Powershell.exe

Question

Powershell.exe

Sharon J 0

After I uninstalled Office 365 (preloaded on PC), I am getting the error below, cannot open some programs, and can't launch the Microsoft help. Can someone please help fix this? Should I just reinstall MS Office? Will that fix the powershell.exe launch issue?

Hello there! I'm glad to help you today!

Thank you for the information. May I ask if you are on a work computer? Reinstalling office might not fix this. The error code mostly means corrupted system files.

Let's first check for corrupted system files.

Click Start, then type cmd.

Right-click on "Command Prompt" and select "Run as administrator".

In the Command Prompt window, type:

sfc /scannow

Press Enter.

Wait for the scan to complete. It may take several minutes.

Follow any instructions shown after the scan finishes.

Next, open Command Prompt as an administrator again. In the Command Prompt window, type

DISM /Online /Cleanup-Image /RestoreHealth

and press Enter.

Then, please test again.

the sfc /scannow has been stuck at 16% complete for 30 minutes. Should I close out the screen and start over?

So, I hit the "enter" key and it finished the test with "no integrity violations." the 2nd command found no problems also. After a reboot, I received a message to update to new version of powershell. Sending me to aka.ms/pswindows. How do I know which one to install?

I found out how to do that but when I try to install it under the administrator, it said I do not have the proper permissions. How do I fit that now?

OK. I was able to update the powershell version, rebooted, and STILL get the same error message and have the same issues with accessing some programs.

Any other suggestions?

Thanks. I can open Powershell.

I uninstalled my antivirus software and can get into my applications. However, now I get a message to update the powershell version.

I ran the $PSVersionTable and I have V5.1. Do I need to update? If I do not, how do I get rid of this message?

Thank you for the confirmation. it just means PowerShell is running, and it starts you in your user folder (C:\Users\sjvfl). That’s the default startup location.

Please press Win + R - type:

powershell

and press Enter.

If it opens, you’re fine, and you just need to fix the shortcuts.

I would suggest to make a new shortcut if this is the case.

Thank you for getting back to me. May I ask if you are on a work computer?

I need to know because there might be policies that intentionally block PowerShell.

Please also check if there are any third party services that's doing this.

Press Windows + R, type msconfig, and press Enter.

In the System Configuration window, go to the Services tab.

Check Hide all Microsoft services, then click Disable all.

Go to the Startup tab and click Open Task Manager.

In Task Manager, disable all startup items.

Close Task Manager, then click OK in System Configuration.

Restart your computer.

First, I want to thank you for helping me. This is a home computer, not for business. I was able to download a newer version of powershell, but I am still getting the same message. I am thinking the startup path is looking in the wrong place. Do you know how to change that?

When I click on the new Powershell 7, I get the following:

PowerShell 7.5.3

PS C:\Users\sjvfl>
