Grabbing Info via PowerShell

Simple Post to start collecting things I often forget but use enough that I need to know.

Hardware:

$Manufacturer = (Get-WmiObject -Class:Win32_ComputerSystem).Manufacturer
$ComputerModel = (Get-WmiObject -Class:Win32_ComputerSystem).Model
$HPProdCode = (Get-CimInstance -Namespace root/cimv2 -ClassName Win32_BaseBoard).Product

General:

#Machine Name
$MachineName = $env:ComputerName

#Current Windows 10 Release ID
$CurrentBuild = Get-ItemPropertyValue "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion" 'ReleaseId' -ErrorAction SilentlyContinue

#Last Reboot
$LastReboot = (Get-CimInstance -ClassName win32_operatingsystem).lastbootuptime

#Logged on User
$Loggedon = Get-WmiObject -ComputerName $env:COMPUTERNAME -Class Win32_Computersystem | Select-Object UserName

#Current OS Info
Function Convert-FromUnixDate ($UnixDate) {[timezone]::CurrentTimeZone.ToLocalTime(([datetime]'1/1/1970').AddSeconds($UnixDate))}
$CurrentOSInfo = Get-Item -Path 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion'
$InstallDate_CurrentOS = Convert-FromUnixDate $CurrentOSInfo.GetValue('InstallDate')
$ReleaseID_CurrentOS = $CurrentOSInfo.GetValue('ReleaseId')
$BuildUBR_CurrentOS = $($CurrentOSInfo.GetValue('CurrentBuild'))+"."+$($CurrentOSInfo.GetValue('UBR'))

Client Auth Cert

if($ClientAuthCert = Get-ChildItem Cert:\LocalMachine\My | Where-Object {$_.EnhancedKeyUsageList -match 'Client Authentication'})
    {
        
    if ($ClientAuthCert.Count -gt 1)
        {
        $ClientAuthCert = $ClientAuthCert | Sort-Object -Property NotAfter | Select-Object -Last 1
        }
    if ($($ClientAuthCert.NotAfter) -lt (get-date))
        {
        Write-Host "  Client Auth Cert Expired! $($ClientAuthCert.NotAfter)" -ForegroundColor red
        }
    else
        {
        Write-Host "  Client Auth Cert Installed, Expires: $($ClientAuthCert.NotAfter)" -ForegroundColor Green
        }
    }
Else
    {
        Write-Host "  No Client Auth Cert Installed" -ForegroundColor Yellow

Battery Info

if (Get-WmiObject -Class win32_battery)
    {
    if ((Get-WmiObject -Class Win32_Battery –ea 0).BatteryStatus -eq 2)
        {Write-Host "  Power Status: Device is on AC Power" -ForegroundColor Green}
    Else
        {
        Write-Host "  Power Status: Device is on Battery" -ForegroundColor yellow
        Write-Host "  Power Status: Time Remaining on Battery = $((Get-WmiObject -Class win32_battery).estimatedChargeRemaining)" -ForegroundColor yellow
        }
    }

Language Pack Info

$languagePacks = $OSInfo.MUILanguages
foreach ($languagePack in $languagePacks)
    {
    if ($languagePack -ne "en-US")
        {
        Write-host "  Additional Language Pack Installed: $languagePack" -ForegroundColor Yellow
        }
    }
