- Restricted (the default)
- AllSigned
- RemoteSigned
- Unrestricted
Restricted: No scripts or profile files are run, which is the default execution policy. Windows PowerShell can be run interactively from the command line.
AllSigned: Runs only scripts that are signed by a publisher that you trust. Protection depends on how trustworthy those you choose to trust are.
RemoteSigned: Runs all scripts except those that originate from applications like Microsoft Outlook, Internet Explorer, Outlook Express, and Windows Messenger. The latter’s script and configuration files must be signed by someone you trust.
Unrestricted: Runs all scripts.You receive a warning when attempting to run a script downloaded from applications like Microsoft Outlook, Internet Explorer, Outlook Express, and Windows Messenger.
If the execution policy is restricted, you will see a display like that in Figure down below. The value of the ExecutionPolicy property is Restricted as shown below
Normally, you would use the cmdlet to set the execution policy. It’s also possible to make the necessary change directly in the registry but the set-executionpolicy is much more convenient to use.
Using the cmdlet requires Administrator privileges. Firstly run powershell as Administrator as shown below
To change the execution policy to Unrestricted, use this command:
To change the execution policy to Remote Signed, use this command:
To change the execution policy to All Signed, use this command:
If you later want to reset the execution policy to Restricted, simply supply that as the value of the -executionPolicy parameter.
Important Note: Powershell script doesn’t run by double clicking powershell script with .ps1 extension as which is the case with VBScript, all powershell script need to be run with in powershell or through run command. You need to provide location of your script repository while running your powershell script within powershell.
For example: As with Computer Anthem we have all of our Powershell Scripts saved in C: drive within folder “scripts”, as shown below, C:\scripts
Now to run any script that are saved in C:\scripts, firstly we need to change the path within Powershell which can be done as follows with command cd c:\Scripts
Once you type above path and hit enter, you will be on path C:\Scripts
Now you can run any powershell script saved under that folder, we have script called test2.ps1 Saved in “c;\scripts” folder, to run test2.ps1, we just need to type .\test2.ps1 as shown below
There is another way to run Powershell script without changing the path with command & “C:\Scripts\test2.ps1” as shown below.
You can also run Powershell script through run command powershell.exe -noexit c:\scripts\test2.ps1

for %a in (*.cmd) do %a
I found invoke-command, foreach-item and other stuff, but can't get it run.
This is just to show, that I've tried it, these line does *NOT* work!
invoke-command -scriptblock {Get-ChildItem -filter *.ps1}
or
Get-ChildItem -filter *.ps1 | % {invoke-command $_.name}
This *MUST* be possible with a simple one-liner, isn't it?
