All manual changes to the Windows Registry can be completed via Registry Editor, a tool included in all versions of Windows.

Registry Editor lets you view, create, and modify the registry keys and registry values that make up the entire Windows Registry.

Unfortunately, there's no shortcut for the tool in the Start Menu or on the Apps screen, meaning you'll have to open Registry Editor by executing it from a command line. Don't worry, though, it's not at all hard to do.

Follow these easy steps to open Registry Editor:

Note: You can open Registry Editor this way in any version of Windows that utilizes the registry, including Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP.

Time Required: It usually just takes a few seconds to open Registry Editor in any version of Windows.

    1. If you've used Registry Editor before, it'll open up to the same location you were working in last time. If that happens, and you don't want to work with the keys or values at that location, just continue to minimize the registry keys until you've reached the top level, listing the various registry hives.
    2. Tip: You can minimize or expand registry keys by clicking or tapping the small > icon next to the key. In Windows XP, the + icon is used instead.

    1. Important: Considering the impact that the registry has on your Windows-based computer, I highly recommend that you back up the registry, either the whole thing or even just the areas you're working in, before you do anything.
