# AITEnable 0 and DisableInventory 1: turning off Application Impact Telemetry

**Short answer:** Application Impact Telemetry and the Inventory Collector record which programs are installed and how they behave, for Microsoft's compatibility data. These policies switch both off, along with the Customer Experience Improvement Program. In the registry it sets AITEnable to 0 under HKLM\SOFTWARE\Policies\Microsoft\Windows\AppCompat, and 2 more values.

## In the app

- Switch: Disable Compatibility Telemetry (Security, Pro, Advanced)
- Undo: Yes. Switching it off puts back exactly what was there before, value for value.
- Catalog row: https://frozentweaks.com/tweaks#t-1154

## What it does

Application Impact Telemetry and the Inventory Collector record which programs are installed and how they behave, for Microsoft's compatibility data. These policies switch both off, along with the Customer Experience Improvement Program.

In the app the switch is called "Disable Compatibility Telemetry", described there as: Turns off Application Impact Telemetry, the inventory collector and the Customer Experience Program.

## When it helps

- Privacy, and less background inventory work after installing software.

## When it hurts

- Microsoft receives less compatibility data from the PC. You will not notice a difference.

## 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\Policies\Microsoft\Windows\AppCompat` | `AITEnable` | `0` | Your previous value (saved before the change, or deleted if there was none) |
| `HKLM\SOFTWARE\Policies\Microsoft\Windows\AppCompat` | `DisableInventory` | `1` | Your previous value (saved before the change, or deleted if there was none) |
| `HKLM\SOFTWARE\Policies\Microsoft\SQMClient\Windows` | `CEIPEnable` | `0` | Your previous value (saved before the change, or deleted if there was none) |

Source: Tweaks/pack_extra.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\Policies\Microsoft\Windows\AppCompat" /v "AITEnable" /t REG_DWORD /d 0 /f
reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows\AppCompat" /v "DisableInventory" /t REG_DWORD /d 1 /f
reg add "HKLM\SOFTWARE\Policies\Microsoft\SQMClient\Windows" /v "CEIPEnable" /t REG_DWORD /d 0 /f
```

See what it is set to now:

```bat
reg query "HKLM\SOFTWARE\Policies\Microsoft\Windows\AppCompat" /v "AITEnable"
```

## How to undo it

Switch the tweak off in Frozen Tweaks. The app saved what each value was before the change and writes exactly that back, or removes the value if it did not exist.

## Verdict

A safe privacy setting that pairs well with disabling the telemetry tasks.
