Microsoft has updated PowerToys with two new tools that help control multiple Windows systems with the same keyboard/mouse and quickly preview various file types.
As its name implies, the new Mouse Without Borders utility can let users control up to four computers using a single mouse and keyboard.
To configure the utility, you have to go to Mouse Without Borders in the PowerToys Settings and generate a new security key on the main computer.
On the secondary computer, enter the security key and the name of the control computer, then click "Connect." After connecting the computers, you can seamlessly transition between them by moving the mouse cursor through the screens' edges.
"To allow Mouse Without Borders to control elevated applications or the lock screen from another computer, it's possible to run Mouse Without Borders as a service under the System account," Microsoft says.
Once toggled on via the PowerToys settings, Peek will show a preview of the currently selected file in the File Explorer app when pressing the Ctrl+Space keyboard shortcut.
