Key Takeaways

Run SFC And DISM Scans

The System File Checker (SFC) scan is a built-in utility that scans the Windows OS for corrupt or faulty files or data and replaces them with the correct versions. Meanwhile, the Deployment Image Servicing Management (DISM) repairs images needed by the Windows environment.

Employing these scans can help spot abnormalities in the Windows system, which could temper its smooth operation. Therefore, I executed each code in the Command Prompt to perform this method.

  1. Open CMD: Search for Command Prompt in the Windows Search Bar > Launch in Administrator Mode > Yes.
  2. Initiate Codes: Execute the following codes one after the other:
    DISM.exe /Online /Cleanup-image /Scanhealth
    DISM.exe /Online /Cleanup-image /Restorehealth
    DISM.exe /online /cleanup-image /startcomponentcleanup
    sfc /scannow

This simple fix was also recommended by an Independent Advisor in the Microsoft Community and temporarily solved the problem for a user, as it did on my end.

Disable Microsoft Office In Background

The Microsoft Office background process is known to cause multiple system glitches, like games randomly crashing or tabbing out, as various users complained about in a Reddit thread

To counter this, I disabled the background service for Microsoft Office, restarted the computer, and noted that my computer stopped tabbing out. Resort to the instructions below to disable Microsoft in the background.

  1. Open Computer Management: Right-click on the Start menu > Computer Management.

Disable Peek

The Windows Peek feature lets users view their desktop screen momentarily while working on an open window. You can access this feature by hovering the cursor over the bottom right edge of the taskbar, which provides a quick glimpse of the desktop.

However, this feature can be a nuisance when you are not gaming in full-screen mode, as accidental cursor movements over the specified area on the taskbar can trigger the desktop view unexpectedly. Use these instructions to turn off Peek on your computer.

  1. Open Advanced Settings: Launch the Control Panel > System And Security > System > Click on Advanced System Settings on the right bar of the screen.

  2. Get To Settings: In the Advanced tab, press the Settings button under Performance.
  3. Turn Off Peek: Access the Visual Effects tab > Remove the tick beside the box Enable Peek > Apply > OK.

While the above workarounds successfully eliminated the trouble, Microsoft has not given an official response on the topic, even though it is a widely-faced problem.

Lastly, if the PC keeps tabbing out for a long period, take your computer to a technician since the graphics card or other components may have a technical fault.
