By default, the Background Intelligent Transfer Service (BITS) which is used by Automatic Updates will use idle network bandwidth for downloading updates. This is normally not a problem. One case where it can be a problem is you have a large LAN that shares a single DSL connection. BITS doesn't see that that DSL connection is shared. Consequently,...

In a previous life, I wrote database software. A customer complained that one of their reports was taking an unacceptably long amount of time to generate, and I was asked to take a look at it even though it wasn't my account. The report was a vacation-days report, listing the number of vacation days taken and available for each employee. Vacati...

If you have a file or directory that does not have a last-modified date, you may find that it causes Explorer to sort very strangely. (How do you get a file or directory with no last-modifiied date? It's hard to do; you need the help of an external file system.) Why is this? As we learned earlier, a sort comparison function must impose a total or...

Note that this applies only to kernel HANDLEs; it does not apply to pseudo-handles or to any other type of handle (USER handles, GDI handles, multimedia handles...) Kernel handles are things you can pas...

Sometimes people try too hard. You can download a C# program to look for a file on your PATH, or you can use a 90-character batch file:

The function creates a new process, but it doesn't wait for the process to get off the ground before returning. It just creates the process object and lets it go to do its thing. The Win32 process model is that each process initializes itself in context. When a process object is created, it is practically empty, save for enough information to g...
