Syncing apps with wireless devices

Recommendation

Depends

On a PC without wireless displays, DLNA and network printers, the block usually breaks nothing.

If an app stops finding a device on the home network, restore the original state.

Main effect

Blocking wireless device discovery

What changes

BoosterX enables a general block for Store/UWP apps on exchanging with wireless devices that have not been explicitly paired with the PC. The BoosterX description gives a visible example: an app automatically finds a wireless printer on the same network and prints to it without manual setup. The affected scenarios are automatic discovery: wireless display, DLNA receivers, printers and Wi-Fi Direct connections. After the block, apps do not see such devices until you pair them explicitly.

Exceptions and differences

This is not the same as the neighboring permissions: “Sync with devices” controls exchange with already paired devices such as a phone in “Phone Link”, and “Trusted devices” covers accessories that you have explicitly marked as trusted. Explicitly paired devices are not affected by this block. Classic Win32 programs are not subject to the block. BoosterX applies the setting in Windows 11 and modern releases of Windows 10; on very old ones it is unavailable, and the set of permission pages in “Settings” differs — check on your system.

How to verify the result

Connect a wireless display or another wireless receiver as you normally do. Apply the block and repeat the connection: automatic discovery should disappear, while explicitly paired devices should continue to work.

How to change and revert

Open “Optimization” → “Privacy” → “App permissions” → “App sync with wireless devices”, move the toggle to “On”: BoosterX will apply the block on exchange with implicitly paired wireless devices. Click “Apply”. If “Instant apply” is enabled, a separate button is not required. To revert, move the toggle to “Off” and apply the change again: BoosterX will return the default Windows state with automatic discovery of wireless devices allowed.

Confirmation

• Research on privacy policies.
• Neighboring permissions that this setting is often confused with: “Sync with devices” and “Trusted devices”.
• The affected exchange scenarios are described according to the visible BoosterX description; no public Microsoft documentation on blocking exchange with implicitly paired wireless devices to such an extent was found as of the verification date, so the statement remains without an external source.
