It's been a busy week for anyone obsessed with operating system upgrades. Microsoft released Windows XP SP3 to manufacturers, Canonical launched Ubuntu 8.04 Hardy Heron, and OpenSUSE 11 came one step closer to release. But this week's software news wasn't all operating systems, all the time. Here are a few of our favorite stories from the week that was:

DRM strikes again: MSN Music customers left in the dust

In case you haven't heard, DRM kind of stinks. Sure, copyright holders want to be able to profit from their music by making sure you don't make copies for all of your friends. But when companies like Microsoft come out and tell you they won't support your licenses after August, it just means you can't listen to music you've already paid for on multiple devices anymore.

AVG Free 8 adds anti-spyware protection

Who says there's no such thing as a free lunch? Well, lots of people. But anyone who's tried AVG Free knows there is such a thing as a good anti-virus application. The latest version adds a bunch of new features like anti-spyware, anti-rootkit, and linkscanning protection.

A few months ago, Grisoft updated its AVG anti-virus suite to version 8 and bundled linkscanning, anti-spyware, and anti-rootkit software to boot. Now Grisoft's popular freeware anti-virus application is getting some of the same features. AVG Free 8 is out, and not only does it protect your system from viruses, but you get spyware detection as well.

AVG Free 8 doesn't have all of the features you get in the commercial version of the application. There's no rootkit protection or linkscanner. And there's no email or instant messaging integration. For those features you'll have to shell out $35 or $55 for the standard or "internet security" versions. But as freeware antivirus applications go, AVG is packed with features like real-time protection, daily updates, and complete system scans at regularly scheduled intervals.

Update: As several readers have pointed out in the comments, when you install AVG Free 8, you will likely find a bunch of advanced features like linkscanning and email protection. The AVG web site has a comparison chart showing that these features are included in the commercial version but not the free version. It's not clear if Grisoft is including free trials of these functions or if the chart is wrong.

One of our biggest complaints with Windows Vista is that it takes far longer to boot up and shut down than Windows XP installed on an identical system. When Microsoft first announced the feature set for Vista, one of the things they claimed was that you would actually have shorter startup times, but we later discovered that what they meant was that there would be power saving features that would make it easy to put your PC into sleep mode when you're not using it and quickly resume.

But if you're a Vista user that likes to completely shut down your computer, you've probably gotten used to waiting a while for it to start up when you next hit the power button. It turns out that part of the problem might not be with Vista itself, but in 3rd party software that doesn't play well with Vista. For example, although we've long been fans of AVG Free Edition anti-virus software, Ed Bott and Dwight Silverman both suggest that it could have a dramatic impact on Vista startup times.

So we went ahead and uninstalled AVG and lo and behold, our system did seem to boot up more quickly. Of course, there are various ways to measure boot speed. For example, you could stop the timer when you first see your Windows desktop. But for many users, what really counts is the moment when you can start clicking on programs and expect them to respond or the moment when your internet connection is ready, allowing you to launch a web browser, chat program or other online applications. And we have to say, the time between the desktop showing up and our internet connection working has gone up significantly since uninstalling AVG.

Our tests were completely unscientific, so we don't have a lot of numbers to share with you. And our system still takes 80 to 90 seconds to startup with Vista, while we can boot Windows XP on the same system in about half the time. But now we're curious. If you're using AVG on Vista, have you tried uninstalling it to measure the impact on your startup times?

We still highly recommend AVG Free if you're using Windows XP. But if you're using Vista, you might want to check out some free alternatives like Avast!, AntiVir, BitDefender, or ClamWin.

PCLive Security is a full featured security suite for Windows. It helps protect you from viruses, spyware, rootkits, keyloggers, and adware. Oh yeah, and it happens to be free. While there are several other free security applications out there, none come with quite so many features in one package.

PCLive Security includes the ClamAV antivirus engine, a bi-directional firewall, and a pop-up and adware blocker.

There's also a paid version that includes technical support, hard drive maintenance, and file optimization features for $4.95 per month.

PCLive Security runs on Windows 2000/XP/Vista machines. On the downside, the installation process takes forever, and once PCLive Security is up and running it seems to be a bit of a resource hog. Oh yeah, and it will try to uninstall any other anti-virus software on your PC when you run the installer.
