# Stop Windows from collecting typing and inking data: the registry values

**Short answer:** Windows builds a personal dictionary from what you type and write with a pen, and can use it to improve suggestions. These values stop the collection of typed text, handwriting and contact names. In the registry it sets RestrictImplicitInkCollection to 1 under HKCU\Software\Microsoft\InputPersonalization, and 5 more values.

## In the app

- Switch: Disable Typing and Inking Data (Security, Free, Standard)
- Undo: Yes. Switching it off puts back exactly what was there before, value for value.
- Catalog row: https://frozentweaks.com/tweaks#t-1131

## What it does

Windows builds a personal dictionary from what you type and write with a pen, and can use it to improve suggestions. These values stop the collection of typed text, handwriting and contact names.

In the app the switch is called "Disable Typing and Inking Data", described there as: Stops Windows from collecting what you type and write to personalize its dictionary.

## When it helps

- Privacy: what you type is no longer collected for personalization.

## When it hurts

- Text suggestions and handwriting recognition stop adapting to you.

## 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 |
| --- | --- | --- | --- |
| `HKCU\Software\Microsoft\InputPersonalization` | `RestrictImplicitInkCollection` | `1` | Your previous value (saved before the change, or deleted if there was none) |
| `HKCU\Software\Microsoft\InputPersonalization` | `RestrictImplicitTextCollection` | `1` | Your previous value (saved before the change, or deleted if there was none) |
| `HKCU\Software\Microsoft\InputPersonalization\TrainedDataStore` | `HarvestContacts` | `0` | Your previous value (saved before the change, or deleted if there was none) |
| `HKCU\Software\Microsoft\Personalization\Settings` | `AcceptedPrivacyPolicy` | `0` | Your previous value (saved before the change, or deleted if there was none) |
| `HKLM\SOFTWARE\Policies\Microsoft\Windows\HandwritingErrorReports` | `PreventHandwritingErrorReports` | `1` | Your previous value (saved before the change, or deleted if there was none) |
| `HKLM\SOFTWARE\Policies\Microsoft\Windows\TabletPC` | `PreventHandwritingDataSharing` | `1` | 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 "HKCU\Software\Microsoft\InputPersonalization" /v "RestrictImplicitInkCollection" /t REG_DWORD /d 1 /f
reg add "HKCU\Software\Microsoft\InputPersonalization" /v "RestrictImplicitTextCollection" /t REG_DWORD /d 1 /f
reg add "HKCU\Software\Microsoft\InputPersonalization\TrainedDataStore" /v "HarvestContacts" /t REG_DWORD /d 0 /f
reg add "HKCU\Software\Microsoft\Personalization\Settings" /v "AcceptedPrivacyPolicy" /t REG_DWORD /d 0 /f
reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows\HandwritingErrorReports" /v "PreventHandwritingErrorReports" /t REG_DWORD /d 1 /f
reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows\TabletPC" /v "PreventHandwritingDataSharing" /t REG_DWORD /d 1 /f
```

See what it is set to now:

```bat
reg query "HKCU\Software\Microsoft\InputPersonalization" /v "RestrictImplicitInkCollection"
```

## 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 privacy setting. It makes no difference to performance.
