powershell - Get idle time of machine -


is there way idle time of machine, in amount of time machine has not been used for, in minutes/hours using powershell or batch file?

here's powershell solution uses win32 api getlastinputinfo.

add-type @' using system; using system.diagnostics; using system.runtime.interopservices;  namespace pinvoke.win32 {      public static class userinput {          [dllimport("user32.dll", setlasterror=false)]         private static extern bool getlastinputinfo(ref lastinputinfo plii);          [structlayout(layoutkind.sequential)]         private struct lastinputinfo {             public uint cbsize;             public int dwtime;         }          public static datetime lastinput {             {                 datetime boottime = datetime.utcnow.addmilliseconds(-environment.tickcount);                 datetime lastinput = boottime.addmilliseconds(lastinputticks);                 return lastinput;             }         }          public static timespan idletime {             {                 return datetime.utcnow.subtract(lastinput);             }         }          public static int lastinputticks {             {                 lastinputinfo lii = new lastinputinfo();                 lii.cbsize = (uint)marshal.sizeof(typeof(lastinputinfo));                 getlastinputinfo(ref lii);                 return lii.dwtime;             }         }     } } '@

and example usage:

for ( $i = 0; $i -lt 10; $i++ ) {     write-host ("last input " + [pinvoke.win32.userinput]::lastinput)     write-host ("idle " + [pinvoke.win32.userinput]::idletime)     start-sleep -seconds (get-random -minimum 1 -maximum 5) }
