I used to make my own ringtones and then lost interest.
In the decade when I was having to install windows, we did four things on NT4.0 Workstation (and later) and Win9x, above all else:
Double checked Regional Settings / Keyboard.
Disabled AutoRun in Registry.
Set Desktop to "No Sounds".
Disabled File & Printer sharing.
We made sure new accounts had these settings and only the designated Admin had an Admin account on NT.
