What it does

Windows downloads optional language features, such as speech, handwriting and text to speech, on its own through a scheduled task. This tweak disables that task.

When it helps, and when it hurts

When it helps

Avoiding a background download and install that starts when it suits Windows, not you.

When it hurts

After adding a display language, its speech and handwriting parts are not fetched automatically. You add them in Settings.

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.

This tweak has no fixed list of registry values to print here: it works through a driver's own settings, scheduled tasks or values that differ from PC to PC (per device, per adapter or per installed game). The app reads what your PC has and changes only that.

How to undo it

In the app: Yes

Switching it off turns the two language feature tasks back on, as Windows ships them.

Switch the tweak off in Frozen Tweaks.

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

Safe. It only matters if Windows was installing these while you played.
