    In my computer's registry there was no key named "system" under HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoft; I only found one under …MicrosoftWindows. Is this a mistake in the above article or do I have to create a new "system" key under Microsoft?

    Neither their suggested ‘solutions’ solved the problem. How can Microsoft be so BAD at understanding, much less supporting THEIR product? I am still unable to change from weekly to monthly backups. Buy a clue.

    I tried the registry fix, but BU still told me Internal error 0x80070057.

    So I'm stuck using the fix (replacing [,] with [.] systemwide).

    Using w7 Ultimate SP1 64b Se/Sv on a C2D E8400, if that's of any relevance.

    This error is really irritating

    Didn't find System in the registry. But then found: reset the national settings of numbers and language.

    The Fix it did not work for me … until I rebooted, after which the backup worked just fine. Might want to mention the need to reboot in KB982736.

    Since this folder doesn't exist, HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftSystem, I tried these instead, each at a time:



    But I still get the error message !

    Testar Fix-it, men inte heller det fungerar. (Den tycks skapa HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftSystem)

    Men samma felmeddelande !

    I used the fix-it offered on the page, rebooted, but the error persists.  🙁

    I am now running without option to backup for quite some time, very annoying.

    As the above comments: first changed ‘,’into ‘.’ with no effect. FixIt didn’t work either.
    what is the solution?
