# Stop Windows Mixed Reality from starting: the FirstRunSucceeded value

**Short answer:** 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.

## In the app

- Switch: Disable Windows Mixed Reality (Debloat, Free, Standard)
- Undo: Yes. Switching it off sets a standard Windows value, which may not be exactly how you had it.
- Catalog row: https://frozentweaks.com/tweaks#t-1054

## 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

- 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

Read from the app's source. "Switching it off" is what the app writes when you turn the tweak off again.

Registry values:

| Key | Value | With the tweak | Switching it off |
| --- | --- | --- | --- |
| `HKLM\SOFTWARE\Microsoft\Holographic` | `FirstRunSucceeded` | `0` | 1 |

Source: Tweaks/wmroff.hpp in the app's source, app 2.0.0, checked 2026-10-08.

## The same change by hand

Run in a Command Prompt opened as administrator. Make a restore point first.

```bat
reg add "HKLM\SOFTWARE\Microsoft\Holographic" /v "FirstRunSucceeded" /t REG_DWORD /d 0 /f
```

Put it back:

```bat
reg add "HKLM\SOFTWARE\Microsoft\Holographic" /v "FirstRunSucceeded" /t REG_DWORD /d 1 /f
```

See what it is set to now:

```bat
reg query "HKLM\SOFTWARE\Microsoft\Holographic" /v "FirstRunSucceeded"
```

## How to undo it

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