Repair Install Windows 8

How to Repair Install Windows 8 and 8.1 without Losing Anything

information   Information
Windows 8 introduced the option to refresh and reset your PC to repair or reinstall Windows 8 with as needed. These new features are great for what they are intended for, but there are some drawbacks to them.

When you reset your PC, it will basically give you a clean install (retail) or factory recovery (preinstalled OEM) of Windows 8 afterwards. You will lose everything from your current Windows 8 installation.

When you refresh your PC, this basically repairs Windows 8 by reinstalling it while keeping your files, Store apps, most of your settings, etc..... However, all installed 3rd party desktop apps will be removed. If you like, you could create a custom refresh image to not lose anything, but this will require creating new custom refresh images every so often to keep it updated to not lose anything since the last image was created.


This tutorial will show you how to do a repair install (aka: in-place upgrade install) to fix your currently installed Windows 8 without losing anything. For example, desktop apps.

You must be signed in as an administrator to be able to do a repair install of Windows 8.

  • All user accounts.
  • Files in all users' C:\Users\(user-name) folders. (ex: Desktop, My Documents, My Music, etc...)

Ah, that would be why then. WMC would not be the same as the installation media.

You might see if you may be able to do this below to remove WMC, then see if you are able to do the repair install with the Keep Windows settings, personal files, and apps option.

http://www.eightforums.com/tutorials/16077-media-center-remove-go-back-windows-8-pro.html

Before doing the repair install, check to see how your installation is working. You might get lucky with the process of removing WMC fixing it.

I had changed the registry entry to Win 8 Pro earlier. Changed it to Win 8.1 Pro just now but unfortunately it's still the same. Oh well :/

Can you still do this even if you got Windows 8.1 via an update from the Windows Store? Will it still accept my Win8 product key?

Hello XypherCode,

Yes, but you would need to have Windows 8.1 installation media, and use a generic key. Afterwards change the key to your 8 key to activate.

I've updated the tutorial to help. :)

Oh by the way before I try this out. When I'm finally going to change my key in step 24, does it accept a Windows 8 "upgrade" key because that's what I have and not the key that came when you actually bought it. The one that you can get Windows 8 for about less than 50 or 40 bucks if you upgrade from Windows 7.

Thanks.

Hello Specter, and welcome to Eight Forums.

I'm downloading an ISO now, and will install it in a VM to test when it's finished to see. I'll post back with the results. :)

I was using OPTION TWO there, but it's the same.

The Windows 8.1 Update ISO still isn't available for download using that yet though. :(

Hello Vishal, and welcome to Eight Forums.

Did it have more details in the error message?

I know this is a massive thread, and I haven't read all the way through, but can someone just clarify for me what I need to do?
I have Windows 8.1 installed via 1) 8.0 DVD with product key, and then 2) upgrade to 8.1 OTA.
I need to repair my 8.1 install, but Windows keeps telling me (correctly) that my media DVD is not valid.
What do I have to do?

Hello imacken,

You would need to have the exact same installation media as what you currently have installed. That's why it's saying that your Windows 8 installation DVD will not work (invalid) with your currently installed Windows 8.1.

If this is a retail copy of Windows, then you could download a current Windows 8.1 Update ISO using Option One below with your retail product key.

Hope this helps for now. :)

Thanks a lot, Brink.
Sorry to be stupid here, but do I do Option One 1. 2. and 3. to get the ISO upgrade?
