Changing the NTP update interval in Windows

Default is 604800 seconds (7 days), which is way way too long. On my machine, I'm getting clock skews of close to a minute as a result, and that's not acceptable when you're swapping files around for compilation for instance.

To set this value to a more reasonable interval, you need to update the following key:


Windows 7, I hardly knew ye...

Blah, blah, blah, Windows 7 is great, blah, blah...

Oh, you were actually expecting something in that range? Not on this blog I'm afraid.
When Windows 7 consistently freezes within 4 hours of a fresh install (happened on Vista too, so I don't think it's a Win 7 issue only. Past that initial freeze the system is stable enough though), needs a full reinstall less than one month after it, and putting the computer to sleep or rebooting is akin to Russian roulette (will it boot again, or will just remain frozen forever and require, not only a hard reset, but a complete PSU unplug? - heck, I have a hackintosh OS-X working better than that on hardware that was never meant to be supported by Apple - go figure!)

And now, once again, it's time for a clean Windows 7 reinstall, which means reinstalling all the apps, and having to do that every few months to keep the hardware in running order (because I actually DO something with my machine you know, like installing drivers by the truckload for development purposes - it's not just for internet and multimedia) is getting a bit old.

Today's tip then is then is how to avoid reinstalling the WinDDK, when you still have the files (in E:\WinDDK\7600.16385.0\ for instance) and all you are interested are the build environment shortcuts.
Windows 7 x64 free build environment shortcut:
C:\Windows\System32\cmd.exe /k E:\WinDDK\7600.16385.0\bin\setenv.bat E:\WinDDK\7600.16385.0\ fre x64 WIN7 no_oacr
Same thing for x86:
C:\Windows\System32\cmd.exe /k E:\WinDDK\7600.16385.0\bin\setenv.bat E:\WinDDK\7600.16385.0\ fre x86 WIN7 no_oacr
And for reference, setenv usage:
Usage: "setenv  [fre|chk] [64|x64] [WIN7|WLH|WXP|WNET] [bscmake] [no_oacr] [separate_object_root]"
