I upgraded to Windows 8.1 from Windows 8 without taking a system Image before the upgrade. And I'm pretty unhappy with the upgrade as my PC continuously keeps crashing and keeps showing some lame messages that the system had to restart for some unknown reason.

Now I'm thinking of downgrading to Windows 8. I have the Windows 8 DVD and also the product Key. Is it possible to simply put the DVD in and run the setup again? Just like installing a fresh copy of Windows 8?

I looked at many sites and all were talking about the trouble in downgrading. However, none of them mentioned whether one can just put the Windows 8 DVD and install a fresh copy of the OS.

Can someone give a clear answer whether I can downgrade using the Windows 8 DVD or I cannot?

Thank you.

If you don't think any one can install a fresh copy of the OS, how would they have ever shipped with the OS installed? – Dave Mar 7 '14 at 13:10
Can you please be more elaborate? Thanks. – Amogh Natu Mar 7 '14 at 13:11
No; There is no way to revert back to Windows 8.0 without reinstalling Windows 8.0. If thats really what you want to do boot to the installation media and install Windows 8.0. But your problems are likely caused by something else, which likely will return, if you don't understand what caused them. – Ramhound Mar 7 '14 at 13:13
Were you having problems with Windows 8 before you upgraded? If not, it could just be a driver issue. – user304064 Mar 7 '14 at 13:16
@Ramhound Well, I never faced those problems when I was using Windows 8. Only after I installed 8.1, these problems started popping up. So what you're saying is if I do a reinstall, I CAN go back to Windows 8. Am I correct? And I wonder why any one has to down vote the question. Is there anything wrong in asking a simple question.? – Amogh Natu Mar 7 '14 at 13:16

If you are asking "can I do a clean install of Windows 8?", the answer is yes.

If you are asking "can I go back to Windows 8 with all my files and configuration from my current install?", then the answer is no.

If your issues emerged only after the update, perhaps you may want to do a clean install of Windows 8.1 (please note that to use a product key of Windows 8 on a clean install of Windows 8.1 you have to do a workaround).

As mentioned before in the comments, you can also try reseting Windows 8 to factory state through this.

If the issues are not solved with a clean install, perhaps something else is wrong with your computer.
