Stop Windows Mixed Reality from starting: the FirstRunSucceeded value

Short answer

Updated

Windows Mixed Reality is the headset platform Microsoft has since retired. FirstRunSucceeded set to 0 marks its first run as not done, so its shell does not start by itself. In the registry it sets FirstRunSucceeded to 0 under HKLM\SOFTWARE\Microsoft\Holographic.

What it does

Windows Mixed Reality is the headset platform Microsoft has since retired. FirstRunSucceeded set to 0 marks its first run as not done, so its shell does not start by itself.

In the app the switch is called "Disable Windows Mixed Reality", described there as: Marks the Mixed Reality first run as not done, so its shell does not start on its own.

When it helps, and when it hurts

When it helps

  • Older Windows 10 and 11 versions that still carry the Mixed Reality components.

When it hurts

  • Nothing, unless you own a Windows Mixed Reality headset.

What it writes

Exactly what the switch changes, read from the app's source. Switching it off is what the app writes when you turn the tweak off again.

The same change by hand

You do not need the app for this one. These commands make the changes from the table above. Run them in a Command Prompt opened as administrator, and make a restore point first.

Make the change · CMD
reg add "HKLM\SOFTWARE\Microsoft\Holographic" /v "FirstRunSucceeded" /t REG_DWORD /d 0 /f
Put it back · CMD
reg add "HKLM\SOFTWARE\Microsoft\Holographic" /v "FirstRunSucceeded" /t REG_DWORD /d 1 /f
See what it is set to now · CMD
reg query "HKLM\SOFTWARE\Microsoft\Holographic" /v "FirstRunSucceeded"

How to undo it

In the app: Yes

Switching it off sets a standard Windows value, which may not be exactly how you had it.

Switch the tweak off in Frozen Tweaks. It writes FirstRunSucceeded back to 1.

Changing several settings at once? The app's Make a restore point button, on every plan, makes a Windows restore point before you start.

Verdict

Harmless, and irrelevant on current Windows 11 where the feature is gone.
