how can i remove a registry key without using registry editor?

Answer 1

Create a file with its extension as .reg
eg: dummytest.reg

edit it with notepad.

To remove an entire "tree" from the registry, just add a minus sign before the tree name:

REGEDIT4

[-HKEY_CURRENT_USER\DummyTree]

will remove the entire tree "DummyTree".

To remove an individual item from the registry, place the minus sign after the equal sign:

REGEDIT4

[HKEY_CURRENT_USER\DummyTree]
"ValueToBeRemoved"= -

will remove the individual value "ValueToBeRemoved" from "DummyTree".


double click the dummytest.reg file and it will be merged with the registry

Answer 2

There are several third party (non - Microsoft) programs on the market that can give you complete access to the Windows registry. However, While these may have features that allow you to do things that "regedit" (the Windows program) cannot do, you are still playing with fire if you don't know exactly what you are doing! Your question seems kind of strange. Like "How can I get in my car and drive it without starting it"? Why would you want to do that?!!!
