“We removed extra line breaks from this message.” Well, how helpful of you. Now the email from my crontab script is all in one line. You can disable this “helpful functionality” permanently in Outlook by doing this: Open Outlook On the File tab, select Options In the Options window, select Mail In the Message format […]
So, the machine auto-activates Windows 10 Home Edition at install time. No prompts, no nothing. You insert the generic upgrade key, and it throws an unhelpful error message back at you: This probably surprises nobody, but trying again, as the above message suggests, will not work for you. The solution? Stuff the install media (in […]
Cheap Windows 10 capable devices often come with very limited internal storage space. To make use of this, it is of course crucial that Windows itself takes up as little space as possible. To combat the bloat, there’s a little known feature in compact.exe, the built-in disk compression tool, that compresses the operating system itself, […]
I recently reinstalled one of these cheap-ass, but surprisingly well built for the price, “ultraportable” laptops. Here’s the WiFi driver to get you started, and the remaining drivers that were not available from Windows Update. Enjoy.
Working with multiple screens, I often use several windows in Visual Studio. For a while now, I’ve been annoyed by all the miscellaneous windows forcing themselves on top so I couldn’t open a browser on one screen and switch to the code on another screen without the window on the browser’s screen popping up to […]
Some hypervisors for virtual machines do not properly support sending a fake system time to the guest operating system, thus making Windows guests display the wrong time if their timezone is set to anything except UTC. This happens because Windows, by default, keeps the system clock set to the local time. This is stupid. The […]

Just a short note to self here, as the process is fully documented at Microsoft’s website (local archive here). The command to use is: C:\windows\system32> redircmp ou=mycomputers,DC=contoso,dc=com Of course you have to customize the location to fit your domain.
I was recently debugging a case where a customer’s installation was hanging due to a database lock. The issue turned out to be that the database was not set to a default transaction level of READ COMMITTED SNAPSHOT, which the product expects. Regardless, while troubleshooting the issue, I stumbled upon a very useful SQL query […]
