    How to Refresh or Reset Windows 8 without an Installation Disk

    information   Information
    You may already know that Windows 8 Refresh/Reset needs an Installation USB/DVD to be connected, except if you upgrade to Windows 8 from Upgrade Assistant.

    It can be very annoying when all of a sudden your computer is not working properly while you are travelling, away from your Install Disk.

    This tutorial will show you how to be able to refresh or reset Windows 8 without an installation disk.

    To get started, you will need:
    -Install.wim file from Windows 8 Install Disk
    -Time
    -Windows 8 Computer.


    warning   Warning
    If you already set a custom refresh image, then it is recommended to not do this tutorial. By using a default install.wim file, any 3rd Party programs will be uninstalled.



    Note   Note
    Substitute C: with the drive where Windows is installed.



    1. On the C: drive, create a new folder named Refresh. If prompted, click/tap on Continue.

    Nice option!

    Useful when we don't have USB's or DVD drive around.

    C:\Windows\System32\Recovery\ReAgent.xml


    I think it may revert if we copy this xml file before changing to custom location and replace it back later in the same folder.

    How about deleting it?

    Sorry if I'm adding a silly post maybe, but does it appear on the boot menu by chance?
    Than we can remove it from msconfig by deleting its entry.

    If I've created a Custom Refresh Image (which can't be used to Reset the PC) but want to also have something prepared in the case of a Reset, would this still work? Or would it mess up Custom Refresh?
