Unable to search or click START after upgrading to Windows 10 Home

Someone mentioned on another thread that they created a new user account, and that resolved the problem for them in the original user account as well.

Hello,

A couple of days back I upgraded to windows 10. I upgraded from Windows 7 to 10 successfully and no problems. After that today I open my laptop and I have a black screen. I move my touchpad thinking I'm going to get to the login screen but still nothing happens. I hit the power button on my laptop to shut down and it does that. I turn on my computer I'm able to get to the login screen. I put my password then I see a black screen. I have IObit Advanced SystemCare so in the corner that's what I see but the rest is black. I wait for a while nothing happens then shut off the pc. Same thing happened and then I think at the third or fourth time I turn on my computer then go to the living room and come back and it's fixed. I play Minecraft so I was doing that. I also have a touchpad issue where when I hold the keys down I can't move my mouse but I already know the solution for that and so when I go to click the start button nothing happens. I was confused and thought maybe it was just slower than normal. I clicked the search button; nothing happened. I then search up on the web "unable to click start button on windows 10" and I find a post with a solution but wasn't really for me:
---------------------------------------------------------------------------------------------------------------------------------

1. Open Windows PowerShell as Administrator
   
   1. Right click Start button
   2. Choose Command prompt (Admin)
   3. Key in Powershell in the black window and hit Enter
   
   
2. Paste the following command in the Administrator: Windows PowerShell window and press Enter key:Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
3. Wait for PowerShell to execute and complete the command. Ignore the few errors (in red color) that may pop up.
4. When it finishes, try hitting Start and hopefully it’ll start working. If not, this solution won’t apply to you, unfortunately.

This didn't actually work I have my cmd open still and nothing has happened. Anything else that can resolve this issue? Any help is appreciated!

Powershell is not the same as Command Prompt. In the search, type "powershell" and run it as admin, then paste the command and press Enter.

Maybe it is taking a long time to load Windows Explorer, which is File Explorer, your taskbar, etc. Try defragging your HDD, and if it keeps happening press Ctrl+Shift+Esc, go to File > Run New Task, type Explorer.exe, and click OK. See if it opens then. Also, while you have task manager open, check your CPU, RAM, and Disk usage and post it here, please.
