5 Ways To Fix IMPERSONATING_WORKER_THREAD

Here’s what you can do:

Turn off Fast Startup

Fast Startup is a Windows feature that allows your system to boot up faster by putting your computer into a hibernation state when you shut it down. However, it can sometimes cause system errors like IMPERSONATING_WORKER_THREAD. Here’s how to disable it:

1. Press the Windows icon + X, then select Power Options.

2. Tap Additional Power Settings on the top right.

3. On the left panel, click Choose what the power buttons do.

4. Click on Change settings that are currently unavailable.

5. Under the Shutdown settings section, uncheck the box next to Turn on fast startup. Then click Save Changes and restart your computer.

Scan Device Performance and Health

Windows has built-in diagnostic tools to assess your system’s overall health. A Device Performance and Health scan can help detect and fix underlying issues contributing to the IMPERSONATING_WORKER_THREAD error. Here are the steps to follow:

1. Press Windows + I to open Settings. Click Update & Security.

2. Select Windows Security from the left pane. In the right-hand panel, click Device Performance & health.

3. Check your Health report. If any issues are found, follow the recommended actions to resolve them.

Run Windows Defender Offline

Malware infections can sometimes interfere with worker threads, leading to errors such as IMPERSONATING_WORKER_THREAD. You can run a Windows Defender Offline scan to identify and remove persistent malware. Follow the steps below:

1. Press Windows + I to open Settings and click Update & Security.

2. Choose Windows Security from the left panel, then tap Virus & threat protection. 

3. Click on Scan options.

4. Scroll down and select Microsoft Defender Offline scan, then tap Scan Now. 

Your PC will restart, and Windows Defender will run a deep scan for malware before booting.

Uninstall Recently Installed Software

If the IMPERSONATING_WORKER_THREAD error began after installing new software or drivers, that could be the cause. Uninstalling it may restore system stability.

1. Press Windows + X, then select Apps and Features.

2. Scroll down and find the recently installed program. Click on it and choose Uninstall.

After uninstalling, restart your system to see if the error has been resolved.

Run System Restore

If none of the above steps work, try using System Restore to roll back your system to a point before the error. This can undo recent changes to system files, drivers, and settings. Here’s how:

1. Press Windows + S, type System Restore, and hit Open.

2. Click System Restore.

3. Choose a restore point created before the error started and click Next.
