A customer reported an incompatibility in Windows 7: If A: is a floppy drive and they call and there is no disk in the drive, the call fails with the error . Previous versions of Windows failed with the error . Both error codes are reasonable responses to the situation. "The module couldn't be found because the drive is not ready." Programs...

It's often the case that when a question from a customer gets filtered through a customer liaison, some context gets lost. (I'm giving the customer the benefit of the doubt here and assuming that it's the customer liaison that removed the context rather than the customer who never provided it.) Consider the following request: We would like to kn...

A customer liaison reported that their customer wants to be able to access their machine without needing a password. They just want to be able to and be able to access the files right away. I guess because passwords are confusing, easy to forget, and just get in the way. Anyway, the customer discovered that they could do so on Windows XP by g...

While wasting time doing valuable background research on my computer, I received the following suggestion: For enchanced video quality, click here. It's good to know that the typo that I first encountered in 1993 is still alive and kicking. (And even though it's not important to the story, people will demand some sort of follow-up, so here it ...

Well, you can see the reason right there on the screen: You're launching it the long way around. If you launch Task Manager from the taskbar, Explorer just launches via the usual mechanism, ...

Multiple clients which connect to the same database file use the same shared memory block. Naturally, if two processes each access the same database file, each process will map the shared memor...

You may have noticed a minor inconsistency between pinning a program to the Start menu and pinning a destination to a program's Jump List. Although pinned items appear at the top of the respective lists, and both the Start menu and Jump List let you right-click an item and select Pin/Unpin, the Jump List also lets you pin and unpin an item by click...

A while back, I linked to a talk by Silviu Calinoiu on the fault-tolerant heap. But what if you don't want the fault-tolerant heap? For example, during program development, you probably want to disable the fault-tolerant heap for your program: If the program is crashing, then it should crash so you can debug it! Method 1 is to disable the ...

As I noted when I told the story of the computer programmer who dabbled in making change that my colleague had a lot of money-related quirks. For some reason my colleague felt the $2 bill deserved more attention. Every so often, he would go to the bank and buy $100 in $2 bills, then reintroduce the bills into circulation and enjoy people's reacti...
