MS security bulletin Vulnerabilities in GDI+ Could Allow Remote Code Execution (957488) lists MS products affected including VFP 8.0 and VFP 9.0. It supersedes MS security bulletin MS08-052 - Vulnerabilities in GDI+ Could Allow Remote Code Execution (954593). I blogged about it at GDI+ security updates for VFP 8.0 and VFP 9.0

Powershell comes with a cmdlet called "Measure-Command" that can execute a block of commands and measure how long it takes to run. It's analogous to the unix "time" command.
