    Double click on *.reg file does NOT change the key value in Registry

    I have a *.reg script which just modifies (overwrites) the value of a certain, existing Registry key.

    When I double click on it (similar to Win7) then a popup appears asking me if I really want to add the key.
    After clicking Ok I was informed that the key value has been added successfully.

    However when I peek into the Registry DB then the old key is still unchanged.

    Whats wrong?

    I disabled UAC completely (slider to lowest possible position) and my user is member of the Administrator group.

    Registry keys can be imported without UAC disabled.

    Antivirus can be blocking the Register edition.

    If you had regedit open before the merge, you have to refresh the view to see the results of the merge.
    If you use this command Regedit /S "Testing.reg", you do not have to refresh the view.

    Actually, either method of merging refreshes the view. I was thinking of when a setting is changed via the GUI. I'll edit my post.

    I would prefer using the REG Add command to add a Registry key.

    But when working with a .reg file via Explorer, Merge should be an option --- that's the OP's issue. But he hasn't clarified what his default verb is. Merge can get lost if someone mistakenly alters the association via Open with...

    Let's not lose track of the question
