# Start PS-Code
$DeleteIfLastUseTimetIsOlderThen = (get-date).AddDays(-5).tostring("yyyy-MM-dd hh:mm:ss”)
$GetLocalAccounts = Get-WmiObject -ComputerName localhost -Filter "Special=False" -Class Win32_UserProfile |
Select-Object Sid, LocalPath, #{Label='LastUseTime';Expression={$_.ConvertToDateTime($_.LastUseTime)} }
foreach ($UserAccount in $GetLocalAccounts)
{
if ($GetLocalAccounts.LastUseTime -Ge $DeleteIfLastUseTimetIsOlderThen )
{ Write-host "Account is old, Remove me"}
Else
{ Write-host "Account is not old"}
}
# End PS-Code
The thing is that it doesn't matter if I change the value "$DeleteIfLastUseTimetIsOlderThen " to 1,2,3,4 or 55, everything seems to be old.

The issue here is twofold. One is that you want to use a less than comparison when looking for an older date since a date in the past is less than a date in the future. Second, you want to compare each date in your collection ($GetLocalAccounts) with a specific fixed date ($DeleteIfLastUseTimeIsOlderThan). To do this with your code structure, you will need to check against the current object ($UserAccount) in your for loop.
# Start PS-Code
$DeleteIfLastUseTimetIsOlderThan = (get-date).AddDays(-5).tostring("yyyy-MM-dd hh:mm:ss”)
$GetLocalAccounts = Get-WmiObject -ComputerName localhost -Filter "Special=False" -Class Win32_UserProfile |
Select-Object Sid, LocalPath, #{Label='LastUseTime';Expression={$_.ConvertToDateTime($_.LastUseTime)} }
foreach ($UserAccount in $GetLocalAccounts)
{
if ($UserAccount.LastUseTime -le $DeleteIfLastUseTimetIsOlderThan )
{ Write-host "Account is old, Remove me"}
Else
{ Write-host "Account is not old"}
}
# End PS-Code
