How to use Windows PowerShell

About how to use execution permissions

To prevent the execution of malicious scripts, PowerShell has an execution policy. By default, this execution policy is set to Restricted, which means that PowerShell scripts cannot be executed. You can use the following cmdlet command to determine the current execution policy: Get-ExecutionPolicy The execution strategies you can choose to use are:

Restricted - The script cannot be run;

RemoteSigned - locally created scripts can run, but scripts downloaded from the Internet cannot (unless they have a digital signature signed by a trusted publisher);

         AllSigned – The script can only be run if it is signed by a trusted publisher;

​​​Unrestricted – Script execution is unrestricted, regardless of where they come from and whether they are signed or not.

You can use the following cmdlet command to set the PowerShell execution policy: Set-ExecutionPolicy

How to create an event log

Administrators can use PowerShell to create a new event log and view the status of the event log. They can also use PowerShell to easily add a new event log. For example, you can use the following code to create a new application named TestSource. Event log.

New-EventLog -LogName Application -Source TestSource

If you want to write information to the Windows event log, you only need to call the WriteEntry method of EventLog. The specific code is as follows:

       Write-EventLog -LogName Application -EventId 1234 -Source TestSource -Message "Test write"

​ ​ Additionally, you can quickly view the configuration status and number of events of critical Windows event logs by using Windows PowerShell.
