Windows 7 may not be rock solid, but it is one of the more stable Windows releases since Windows XP reached maturity after SP2. I remember thinking this as I ran the beta for an entire year prior to the initial release, with very few issues to speak of.

That was then, and today a new generation of hardware and software has been set loose on the landscape with a new set of compatibility issues that Microsoft is attempting to keep up with. The result is a potentially unstable experience.

No need to worry; there are plenty of steps you can take to avoid system instability. In fact, Windows makes it possible to make your experience pretty darn rock solid.

Here are some tips to help you improve Windows 7 stability.

Keep Windows Updated

Microsoft is constantly coming out with software updates for its operating systems, supporting programs, and various hardware drivers. Whether you run Windows XP or Windows 7, the one thing you can count on is Microsoft sending updates down the line on a regular basis — at least until the OS falls out of support.

Keeping your operating system updated is paramount to long and healthy system operation. Windows is impacted by a nearly infinite number of possible issues that spring up as software and hardware engineers continue to refine their products. Each revision adds to the potential of a domino effect that may result in system failure.

Keep Drivers Updated

Keeping your hardware drivers updated means doing more than just running Windows Update now and then. Sometimes, you need to get the update directly from the manufacturer’s website. It’s usually a good deal to make a list of the various hardware inside of your computer, and make check for new drivers on a monthly basis.

This can be the difference between that new feature in DirectX working or not working on your video card, or a Windows update resulting in unexplained hangups.

Perform Regular Maintenance

In order to keep your system running like a champ, it’s a good idea to take a moment to perform regular maintenance beyond system and driver updates. Defragmenting your hard drive, cleaning unnecessary files out of temporary folders, and even cleaning the inside of your computer can make a big difference in performance and stability.

Over time, your computer’s fans can become covered in dust and other debris that are floating through the air. This buildup reduces the efficiency of the fans, which may lead to overheating. Heat is one of the leading causes of hardware failure, and can shorten the life of your computer considerably.

If you’re running high-end hardware, make sure you have a computer chassis and fan arrangement intended to keep high-end hardware cool. Running an overclocked CPU under a stock cooler can be a failure waiting to happen.

Only Use Software You Trust

Downloading programs off the Web because they promise to optimize your registry or free your system of ooglie booglies that mean it harm can be a bad idea. The same can be said for pirated software, media players that promise you the best of free adult entertainment, and anything else that throws itself at you as you peruse the nether regions of the Information Super Highway.

The best rule to abide by when considering downloading software is to only do so if you either recognize the brand, or the source. For example, I’d be more inclined to try a piece of software if it comes from Steam, or MacHeist than some unknown site that looks like it was designed by a seven-year-old.

Limit the Amount of Things You’re Running

Having too much going on at once can cause a traffic jam as information races back and forth between your hard drive(s) and your processor(s). If your CPU is running close to capacity, you’ll probably find things a little less reliable than they would be if you just had one or two programs running.

If things start to get a little sketchy, try closing tabs in your browser or exiting out of programs you’re not using at the moment. You may find that this brings things back to normal.

Stick to Tasks Your Hardware Can Handle

Perhaps one of the most obvious (yet often overlooked) causes of Windows failure is attempting to run programs that your system just can’t handle. Netbooks might be able to run Windows 7 just fine, but if you try to edit HD video or play a high-end first-person shooter, you’ll probably experience some system instability.

To paraphrase a sentiment once made in the halls of Congress, your computer is a series of tubes. Even if you have 64-bit tubes, there’s a chance that you can overload the system. Imagine that your computer is a water company, and your browser is the average household. Each individual house uses a certain amount of water based on the people (tabs) inside.

Now, let’s say your system can handle a few houses (programs) that use a minimal amount of your resources. You can handle these without any great stress on the resource, though if you add a skyscraper to the mix (HD video editing), you’ll probably overload your resource and one of your customers will probably go without.

In this sense, your computer really is a series of tubes. Stick to the programs your computer can handle, and consider upgrading the hardware when your needs evolve into operations that require a little more processing punch.

Don’t Fiddle With It if You Don’t Know What It Does

Every geek wants to be a computer ninja. The fact is, not everyone knows the ins and outs of the registry and various system calls. Fiddling with system files and attempting to perform a complex workaround to get software to do something it isn’t designed to do can certainly increase the likelihood that your Windows machine will become unstable.

Killing processes in the task manager without knowing exactly what a particular process is can result in a system crash if you stop the wrong file. Take a moment to search for the process name and investigate exactly what it is, and what it does before ending it.

It could be said that the best tool to increase your computer’s stability is education.

What about you? How do you keep your Windows machine stable?
