Howdy, @Brink! If you use Get-CimInstance instead of Get-WmiObject, the conversion is automatic.

Powershell:
ps> (Get-WmiObject Win32_OperatingSystem).InstallDate
20250702105206.000000-240

ps> (Get-CimInstance Win32_OperatingSystem).InstallDate

When one looks up the install date through System > About, Is that the actual install date or the date of the last major update? The reason I'm asking is because It's showing I clean installed Windows 25H2 on 9/20/2025. I would have sworn that I've been running 25H2 longer than that.

Hello mate, :alien:

It will be the date of the latest "feature" update installed.
