AppData location for scripts running under SYSTEM account

Found this answer to my question today:

AppData location when running under System user account

As it took far too much Googling to find this, if you need to access the AppData folder for the System account, go here:

C:\Windows\System32\config\systemprofile\AppData\Local
C:\Windows\SysWOW64\config\systemprofile\AppData\Local
I hit this because we needed to clear the NuGet package cache for a TeamCity build agent which was running as a service under the System account.
