Start with Fix 1 — restarting the Wacom service fixes the majority of pen-not-working cases on Windows without needing a reinstall.

Fix 1 — fastest

Restart the Wacom service

cmd.exe — run as Administrator

C:\> net stop WTabletServicePro

The WTabletServicePro service was stopped successfully.

C:\> net start WTabletServicePro

The WTabletServicePro service was started successfully.

Or via Services GUI: Win+R → services.msc → find Wacom Professional Service → right-click → Restart.

Test the pen immediately after restarting the service. If it works, you are done.

Fix 2

Unplug and replug the tablet

Disconnect the USB cable, wait 10 seconds, then reconnect. Try a different USB port — preferably a USB 2.0 port directly on the motherboard rather than a hub or USB 3.0 port. Some Wacom tablets have USB compatibility issues with certain USB 3.0 controllers.

Fix 3

Reinstall the driver

1
Uninstall current driver
Control Panel → Programs → Uninstall Wacom Tablet. Reboot.
2
Download and reinstall
Get WacomTablet_6.4.13-4.exe from the download page. Right-click → Run as administrator.
3
Reboot and test
Restart when prompted. Plug in tablet. Test pen in pressure test.

Fix 4

Check Wacom processes in Task Manager

Open Task Manager (Ctrl+Shift+Esc) and look for these Wacom processes. If any are missing, the driver installation may be incomplete:

Process	What it does	If missing
`Wacom_Tablet.exe`	Main tablet driver	Reinstall driver
`WacomDesktopCenter.exe`	Settings UI	OK if missing, settings may not open
`WTabletServicePro`	Core service (svchost)	Start via services.msc

Fix 5

Check Device Manager for errors

cmd.exe

# Open Device Manager:

C:\> devmgmt.msc

# Look under "Human Interface Devices" for:

Wacom Tablet (should have no yellow warning icon)

HID-compliant pen (should be present)

If there is a yellow warning icon: right-click → Update driver. If the device is missing entirely, try a different USB port or reinstall the driver.

FAQ

Pen not working questions

Pen works after service restart but stops again after reboot

The Wacom service startup type is not set to Automatic. Open services.msc → Wacom Professional Service → Properties → Startup type: Automatic. Click OK.

Pen works as mouse but tilt and pressure do not work

This means Windows is detecting the tablet as a generic HID device, not a Wacom tablet. The Wacom driver is not running correctly. Restart the Wacom service or reinstall the driver.

Pen stopped working after a Windows Update

Uninstall and reinstall the driver. Windows updates sometimes replace or corrupt USB driver entries for Wacom tablets. Also check Device Manager for any yellow warning icons under Human Interface Devices.
