Right-click the file that you saved, and select Run with PowerShell.
If you're asked the following question, select Yes.
Do you want to allow this app to make changes to your device?
The PowerShell script resets the Windows Search feature. When the word Done appears, close the PowerShell window.
If you receive the following error message:
Cannot be loaded because running scripts is disabled on this system
enter the following command on the command line of the PowerShell window, and then press Enter:
The current policy appears in the window. For example, you might see Restricted. We recommend that you note this value because you'll have to use it later.
Enter the following command on the command line of the PowerShell window, and then press Enter:
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted
You'll receive a warning message that explains the security risks of an execution policy change. Press Y, and then press Enter to accept the change.
To learn more about PowerShell execution policies, see About Execution Policies.
After the policy change is completed, close the window, and then repeat steps 2-4. However, when the Done message appears this time, DON'T close the PowerShell window. Instead, press any key to continue.
Revert to your previous PowerShell execution policy setting. Enter the following command on the command line of the PowerShell window, press the Spacebar, enter the policy value that you noted in step 5, and then press Enter:
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy
For example, if the policy that you noted in step 5 was Restricted, the command would resemble the following one:
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Restricted
You'll receive a warning message that explains the security risks of an execution policy change. Press Y, and then press Enter to accept the change and revert to your previous policy setting.
Close the PowerShell window.
If your organization has disabled the ability to run scripts, contact your administrator for help.
