Overview​

This script disables the synchronization of language preferences and dictionary settings across Windows devices using a Microsoft account.

By default, Windows syncs the following language-related data:

  • Language profiles 1
  • Windows Display language 1 2
  • Custom dictionary 1 2

Microsoft calls this data language preferences and dictionary 3. Windows 11 includes this in its Windows Backup feature 3.

Disabling this synchronization prevents Windows from:

  • Collecting your typing and handwriting patterns 4
  • Storing your language preferences in Microsoft servers 1
  • Creating a cloud-based user dictionary 1 2

This improves your privacy by storing language patterns and preferences only on your device, not in the cloud. This setting is recommended by organizations focused on privacy, including the French Ministry of the Interior 5.

This may also improve system performance by:

  • Reducing background network activity
  • Decreasing cloud storage usage
  • Minimizing synchronization processes
Caution

After disabling this feature, your language preferences and custom dictionary will not sync between your Windows devices. You will need to set up these preferences separately on each device.

Technical Details​

The script disables language synchronization by setting this Windows Registry value to 0: HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\SettingSync\Groups\Language!Enabled 2 5 6.

Safe for General Use
All actions in this script is recommended for all users. This is recommended for all users to improve without any noticeable impact on the system functionality.
