Finally, you will be able to reset the Start menu layout in Windows 10. Do the following.

1. Enable the built-in Administrator account in Windows 10.

   Replace the <user name> portion with the name of the user whose Start Menu layout you need to reset. In my case, the username is "winaero": Here, delete the Database folder:

5. Now, go to the following folder:

   C:\Users\<user name>\AppData\Local\TileDataLayer

   Replace the <user name> portion with the name of the local account which you created before. In my case, the username is "mylocalaccount":

7. Now, sign out from the Administrator account.
8. Sign in with your regular account. You will see that the Start menu layout was changed from your customized one to defaults.

The Start screen in Windows 10 keeps almost all data related to pinned apps and tiles in the following file:

%LocalAppData%\Microsoft\Windows\appsFolder.itemdata-ms

To locate the appsFolder.itemdata-ms file, you may also use the following trick:

• Press Win + R keys together on your keyboard. The "Run" dialog will be displayed on the screen.
• Type the following:

  shell:Local AppData

  Tip: You can get the full list of shell commands from here: The full list of shell commands.

To reset the Start screen layout in Windows 10, you need to perform the following simple steps.

1. Exit Explorer.
2. Delete the appsFolder.itemdata-ms file.
3. Run Explorer again.

Let's see how it can be done.

Exit Explorer

Before you leave the Explorer shell, open an elevated command prompt and type:

cd /d %LocalAppData%\Microsoft\Windows\

Do not close this window, leave it open, you will need it a bit later.

To exit the Explorer shell, use the secret "Exit Explorer" context (right-click) menu item on the Taskbar or Start Menu, which is described in the following article: "How to properly restart the Explorer shell in Windows".

Your Desktop wallpaper and the taskbar will disappear when you exit Explorer:

Delete the appsFolder.itemdata-ms file

Now type the following at the command prompt (you may need to switch to command prompt using Alt+Tab):

del appsfolder.itemdata-ms
del appsfolder.itemdata-ms.bak

This will remove appsFolder.itemdata-ms and appsfolder.itemdata-ms.bak files from your hard drive. Note that these commands do not produce any message, they are completely silent. Now you can close the elevated command prompt window.

Run Explorer again

Press Ctrl + Shift + Esc shortcut keys together on your keyboard. It will open the Task Manager. Choose File -> Run new task and type explorer in the 'Create new task' dialog. Click OK or press Enter:

That's it. The Taskbar will reappear. If you switch to the Start screen now, you will see that its layout has been reset. Actually, Windows 8 also allows you to do this trick.
