Some Windows 10 users reported that PC automatically Alt Tabs. This can be an issue because you’ll return to desktop while playing your favorite game or while working on an important project.
Here’s how one user described the problem on Microsoft Answers forum:
I purchased a new computer earlier this month, and have been noticing a strange pop-up window that will either alt-tab any game that I have open in fullscreen or will overlay anything else i have open for half a second and then automatically close before I can do anything or even tell what it is. It happens every half hour to a few hours, seemingly at random.
However, we managed to come up with a series of solutions that should fix the different causes triggering this unusual behavior.
What to do if Alt Tab keeps popping up?
1. Reconnect the keyboard
- First of all, you should try unplugging and then re-plugging back your keyboard.
- If you’re using a USB keyboard, you can do it without turning off your PC.
- In case you’re using a PS/2 keyboard, turn off your PC and then disconnect the keyboard.
2. Update keyboard and display drivers
- Press the Windows key + R on your keyboard > type devmgmt.msc in the Run box to open the Device Manager.
- Expand the Display adapters section > right click on each available device > select Update driver.
- Expand the Keyboards section > right click on the available keyboard > select Update driver.
- After the downloading and installing of the new drivers, restart your computer and see if it made any difference.
- If you don’t want to manually update your drivers, you can always use third-party tools such as TweakBit Driver Updater to update all your drivers automatically.
3. Perform a virus scan
- Press the Start button > open Settings.
- Select Update & Security.
- Choose the Windows Security tab > click Virus & threat protection.
- Select Run a new advanced scan > select Full scan > click Scan now.
- After the scan is finished, restart your computer and check to see if it fixed the issue.
Even though Windows Defender offers 100% protection from malware, you might want to try a third-party antivirus tool such as Bitdefender and scan your PC with it.
4. Run the game in Window mode or Borderless window mode
- Start the game and go to Graphics Settings.
- Set the game to run in borderless window mode.
- If the borderless screen is not an option, try running the game in window mode, it has a similar effect.
5. Disable a task in the Task Scheduler
- Right-click the Start button > select Computer Manager.
- Access the following location Task Scheduler/Task Scheduler Library/Microsoft/Office.
- Right click on OfficeBackgroundTaskHandlerRegistration and select Disable.
- After disabling this task, launch a game and see if it fixed the issue.
6. Disable Startup and Service programs
- Press the Windows key + R > type msconfig and hit Enter to run the System Configuration.
- In the System Configuration window, open the Services tab > click Disable all > select Apply.
- Then go to the Startup tab > click Open Task Manager.
- You will be prompted to the Services tab > select each app and click Disable.
- Close the Task Manager and restart your computer to see if it made any changes.
7. Update Windows
- Open Settings.
- Click Update & Security.
- Select Windows Update > click Check for updates.
- If it finds any updates, let it complete the process and restart your computer
- After rebooting your PC, check if updating Windows fixed the issue
Alternatively, you can download specific updates from the Microsoft Update Catalog website.
