I was looking for a way to find out how long my PC had been running a few weeks ago and had trouble finding something that satisfied my needs, I found a Visual Basic Script that worked but found it too long. But searching trough AutoIt WINAPI help found that it really was as simple as the following little script. #include <WinAPISys.au3> #include <WinAPIMisc.au3> Local $Uptime = _WinAPI_StrFromTimeInterval(_WinAPI_GetTickCount()) MsgBox(0, '', "PC Uptime ==> " & $UpTime) Hope it helps...
