Certain application updates generate big news, but for the most part, application updates – especially those that don’t involve a version number change – don’t generate a whole lot of press. That is, unless something goes horribly wrong with the new version. Windows drivers tend to fall into that category but that doesn’t mean they don’t have an impact on application performance.

OS Faux Pas Are Legendary

Most of the time, we hear about OS failures, spectacular or otherwise. A new version of the OS comes out and all heck can break loose. Applications, on the other hand rarely gain much attention, possibly because even the most popular applications aren’t as embedded in the marketplace as operating systems are.

When you download and install a new application or an application update, and you’re not entirely happy with the performance, before you blame the new software code or roll it back to an older version, be sure to check out your drivers and make sure that you’re running the latest versions.

That could include the latest versions of your sound and graphics drivers, which can be critical for a satisfying gaming experience. If you use your computer to do heavy-duty computing – like number-crunching or graphic design/engineering work, you’ll also want to be sure that your graphics drivers are in good working order.

For games or other applications that run simultaneously from the hard disk and a CD-ROM or DVD, you’ll also want to check the drivers for your media drive(s). If your old drivers can’t keep up, they can seriously impede the flow of data between the drive and the processor.

Don’t rely on Microsoft to dole out the driver updates you need. Not all manufacturers use the Microsoft distribution option, so you could find yourself operating under the mistaken assumption that your drivers are up-to-date when in fact, they’re not.

For me, I can think of few less appealing ways to spend my time than downloading driver updates. As a technician, I’m paid to maintain computers all the time, but when I’m on my own time, I try to maximize my return and minimize my efforts, all while keeping my PC completely updated.

That’s why I use Driver Detective to maintain my PC hardware drivers. Driver Detective downloads, installs and backs up copies of my current driver, ensuring that my drivers are always updated. I can also roll back a new driver to an older version if I’m not happy with the performance of the new installation.

Driver Detective has been downloaded and used by millions of users who swear by it. Download a copy today and see for yourself what a difference regular driver maintenance can make.

I think the software manufacturers try hard to avoid creating additional problems when they release a Windows driver update, but unfortunately, sometimes that’s exactly what happens. Driver updates should be pleasant and painless, but for some reason, they’re not.

Updating Drivers Is A Necessary Step

Updating drivers isn’t always an automatic process. In fact, there are several holes in what appears to be an “automated” update regimen that may leave users without the most current version of a driver, or with a driver version that doesn’t work the way it should.

First, most drivers you use on your Windows computer come from someplace other than Microsoft. Some – but not all – manufacturers use the Windows update to distribute driver updates. There are – to say the least – several noticeable absences. (Think Dell.) If your driver updates aren’t delivered to your computer, and you have no reliable mechanism to find out about driver updates, you could find yourself several revisions behind.

This usually crops up after a Windows update has been applied and some of your drivers no longer work, or do things you’re not expecting. If you find yourself in this situation, the best thing to do is verify – by going back to the manufacturer’s support site, if necessary – that you have the most current version of the hardware driver that supports your errant device.

Of course, going straight to the source will help ensure that you get the driver you’re looking for, but many users don’t know exactly what system they have or what driver they need. Download and install the right driver and everything is fine. Download and install the wrong driver, and well – let’s just say that things could get interesting.

If you’ve picked up a driver update from Windows Update and your hardware devices stop working as advertised, Windows may have delivered the wrong update to your computer. As I said, I think the manufacturers (and Microsoft) try hard to make sure this doesn’t happen, but occasionally it does happen. Again, the solution is to go back to the driver source and select, download and install the correct driver.

I’ve said it before. I’m not really a fan of doing dull maintenance work on my computer, and downloading drivers falls into the “dull maintenance work” category. I use a driver maintenance program called Driver Detective to manage all of the Windows drivers on my computer.

Driver Detective takes the guesswork out of driver maintenance and also helps to ensure that I get the most recent driver updates as soon as they become available. Check out Driver Detective for your driver maintenance needs.

I’m a big proponent of doing regular Windows driver maintenance. I’ve never been shy about saying that you need to keep your drivers updated. Updating your drivers, however, isn’t the only thing you need to know how to do when it comes to Windows driver maintenance. You also need to know how to install and uninstall new drivers.

Automatic Installation Doesn’t Always Provide Good Results

If you maintain your drivers on your own – that is, you personally download the drivers and go through the installation routine – you may find yourself in a tight spot on occasion. There are times when it is either desirable or necessary to roll back a driver installation – that is, go back to the older version you had been using. If you don’t know how to roll back your driver upgrade/update, you can spend a lot of fruitless and frustrating hours dealing with your non-functional or semi-functional computer, bricked hardware or unexpected system crashes.

Why? Sometimes a new driver update doesn’t work as advertised, or it “breaks” something else you need or want on your computer. In either of these cases, getting your computer back to the condition it was in before the update is the only way to reclaim your lost functions or rid yourself of troublesome software.

If you believe Microsoft, most system crashes are the result of bad third-party drivers. Whether that’s true or not makes little difference when your system has crashed for the umpteenth time and you’re simply trying to get your system back together. If you find yourself in the position of having installed a new driver, and then you experience system crashes, instabilities, or your attached hardware no longer works properly, you may want to roll back the suspect driver to an earlier version. To do this, you’ll need the Device Manager.

Access the Device Manager through the Run box under the Start menu by entering “Device Manager” and press Enter. The Device Manager manages all devices connected to your computer, so you’ll need to find the “category” your suspect driver falls into. Double-click on the suspect to open the Properties dialog box. Under the Driver tab, you’ll find a button labeled “Roll back driver.” This option should uninstall the suspect driver and reinstall the next most-recent version.

If this seems like a lot of work, it is. That’s why I recommend Driver Detective as an alternative to maintaining your drivers manually. Driver Detective will seek out, download, install and maintain a copy of the current driver, as well as historical drivers that enable you to roll back to an earlier version. If your current driver becomes corrupted, Driver Detective has everything on hand to reinstall a fresh copy of the driver automatically.

On Tuesday, Microsoft released the long awaited kernel mode driver patch that will close the Duqu vulnerability. The Duqu worm has been making the rounds for several months and takes advantage of a weakness in the True Type Font engine. Last month, as a temporary fix, Microsoft distributed a workaround that basically disabled the vulnerable code.

Duqu Shares Some Traits of Stuxnet

In the months that it was in the wild, Duqu was widely distributed throughout Europe and the United States. The vulnerability was particularly troublesome because it will allow a malefactor to gain administrative access to an infected computer, and will allow the installation and execution of software, administrative tasks like account creation and the compromise of user data.

The Patch Tuesday delivery contained 13 updates for various flaws. Originally, Microsoft planned to roll out 14 patches, but one was pulled back to address some compatibility issues. With Tuesday’s rollout, Microsoft has delivered 99 updates so far in 2011. The company hasn’t necessarily closed the books on updates, though. Microsoft often issues a minor “Patch Tuesday” on the fourth Tuesday of the month, which this year falls on December 27.

In addition to putting the brakes on Duqu, Microsoft addressed 18 other known vulnerabilities in 12 patches. Those vulnerabilities included critical or important holes in Active X, Windows Media Player/Windows Media Center, Microsoft Office, Microsoft Publisher, Microsoft PowerPoint, Microsoft Excel, Microsoft Active Directory and Internet Explorer that could potentially allow the execution of code by a remote user. Microsoft also fixed “important” vulnerabilities in Office, the client/server runtime system and the Windows kernel that could allow a malicious user to gain additional privileges.

Microsoft also took the opportunity to release a new version of the Microsoft Windows Malicious Software Removal Tool, presumably equipped to do battle with Duqu. The worm was officially discovered on September 1 by researchers at the Budapest University of Technology and Economics. Despite the Star Wars-esque sounding name, the Budapest researchers named the worm based on files the malware creates, which are prefixed with the characters “-DQ.”

Despite extensive research, Duqu’s purpose isn’t known. The worm bears a strong resemblance to Stuxnet, and was originally mistaken for Stuxnet by some Internet security firms. Like Stuxnet, Duqu makes use of stolen signed security certificates and also appears to uninstall itself after 36 days of active infection. Attacking servers have been found in Germany, Belgium and China, but security experts are still unsure of Duqu’s intended targets.
