To execute a command in each subdirectory of a directory tree from a batch file, you can adapt the following: (If you want to play with this command from the command prompt, then undouble the percent signs.) The option enables various special behaviors of the command. The most important change is that a string in single-quotation marks caus...

On Windows Vista with User Account Control enabled, when you right-click a program and select Run as Administrator, the elevation prompt contains a particular snippet of warning text and a corresponding color-coding. Here are what the four colors mean. You can learn about the philosophy behind UAC in this Channel9 interview. Pre-emptive snarky...

Long Zheng does it again. He follows up his interview with Hamad Darwish with a report on what Hamad has been doing lately, as well as links to high resolution versions of the entire Vista wallpaper photo shoot, including photos that didn't make the final cut.

I promised to talk more about NMI, so here it is. What generates an NMI? What does it mean? The first question is easy to answer but doesn't actually shed much light: Any device can pull the NMI line, and that will generate a non-maskable interrupt. Back in the Windows 95 days, a few really cool people had taken the ball-point pen trick one...

One of my colleagues recently posted the story of the work he did to get laptops to resume quickly. The fun part was implementing the optimizations in the kernel. The not-fun part was finding all the drivers who did bad things and harassing their owners into fixing the bugs. One some laptops, he could get the resume time down to an impressive on...

And since spaces are command line delimiters, you need to quote the sequence so it gets treated as a single parameter rather than two "*" parameters: Stick in a ...

A placebo setting that has been getting a lot of play in recent years is that of QoS bandwidth reservation. The setting in question sets a maximum amount of bandwidth that can be reserved for QoS. I guess one thing people forgot to notice is the word "maximum". It doesn't set the amount of reserved bandwidth, just the maximum. Changing the value...

To connect to the Microsoft corporate network from home, employees need to use smartcard authentication. But, somewhat paradoxically, you do better if you remove the smart card. A colleague of mine tipped me off to this. To initiate the connection, you have to insert the smart card and provide the smart card password. Then the system connects to ...

You can sometimes narrow down the source of a problem just by looking at the screen and moving the mouse. When you move the mouse, the cursor on the screen moves to match. This work is done in the window manager in kernel mode. The mouse hardware notifies the window manager, "Hey, I moved left twenty units." The window manager takes this value, ac...
