Powershell function for showing some system information

This is a function I created just because I wanted to toy around with Powershell and get-wmiobject. Also, this is my first function where I made it possible to use a switch parameter.

What the function does is gather some system information using get-wmiobject. The info is written to a temp file and then shown using out-gridview.
If the KeepTempFile parameter is used the temp file is saved in the users profile, if not it is deleted after the function finishes.

Heres the code:

function Show-Debug
 {
 Param(
 [switch]$KeepTempFile
 )
 $tempfile = "$env:userprofilepstempfile.txt"
 New-Item $tempfile -ItemType file -Force
 Get-WmiObject -Class Win32_ComputerSystem |fl Manufacturer,Model,Name,Domain,PrimaryOwnerName | Out-File $tempfile -Append
 Get-WmiObject -class "Win32_BIOS" -namespace "rootCIMV2" -computername localhost | fl BIOSVersion,Serialnumber,Status | Out-File $tempfile -Append
 Get-WmiObject Win32_OperatingSystem | fl @{Expression={$_.Caption};Label="OS Name"},SerialNumber,OSArchitecture,Version | Out-File $tempfile -Append
 Get-WmiObject Win32_PhysicalMemory | ft Tag,Capacity,Speed | Out-File $tempfile -Append
 Get-WmiObject Win32_Processor | fl DeviceID,Manufacturer,Caption,Name,NumberOfCores,NumberOfLogicalProcessors,MaxClockSpeed,CurrentClockSpeed,L2CacheSize,L3CacheSize,Status | Out-File $tempfile -Append
 Get-Content $tempfile | Out-GridView
 if ($KeepTempFile){
 Write-Host "Log file is now saved as $tempfile"
 }
 Else {
 Remove-Item $tempfile
 }
