Here are some steps you can follow to troubleshoot and fix common Windows installation problems using PowerShell:

• Check for updates:

Import-Module Microsoft.PowerShell.Security


Get-WindowsUpdate | Select-Object -ExpandProperty Status

This command checks if the Windows Update service is up-to-date.

• Run the System File Checker (SFC) tool:

Set-ExecutionPolicy -Scope CurrentUser -Force

Invoke-Command -ComputerName localhost -ScriptBlock {

    & C:\Windows\System32\WindowsInstallatory.exe /checkfile

}

This command runs the SFC tool to scan and repair any corrupted system files.

• Check for disk errors:

Get-WmiObject Win32_DiskDrive | Where-Object {$_.FreeSpace -gt 0}

Invoke-Command -ComputerName localhost -ScriptBlock {

    & C:\Windows\System32\wmic logicaldisk get diskstatus

}


if ($Error[0].Exception -ne "Exception") {

    Set-ExecutionPolicy -Scope CurrentUser -Force

}

This command checks if any disk is free space ( greater than 0 ). If it finds one, you can ignore the error.

• Run a System File Checker for files in C:\Windows:

Set-ExecutionPolicy -Scope CurrentUser -Force

Invoke-Command -ComputerName localhost -ScriptBlock {

    & "C:\Windows\System32\wmic logicaldisk get diskstatus" /value -property path, freeSpace

}

This command runs a System File Checker for files in the C:\Windows directory.

• Check the Windows installation logs:

Get-WmiObject Win32_OperatingSystem | Where-Object {$_.LastWriteTime -lt Get-Date(2016, 1, 1)}

This command checks if there are any corrupted or incomplete installation files.

• Check the Event Viewer logs:

Get-WmiObject Win32_Event | Where-Object {$_.Category -eq "Installation" | Where-Object {$_.EventID -gt 0}}

This command checks for errors or warnings in the Event Viewer logs.

• Run a system restore to a previous installation:

Restorerestore /Path:C:\Windows\WinSxBl

This command runs a system restore to a previous Windows installation (in this case, Windows 10).

• Check for disk space issues with the Windows Installation Media:

Get-WmiObject Win32_DiskDrive | Where-Object {$_.FreeSpace -gt 0}

Invoke-Command -ComputerName localhost -ScriptBlock {

    & C:\Windows\System32\wmic logicaldisk get diskstatus

}


if ($Error[0].Exception -ne "Exception") {

    Set-ExecutionPolicy -Scope CurrentUser -Force

}

This command checks if any disk space is available in the Windows Installation Media.

• Run a System File Checker for files on the Windows Installation Media:

Set-ExecutionPolicy -Scope CurrentUser -Force

Invoke-Command -ComputerName localhost -ScriptBlock {

    & "C:\Windows\System32\wmic logicaldisk get diskstatus" /value -property path, freeSpace

}

This command runs a System File Checker for files in the Windows Installation Media.

• Check for any pending installation or repair operations:

Get-ChildItem -Path C:\Windows\ ( Get-Date -Year 2018 + $((Get-Win32Process).CreationTime / 1000) ) > * -Directory

This command checks if there are any pending installation or repair operations.

After trying these steps, you may need to use more advanced PowerShell commands, such as Get-WmiObject and Invoke-Command, depending on the specific problem you’re experiencing.
