Before you proceed, some of you may want to create a system restore point first, so that you can revert back, if you find that the results are not what you expected.
1] Run the following command in an elevated command prompt, to run the System File Checker.
sfc /scannow
Restart after the scan is over and see if it helped.
2] Repair Windows Image. Open an elevated CMD copy-paste the following and hit Enter
Dism /Online /Cleanup-Image /RestoreHealth
Restart after the scan is over and see if it helped.
3] Make Start full screen and back. Enable Tablet Mode and Start Screen and then go back. See if this toggling has helped.
4] Open an elevated PowerShell window type the following and press Enter:
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
To open an elevated PowerShell prompt, type PowerShell in taskbar Search, and in the result ‘Windows Powershell’ which appears, right-click and select Run as administrator.
NOTE: You may do this, to open a Command Prompt or Powershell window. Press Ctrl+Shift+Esc to open the Task Manager. Click on File menu > Run new task. To open a command prompt window, type cmd. To open a PowerShell prompt, type powershell. Remember to check the Create this task with administrative privileges check-box. Then hit Enter.
