This tutorial will show you how to open multiple instances of Registry Editor (regedit) in Windows 10 and Windows 11.

System configuration information is stored centrally in a hierarchical database called the registry. You can use Registry Editor to add and edit registry keys and values, restore the registry from a backup or to default values, and to import or export keys for reference or backup.

When you try to run regedit.exe or use Shift+regedit.exe to open more than one instance of Registry Editor, you will discover nothing happens and only one instance will open by default.

Opening more than one instance of Registry Editor can be helpful for multitasking or side by side comparison.


EXAMPLE: Registry Editor

Registry_Editor.webp




Here's How:

1 Run (Win+R) regedit.exe /m or regedit.exe -m for each separate instance of Registry Editor you want to open.

You can also create a shortcut using regedit.exe /m or regedit.exe -m that you can Pin to Taskbar, Pin to Start, add to Start menu All apps, assign a keyboard shortcut to, or move this shortcut to where you like for easy usage.

This shortcut will make it easier to open multiple instances of Registry Editor on demand.



That's it,
Shawn Brink

Thing that drives me nuts is when you do 'Find next, Find next', you pretty much have to reboot to collapse all the trees!

I just hit the back arrow to collapse the tree node I’m on.

Edit: On the keyboard, I mean.

Excellent.

It works in Windows 10 as well.

Thanks,

I use a batch file to open RegEdit at root with all branches collapsed.

:: Open RegEdit at root with all branches collapsed
:: - This works for the new instance even if a previous RegEdit instance remains open
REG ADD "HKCU\Software\Microsoft\Windows\CurrentVersion\Applets\Regedit" /v "LastKey" /d "." /f
:: I always open the Registry maximised
Start /MAX /b regedit /m

Actually, this is a simplified version of my batch file. I can also run shortcuts that pass Registry Key paths in place of the /d "." above.

One classic variation on the LastKey trick is to change the key's permission to Read-Only, so the tree is permanently collapsed every time you run RegEdit.

Yeah, that only works for the key you're on. If you do a whole slew of 'Find next, Find next' one after the other, there's trees open all over the place.

What the! I had no idea you could "lock" a Registry key like that. Thank you!
