    Manual System Restore

    Back in the XP days we'd perform a manual system restore by booting to a "live" OS and replacing the registry hives with backups that were generated previously.

    I thought that this had gone extinct with the advent of the newer OS's until one of the techs at work tried it on a Win8 system yesterday.

    The system had a doskey exploit that put a password on the screen before the system even reached the login.
    We used a live CD, renamed 5 of the hives to .bak and then picked copies from a backup dated from 3 October
    And, viola!, it booted to the desktop!

    I'll be posting more details (and will also add it to my website) as soon as I get a bit of time! :0)
    Just wanted to post here so that others would know about it
    Jared, Corrine, JMH and 1 others say thanks for this.

    Please note if the computer/motherboard in question had UEFI or the older standard BIOS.

    Hmmm, then I find it interesting W8 allowed the tech to boot to an unfamiliar CD. Do you know if "Secure Boot" was enabled? I note it is enabled by default on factory built PCs with OEM W8 installed at the factory.

    Re: Manual System Restore

    We have a proprietary boot DVD that allows us to boot in UEFI with SecureBoot still enabled.
    We boot into a version of Windows PE that's on the DVD.
