Date and Time of Windows Installation

[j2k]

Hi,

How can I find out the date and time Windows was installed? I believe the entry is in the registry.

For Windows 2000 the install date is logged in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\InstallDate.

The only problem is that the date is stored as the number of seconds that have expired since January 1st 1970. On my machine the value is 970242124.

Maybe someone will be able to provide a conversion program.

The folder date/time in Windows Explorer is a pretty good clue as to when any program was installed. Also the date/time on many *.ini files, these are created upon installation.
