Locking your Windows 10 PC isn’t just about being paranoid; it’s a quick way to keep your stuff safe when you’re stepping away, even if it’s just for a minute. Sometimes, people overlook how easy it is to lock the device—like a couple of keystrokes or a few clicks—and that could save some headaches if someone else walks up behind you. But here’s the thing: Windows offers several ways to do it, and not everyone knows all of them, especially the more hidden tricks or shortcuts. If you’ve ever come back to find someone snooping at your screen or wanted a fast way to secure your info, this list should cover all the main options and some neat tips to keep your session locked down.
How to Lock Your Windows 10 Computer — Tried and True Methods
Use the Keyboard Shortcut – Fastest Lock
This is the classic move—press Windows + L. It’s kind of weird how instinctive it is once you know, but on some setups, it feels like a little trick of magic because it locks everything instantly. No fuss, no navigating menus—just one keystroke combo, and you’re safe. Worth mentioning: sometimes, if there’s a background process or a weird glitch, this shortcut might not work immediately. On those days, you might need to try an alternative.
When it works, expect your screen to switch to the lock screen with your password prompt. Simple as that. A handy tip: if you have a touchscreen or a gaming keyboard, this shortcut still applies, so don’t forget it.
Lock from the Start Menu — The Mouse Route
Click Start, then your user icon (that tiny avatar at the top or left), and choose Lock. Yeah, it’s straightforward, but sometimes people forget that this option is always there—especially if they’re used to shortcuts. If you’re mostly a mouse person, this is reliable. Just a few clicks, and the job is done. On some Windows setups, this might lag a second if your PC is busy, but overall, it’s pretty stable.
Use Ctrl + Alt + Delete — The Old-School Method
This combo has been around forever. Press Ctrl + Alt + Delete all at once, then choose Lock. It’s a bit more clunky, but it works in almost every situation. The reason people still do this? Sometimes, keyboard shortcuts get disabled in certain apps or during remote sessions, so hitting this is a dependable fallback. Plus, it opens a menu where you can switch users, sign out, or lock, giving you more options.
On some machines, this might feel a bit laggy or have a delay, especially if your system is strained. But most times, it’s solid.
Create a Desktop Lock Shortcut — DIY To The Rescue
Right-click on your desktop, pick New > Shortcut. In the box, type rundll32.exe user32.dll, LockWorkStation. Hit Next, give it a name like “Lock PC, ” and press Finish. Now, there’s a button right on your desktop that’s basically a lock switch—super handy for those who like to customize their workspace.
Just a heads up: sometimes, depending on your permissions or system policies, creating this shortcut might need admin rights. Also, on certain setups, maybe it doesn’t work immediately, but overall, it’s a neat little trick.
Lock Using the Screen Saver Settings — For the Lazy Days
Head over to Settings > Personalization > Lock screen. On the side menu, click Screen saver settings (at the bottom).Check On resume, display logon screen. This way, when your screen saver kicks in after your chosen inactivity time, it’ll ask for your password when you wake it back up. This method is perfect if you wanna set a timeout and forget about it—Windows will do the locking for you. Keep in mind, on some setups, you might need to set the screen saver to a blank screen or a photo, then check that box.
On my work machine, it’s hit-or-miss; sometimes it locks smoothly, other times, I have to wake the screen from the power button. Still, it’s good to know this option exists if you want a more “set and forget” approach.
After trying out these ways, your PC should be locked and require a password to get back in. That’s the main goal—keeping prying eyes or casual glanceers out.
Tips for Locking Your Windows 10 Computer
- Set up two-factor authentication if possible—extra layer of security.
- Shorten your screen saver timeout to something like 5 minutes or less, so you’re not leaving your info exposed too long.
- Always lock your PC when stepping away, even if just for a minute—trust me, it’s worth it.
- Consider tracking software or remote lock tools if you’re worried about theft or lost devices.
- Make sure your password is strong, especially if you’re leaving the computer locked overnight or for long periods.
Frequently Asked Questions
Why should I bother locking my Windows 10 PC?
Because it keeps your emails, files, and personal info safe from curious coworkers, friends, or strangers. Seems obvious, but a lot of folks forget it’s the easiest security step.
Can I change the shortcut for locking my computer?
Windows doesn’t natively let you reassign the Windows + L shortcut, but creating your own desktop shortcut with rundll32.exe user32.dll, LockWorkStation is a good workaround. You can put that shortcut on your taskbar or desktop for quick access.
What if I forget my password after locking?
You’ll need to reset it via your Microsoft account or use a password reset disk if you’ve set one up already. Not fun, but that’s the security game.
Is locking the same as signing out?
Nope. Locking keeps your session active—apps stay open, you’re just temporarily hidden behind the login screen. Logging out closes everything and ends your session.
Can I lock my PC remotely?
Yes, with tools like Microsoft Intune or even through some remote desktop apps, you can lock it remotely, which is handy if your PC is lost or stolen. But that’s a whole topic for another day.

- Lock via the Start menu if you’re avoiding shortcuts.
