finally in Device Manager Win 10 had migrated the Win 7 driver which I picked from the list and my internet icon clicked "all's well). Now everything looked as if it were working until I restarted the computer and noticed a warning that Tune-up Utilities 2013 was starting in compatibility mode. Long story short, some of my hardware and software were having problems and this was causing me enough grief to decide to revert back to Win 7, which evidently Win 10 was incapable of doing. After waiting a long time for Win 7 to return all I got was a black screen with a cursor in the center and no go on reboot, basically a boat anchor.

I removed that "C" drive and installed a Seagate Barracuda 1TB and set it up as the new "C" drive upon clean slating Win 7. After the tedious process of endless updates and SP1, I finally got Win 7 and the reinstalled programs like it used to be, with the exception of my Libraries and Outlook mail. I turned the computer off and installed the old "C" drive and restarted. Win 7 picked it up as Drive F and from there it was easy to copy my libraries and Outlook data files and some other settings I needed. After making sure I had everything I needed from Drive F, I had Win 7 format it and use it as storage.
I really wasn't mad at Win 10 because it was my mistake not to make an image of Win 7 prior to the upgrade. Now my Windows 7 Home Premium is back to its glory and running better than before. I guess I will wait until the bugs are worked out with Win 10 to install it because I did like a lot of the new features.
Now after a bit of modification to my background this is what I now use!

You learn from your mistakes and believe me I did make an image of the newly clean slated Win 7.

Hello Charbroil57 personally what I do is to clone the original drive with Macrium and use the clone to upgrade. So in the event of 10 or anything else for that matter went down the toilet then I just swap the original drive back in and clean up the clone.

I did this with two machines a desktop and a laptop the desktop turned out ok but the laptop the upgrade turned into a nightmare of Microsoft wanting me to activate from a sticker I was supposedly meant to have on the box that the DVD came (??DVD I think someone fell asleep at the wheel in M$) in when in actual fact all I used was that ISO.

I know many might not e able to do it this way but it saved my sanity (and laptop) from riding into the sunset. Not that I like 10 anyway and the more I read about it and the privacy stuff in the EULA I won't be using it that much. After all it just seems like a scrubbed up version of 8 with a bit more bling

Hi,
Well seeing as 10tp testing was going on for nearly a year that would of been a better option than an early upgrade that has only been released for just over a month now,
Early birds get the worm but they also get early bugs in the upgrading process
Thanks for testing it though :)
