function Install-PowerShellISE { <# .SYNOPSIS Install the Windows PowerShell ISE if you removed it after installing VS Code. .DESCRIPTION This script installs the Windows PowerShell ISE if it is not already. It includes a step that resets the Windows Automatic Update server source in the registry temporary, which may resolve errors that some people experience while trying to add Windows Capabilities. This was created because Out-GridView in Windows PowerShell 5.1 does not work without the ISE installed. However, Out-GridView was rewritten and included in PowerShell 7 for Windows. .EXAMPLE Install-PowerShellISE .NOTES To Do: - Check for Windows client vs Windows Server OS - Add parameter to make the Windows Update registry change optional - Requires admin but adding that breaks the build #> [CmdletBinding()] param () if ((Get-WindowsCapability -Name 'Microsoft.Windows.PowerShell.ISE~~~~0.0.1.0' -Online).State -eq 'Installed') { Write-Output 'The Windows PowerShell ISE is already installed.' } else { # Resetting the Windows Update source sometimes resolves errors when trying to add Windows capabilities $CurrentWUServer = Get-ItemProperty -Path 'HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU' -Name 'UseWUServer' | Select-Object -ExpandProperty UseWUServer Set-ItemProperty -Path 'HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU' -Name 'UseWUServer' -Value 0 Restart-Service wuauserv try { Get-WindowsCapability -Name Microsoft.Windows.PowerShell.ISE~~~~0.0.1.0 -Online | Add-WindowsCapability -Online -Verbose } catch { Write-Error "There was a problem adding the Windows PowerShell ISE: $error" } Set-ItemProperty -Path 'HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU' -Name 'UseWUServer' -Value $CurrentWUServer Restart-Service wuauserv } } |
