PS | Deleting Local User Profile | Get-WmiObject -Query Not working - powershell

Question

I am literally 1 Line away from getting this PS Task completed. Would one of you mind taking a look? This script simply checks the users directory, checks each local users creation date, and deletes it using WMIObject. Everything works up to line 34 (Marked it with ===> in Code block). Error being thrown on my WMI Query. I cannot find out why... Working with WMIExplorer it looks correct.
$Admin = "Administrator"
foreach($file in Get-ChildItem C:\Users\)
{
if ($file -in $Admin)
{
Write-Host = "`r`nUser account is" $file ". This is an Administrator Account, it will not be deleted."
}
else
{
Write-Host = "`r`nUser account is" $file ". Checking profiles age..."
$FileDate = (Get-item C:\Users\$file).CreationTime
Write-Host = $FileDate
$TestDate = (Get-Date).addDays(-30)
Write-Host = $TestDate
If ($FileDate -lt $TestDate)
{
Write-Host = "Since" $file "is older than 30 Days (" $FileDate ") it will be deleted."
$UserAccountPath = "C:\Users\$file"
====> $WMIQuery = "SELECT * FROM Win32_UserProfile WHERE localpath = $UserAccountPath"
$UserProfile = Get-WmiObject -Query $WMIQuery -ComputerName $Computer
Remove-WmiObject -InputObject $UserProfile
}
else
{
Write-Host = "Since File is dated less than 30 days old (" $FileDate ") it will not need to be deleted."
}
}
}
When it is run I get the following Error:
Get-WmiObject : Invalid query "SELECT * FROM Win32_UserProfile WHERE localpath = C:\Users\radconrm"

I look forward to your insight! Thank you for your time in advanced!

Double the backslashes. Add quotes to what localpath is equal to. It's like SQL.
$UserAccountPath = "C:\\Users\\$file"
$WMIQuery = "SELECT * FROM Win32_UserProfile WHERE localpath = '$UserAccountPath'"
$UserProfile = Get-WmiObject -Query $WMIQuery -ComputerName $Computer
You may find something like this easier:
get-wmiobject win32_userprofile | where localpath -eq c:\users\$file
