How to Refresh or Reset Your Windows 8 PC Without the DVD


We have already shown you how you can use the new refresh and reset features in Windows 8 instead of formatting your PC, the problem is that you are required to insert your Windows DVD every time you want to use the features. Here’s how to do it without the DVD.

Refresh or Reset Your Windows 8 PC Without the DVD

The first thing you need to do is create a new folder on the root of your primary drive and call it “Windows8Files”


Now insert your DVD into your PC, or mount the ISO File and navigate to:


Copy the install.wim file off your DVD into the Windows8Files folder we just created.


Next we need to launch and administrative command prompt, so move your mouse to the bottom left of your screen and right-click then select Command Prompt (admin) from the context menu.


Now we need to run the following command:

reagentc.exe /setosimage /path C:\Windows8Files /target C:\Windows /Index 1


Now you can refresh or reset you PC as normal, except it wont ask you to insert your DVD.

    Yes, but one still needs the DVD. No great benefit by copying over files.

    I’ve got a better idea; don’t use Windoze 8 MUTRO at all.

    I think you’re supposed to do the copying off the DVD ahead of time (i.e. right after an install). Then later when you need to reset, you won’t require the DVD.

    Xubuntu 12.x is out…. Always for free….

    Yes but thus will be great for sysadmins at an office to do ahead of time to avoid a reset and needing the cd. It would be great if 7 had this feature. Should would.make my life easier.
