Thanks.
Double clicking produces the same result, i.e., the Notepad window with text.
And "registry editor" is not an available option in "open with."
BTW, my OS is Win XP Pro.
I want to restore a CCleaner registry backup .reg file.
When I right-click on the .reg file and select "Merge," a Notepad window opens, containing text.
What do I do with the text?
Thanks for your help.
