I had an update on my system in a partially installed state. Our vulnerability scanner determined one file, MSO.dll, was still out of date. It recommended a patch to apply. Running it gave me an error message. Here’s what to do when Windows says the update is already installed on this system and refuses to let you do anything but click OK.
Because hey, from a security analyst’s point of view, this is anything but OK. I get questions about patches in a partially deployed state all the time, so I figured I’d write about it. Here’s what I do when security updates fail to apply with this error.
If your start button disappeared, I have the fastest possible fix for you. It works with Windows 7, Windows 8, and Windows 10, and server versions, in addition to versions of Windows you shouldn’t be running anymore.
When opening locally stored PDFs in Chrome, sometimes Chrome says the file may have been moved or deleted. More specifically, the error message says “Your file was not found. It may have been moved or deleted. ERR_FILE_NOT_FOUND.” But nobody moved or deleted the file, because I just clicked on it. In fact, I could still see it sitting right there in Windows Explorer.
Oddly enough, I had other files in the very same folder that opened fine. No errors. Here’s how I found the problem, fixed it, and avoided it in the future.
From time to time, Windows patches will fail to install because a server doesn’t have enough space to install them. Finding the ginormous files are that are hogging all the space on the C drive is really tedious if you do it by clicking around in Windows Explorer, but there’s a better way.

The micro SD card in my Android phone (a Samsung Galaxy S 4G, if that helps) quit working suddenly, and I finally got around to investigating it on Friday. I ended up having to solve two problems to do it, though.
Let’s start with Windows 7’s Disk Manager hanging at the message that says “Connecting to Virtual Disk Service.”
You can improve the speed of printing slightly and, depending on the nature of your print jobs, dramatically reduce disk writes if you move the print spool directory to your ramdisk. It’s a little performance tweak you might have never heard of, but it’s helpful.
This trick works best with a ramdisk product that loads a disk image at startup, such as Dataram Ramdisk.
I was looking deeper into Firefox optimization, and I found Adventures in Firefox-places.sqlite. It’s a pretty intense analysis that goes beyond the usual simple, in-browser SQL vacuum that I’ve mentioned in the past. It was written with Mac OS X and Linux in mind, which is fine, but if you run Windows, you might want to do the same thing.
It has two benefits. It speeds up Firefox, and it reduces the amount of disk space your Firefox profile occupies. The two things are related; smaller databases are quicker and easier to navigate than large ones. As for why you should care about the amount of disk space it takes up, well, on an SSD every megabyte counts.
Windows 7 can suffer from old-age disease, where it thrashes hard drives, programs quit responding, and it generally becomes unusable. I’m beginning to wonder if my main PC might be suffering from this. Microsoft prescribes this cure.
If you’re comfortable with a command line, I can make the solution faster and easier. Read more
