How to Fix ‘Someone Else Is Using This PC’ Error in Windows 10 [Tutorial]




When you ask your PC to stop or restart, Windows first checks if other Windows user accounts have active sessions. This happens if you lock your Windows session and log in with another user account before logging out.

So Windows 10 won’t load. Or maybe it starts up but crashes a lot. Either way, you need to fix the problem before you can use your laptop. If your screen is rotated, we have an easy fix for that. If the operating system is booting slower than molasses, you can also use power settings to speed up its launch. Otherwise, here are a few ways to repair Windows 10.

Several Windows users have been reaching us with questions after encountering the “Someone else is still using this PC” error whenever they try to Shut down or Restart their computer. Most affected users are reporting that the issue occurs even if they try to log in with a different user account. As it turns out, the issue is not exclusive to Windows 10 as it’s also encountered on Windows 8.1.

What’s causing the ‘Someone else is still using this PC’ error?
We investigated this particular issue by looking at various user reports and trying out different repair strategies that other affected users have recommended for this particular issue. As it turns out, several different scenarios will trigger this particular pop-up. Here’s a shortlist of potential culprits that might be responsible for the ‘Someone else is still using this PC’ error:

The issue is caused by a Sign-in Option – As it turns out, this particular issue mostly occurs due to a change inside the Sign-in Options menu that forces the machine to use the sign-in info to automatically finish setting up the device and reopen apps. If this scenario is applicable, you can resolve the issue by turning off one option inside the Sign-in Option.

The previous user is still connected – Another possibility is that the previous user that used this PC hasn’t completed the logoff procedure. This can happen due to a machine interruption or due to user preference. To fix this issue in this case, you’ll need to use Task Manager to disconnect the previous user.

Windows updates are installing the background – If you’re seeing the issue on Windows 10, chances are your OS is mistakenly thinking a different user is connected, when in fact the WU (Windows Component) is installing one or more upgrades in the background. In this case, you can avoid the error message by finishing installing the updates first.
