Windows 10: Is the registry (regedit) "live?"

Say I have regedit open and I make some changes on my system that affect the registry. Does regedit know about those changes, or do I have to stop and restart regedit?

Regedit Values

Hey AlindApoorva!

You can view the name and contents of any Windows registry by:

• Opening Windows Run (Windows key + R)
• Typing "regedit" into it and pressing enter.
• The sidebar will contain a list of practically every registry available in Windows. You can browse this directory, and then double-click the registries that appear in the main pane to view and edit their values.

In the list, click Restart, and then click OK.

Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on your computer.
Notes

To open Registry Editor, click Start, click Run, type regedit, and then click OK.
Choosing Last Known Good Configuration provides a way to recover from problems such as a newly added driver that may be incorrect for your hardware. It does not solve problems caused by corrupted or missing drivers or files.
When you choose Last Known Good Configuration, Windows restores information in registry key HKLM\System\CurrentControlSet only. Any changes you have made in other registry keys remain.

 

How to fix/restore regedit to default?

Hello. I need help how to restore regedit back to its default settings.

I didn't know registry editor is very sensitive that a small change can have huge impact on my computer's functionality.

So here's what happened, I was trying to fix a different issue (can't run a specific .exe file) when I bumped into one of the suggested fix (making some small change in regedit)

So I was trying to follow step from: https://support.microsoft.com/en-ph/help/2688326/can-t-open-exe-files-in-windows-7-or-windows-vista

[*]Click the Startbutton and type regedit in the Search box
[*]Right-click Regedit.exe in the returned list and click Run as administrator
[*]Browse to the following registry key:

HKEY_CLASSES_ROOT\.exe

[*]With .exe selected, right-click (Default) and click Modify…
[*]Change the Value data: to exefile
[*]Browse to and then click on the following registry key:

HKEY_CLASSES_ROOT\exefile

[*]With exefileselected, right-click (Default) and click Modify…
[*]Change the Value data: to "%1" %* (THIS IS WHERE I MADE A MISTAKE)
[*]Browse to and then click on the following registry key:

KEY_CLASSES_ROOT\exefile\shell\open

[*]With openselected, right-click (Default) and click Modify…
[*]Change the Value data: to "%1" %*
[*]Close the Registry Editor and restart your PC

Now, I can't open regedit.exe or any .exe files.

I'm getting the error: Windows can't opent this file

Your help would be greatly appreciated!
