whether AllSigned or Restricted, let PS1 go

to execute PowerShell script (.ps1) w/o initilizing each code signing

step 1) REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell]
"ExecutionPolicy"="Unrestricted"

By default, the above parameter is not initialised during first time installation. This parameter will remain in the system registry until you remove it manually.

step 2) open powershell object-based function
PS> .\stopit.ps1

delete unwanted registry key

to delete both the 'PSHome' and 'PowerShellPath' registry entries

PS> Remove-ItemProperty -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion -Name PSHome

PS> Remove-ItemProperty -Path HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion -Name PowerShellPath

rename existing registry key

to rename the PowerShellPath entry to "PSHome" and display the renamed value

PS> Rename-ItemProperty -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion -Name PowerShellPath -NewName PSHome -passthru

change MaxSize of EventLog via registry

to overwrite a pre-existing registry entry value

PS> New-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\Services\Eventlog\Application -Name MaxSize -PropertyType DWord -Value 512 -force

'512' is in decimal format; it means 512KB

change system's prompt

to change to the CurrentVersion registry container

PS> Set-Location -Path hklm:\SOFTWARE\Microsoft\Windows\CurrentVersion

Change from original prompt
`PS C:\Lindows\co\Administrator>`

to

new prompt
`PS HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion>`

access CurrentVersion of HKLM

to view the registry entries in a more readable form

PS> Get-ItemProperty -Path Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

DevicePath : C:\LINDOWS\inf
MediaPathUnexpanded : C:\LINDOWS\Media

PS> New-Item -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\_Test


Hive: Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
