You can use Windows without a Windows-logo key. Press Ctrl + Esc to open Start, use the Start button’s menu for Run, or open display settings with the mouse. If you want a spare key to act like a Windows key, PowerToys Keyboard Manager can help while it is running.

Quick alternatives without installing anything
| What you need | Alternative |
|---|---|
| Open Start | Press Ctrl + Esc or click Start. |
| Open Run, normally Windows + R | Right-click Start and choose Run. |
| Extend a second display | Open Settings > System > Display and choose the multiple-display option. |
| Lock the PC | Press Ctrl + Alt + Delete and choose Lock. |
| Open another app window | Use its New window command or Shift-click a supported taskbar app. |
Ctrl + Esc opens Start; it does not turn Ctrl into a Windows key for every other shortcut. For more window options, see our guide to opening the same app more than once.
Use the On-Screen Keyboard temporarily
Search Start for On-Screen Keyboard, or open the keyboard accessibility settings with the mouse. Microsoft‘s On-Screen Keyboard guide explains the controls. This gives you a visible keyboard when a physical key is missing, although a normal mouse route is often simpler for a one-off task.
Map a spare key to Windows with PowerToys
- Get Microsoft PowerToys through its official Microsoft Store or GitHub links.
- Open PowerToys and enable Keyboard Manager.
- Choose Remap a key and add a mapping.
- Select a key you rarely use, such as Right Alt only if you do not need it for your keyboard layout.
- Map it to the Windows key and save the change.
- Test opening Start and an ordinary shortcut such as Windows + E.
Read Microsoft’s Keyboard Manager documentation before choosing a key. Avoid removing a key you need to type passwords, accented characters or accessibility commands.
What the remapping cannot do
PowerToys must be running, and Keyboard Manager must remain enabled. Its remapping does not work on password screens. Administrator apps can need matching permissions, and some games handle keys differently.
Windows reserves shortcuts including Windows + L and Ctrl + Alt + Delete. Do not assume a software-mapped key can replace every system-level shortcut or a hardware-controlled Fn key. The Lock alternative in the table remains useful.
Undo the change or check a faulty keyboard
Return to Remap a key and remove that mapping to restore the key’s usual behavior. If you originally had a Windows key, check the keyboard’s gaming-mode or Win-lock control before remapping another key.
