Exclude part of server name from Get-Snapshot PowerShell Script

Question

What I am trying to do is get a list of VM Snapshots but exclude any snapshots that contain the VM naming convention of "ABCDE" and that the snapshots are over 3 days old and output it to a text file.

The script that I have thus far is the following but it is not excluding the servers that begin with "ABCDE".

# Get VM Snapshot Information excluding anything with HEIEPC

Get-VM | Where {$_.Name -ne "ABCDE"} |
    Get-Snapshot |
    Where-Object { $_.Created -lt (Get-Date).AddDays(-3) } |
    Format-List | Out-File $Log -Append

You're checking for VMs with the exact name "ABCDE". To check for VMs whose name begins with "ABCDE" use the -like operator and a wildcard:

Get-VM | Where { $_.Name -notlike 'ABCDE*' } | ...

Make the pattern *ABCDE* if you want to exclude VMs with the substring "ABCDE" anywhere in their name (not just the beginning).
