How to find Inactive computer accounts in active directory?

Do you know how can we do this? Either we query the AD to get the information by writing code in C# or manually check the AD for the inactive accounts. But, there is another simple way which will get this information without any big efforts. Yes, using Powershell script.

$COMPAREDATE=GET-DATE
$NumberDays=90 
$CSVFileLocation='C:\TEMP\OldComps.CSV' 
GET-QADCOMPUTER -SizeLimit 0 -IncludedProperties LastLogonTimeStamp | where { ($CompareDate-$_.LastLogonTimeStamp).Days -gt $NumberDays } | Select-Object Name, LastLogonTimeStamp, OSName, ParentContainerDN | Sort-Object ModificationDate, Name | Export-CSV $CSVFileLocation 

You have to provide the days - the timeline of inactive accounts and where to save the output of inactive accounts list.
