Where does "psinfo.exe" fetch it's "Install date" data?
Where does "psinfo.exe" fetch it's "Install date" data?
At first, I was curious on where "systeminfo.exe" (Windows integrated util) fetches its Original Install Date data. Finally, after research, I figured out that its from a registry key. This explained why my systeminfo was giving wrong install date (I had somehow managed to mess up this reg value). I then tried util "PsTools" (http://technet.microsoft.com/en-us/sysinternals/bb896649.aspx) and it's 'psinfo.exe'. It returns the correct install date, EVEN though the regkey is corrupt/incorrect. This dazes n' confuzes me. It has to mean that Mark's utility fetches the data from someplace else. I'm just curious on where! It would be cool to know. It indeed seems to be the same "original" data, 'cuz I tried it on computer without corrupt registry, and systeminfo.exe showed exactly the same data as psinfo.exe, except for that psinfo.exe tends to ignore possible daylight saving at time of install. I tried to search my registry for the psinfo.exe-given installation date (given as ctime hex/dec), but wo/ any further hits.
So, where should I put this question? ;)
