The Tablet Mode toggle may be greyed out because Windows 10 does not detect your device as a tablet or 2-in-1, especially on standard laptops without detachable keyboards or 360-degree hinges. 2. To force-enable Tablet Mode on non-tablet devices, modify the registry by creating or setting the ExplorerPenSupportV2 DWORD value to 1 under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PenTeam and restart the computer. 3. On Windows 10 Pro or Enterprise, check Group Policy settings by opening gpedit.msc, navigating to Computer Configuration > Administrative Templates > System > Tablet PC, and ensuring policies like "Turn off tablet mode" are set to Disabled or Not Configured. 4. Update or reinstall touchscreen and display drivers via Device Manager or download the latest drivers from the manufacturer’s website to ensure proper hardware detection. 5. Run the built-in Power and Windows Store Apps troubleshooters via Settings > Update & Security > Troubleshoot to resolve underlying system issues. 6. If all else fails, your device may lack the required hardware—such as a touchscreen, accelerometer, or convertible design—intended for Tablet Mode, meaning the restriction is by design and full functionality may not be achievable even with workarounds. The greyed-out toggle is typically due to hardware detection or policy settings, but can often be resolved through registry modification if touch capabilities are present.

If the Windows 10 Tablet Mode option is not working or appears greyed out, it can be frustrating—especially if you're using a 2-in-1 device or a touchscreen laptop. This issue usually stems from system settings, group policies, or hardware detection problems. Here’s how to fix it:

1. Check if Your Device is Detected as a Tablet

Windows 10 automatically enables or disables Tablet Mode based on whether it detects your device as a tablet or 2-in-1. If your device doesn’t have a built-in mechanism (like a hinge sensor), Windows may not activate the toggle.

• Go to Settings > System > Tablet mode
• If the option says "Make Windows more touch-friendly when using your device as a tablet", but the toggle is greyed out, it likely means Windows doesn’t recognize your device as convertible.

? Note: On standard laptops without detachable screens or 360-degree hinges, Microsoft often disables the Tablet Mode toggle by design.

2. Enable Tablet Mode via Registry (For Non-Tablet Devices)

If you want to force-enable Tablet Mode on a regular laptop or desktop with touch support, you can do so via the registry:

1. Press Win R, type regedit, and press Enter.
2. Navigate to:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PenTeam

3. Look for a DWORD value called ExplorerPenSupportV2. If it doesn’t exist, right-click in the right pane > New > DWORD (32-bit) Value and name it ExplorerPenSupportV2.
4. Double-click it and set its value to 1.
5. Restart your computer.

After rebooting, go back to Settings > System > Tablet mode—the toggle should now be active.

?? Warning: Editing the registry can affect system stability. Back up the registry before making changes.

3. Check Group Policy Settings (Pro/Enterprise Editions)

If you're on Windows 10 Pro or Enterprise, group policies might be restricting Tablet Mode.

1. Press Win R, type gpedit.msc, and press Enter.
2. Go to:

   Computer Configuration > Administrative Templates > System > Tablet PC

3. Look for policies like "Turn off tablet mode" or "Prevent switching to tablet mode".
4. Double-click them and set to Disabled or Not Configured.

Restart your PC afterward.

4. Update or Reinstall Display and Touch Drivers

Sometimes, outdated or corrupted touchscreen or display drivers prevent Windows from detecting tablet capabilities.

• Open Device Manager (right-click Start button > Device Manager)
• Expand Human Interface Devices and Display adapters
• Right-click on touchscreen-related entries (e.g., HID-compliant touch screen) and Update driver
• Alternatively, visit your device manufacturer’s website (e.g., Dell, HP, Lenovo) and download the latest touchscreen and system drivers.

If the touch device isn’t listed, the driver may be missing entirely.

5. Run the Windows Troubleshooter

Windows includes a built-in troubleshooter for power and system issues that can sometimes resolve underlying problems:

• Go to Settings > Update & Security > Troubleshoot
• Run the Power troubleshooter and Windows Store Apps troubleshooter
• Reboot and check Tablet Mode again

6. Consider Your Hardware Limitations

If none of the above works, it might simply be that your device isn’t designed to support Tablet Mode. Microsoft restricts the feature on devices without:

• Detachable keyboards
• 360-degree hinges
• Touchscreen accelerometer/sensor input

In such cases, even if you force it via registry, the full tablet experience (like auto-hiding taskbar or touch-optimized Start menu) may not work as expected.

Bottom line: The greyed-out Tablet Mode toggle is usually due to hardware detection or policy restrictions. Use the registry trick to enable it manually—if your device has a touchscreen, you’ll at least get a more touch-friendly interface. Otherwise, the feature may not be intended for your device type.

Basically, it's not broken—it's by design, unless you tweak it.
