Device Doctor is a Free Driver Update Scanner with Promise [Downloads]
Windows only: Driver update utility Device Doctor finds outdated drivers on your PC, and helps you download the latest version—without charging you a dime.
Using the utility, which can be installed or used as a portable application, is about as easy as it gets—just click the Begin Scan button, wait a couple of seconds, and you will be shown a list of drivers that can be updated. The download button for each driver will take you to their web site, where you can download the drivers for free, without signing up for anything at all. Most of the drivers come with setup programs, but some of them are nothing more than zip files, and would need to be installed manually—hopefully something they can improve on in the future.
During our testing, we used the application on half a dozen PCs, and had varied results—on our XP test system, Device Doctor worked well and accurately found new drivers, but for Windows 7 we didn't have as much luck, with a few incorrect drivers being thrown at us. That said, Windows 7 was only released recently, so expect that support to improve in the future.
Device Doctor isn’t perfect yet, but as a completely free, portable application that you can toss on your thumb drive, it’s well worth a look. It might even save you some time searching for new drivers while you are fixing mom’s PC.
Device Doctor is a free download for Windows only. Be sure to check out the full How-To Geek review for a more in-depth look, as well as instructions on installing drivers manually.
Sumatra 1.0 is a Blazing Fast Replacement for Adobe Reader [Downloads]
Windows only: The Sumatra PDF Viewer is a tiny, open-source, portable, and, most of all, lightning-quick replacement for the bloated Adobe Reader we’ve all learned to replace. It’s only a 1.2 MB download, so why not give it a try?
Sumatra opened every PDF we threw at it without any issues, along with a table of contents in the left pane if available. You can head into the Options to choose the default layout and zoom, or choose whether to have the sidebar display automatically. Want to copy text to the clipboard? Just hold down the Ctrl key and select the text with your mouse, then use Ctrl+C to copy it. There’s even a full set of hotkeys, including Gmail-style navigation. It’s not as full-featured as Reader or Foxit, but if all you are doing is reading PDFs, it’s definitely worth a look.
With giant hard drives and dirt-cheap memory these days, perhaps the biggest reason to switch to an alternative to Adobe Reader isn't even the bloat anymore—it's the non-stop security holes that seem to plague the popular reader, leaving you vulnerable to drive-by attacks. If Sumatra isn’t for you, at least check out one of the other five best PDF readers.
Sumatra is a free download for Windows only. If you plan to keep Adobe Reader installed, be sure to check out the manual for instructions on using Sumatra as your default viewer when reading PDFs from the web.
Close All Windows from the Windows 7 Taskbar [Downloads]
Close All Windows is a simple application that forces all your open windows to quit immediately, and the Addictive Tips blog points out that you can also pin it to the Windows 7 taskbar for quick access.
All you really have to do is download the application, save it into a permanent location somewhere on your drive, and then pin it to the taskbar using a simple right-click -> Pin to Taskbar—just make sure that you don't double-click the application, or all your windows will immediately close. Unlike some of the other similar applications we’ve written about, this one has no interface, but it has a higher resolution icon that looks good pinned to the taskbar. If you are looking for a way to immediately close all your running applications, this could do the trick nicely.
Close All Windows is a free download, works on all versions of Windows, but will need to be pinned to the Quick Launch instead of the taskbar in XP or Vista.
Process Hacker is a Powerful Task Manager Clone [Downloads]
Windows only: System information utility Process Hacker is an open-source, portable task manager clone with loads of powerful features.
While Process Hacker is meant to look and work a little more like the built-in Task Manager, being easy to approach for regular users, it actually has many of the same features as the popular and powerful Process Explorer that we all know and love.
Along with the normal features one would expect from a process manager utility, you can add or delete services, read and write process data memory in a hex editor, search through memory with a regex, inject DLLs into running processes, and pretty much every other feature you can imagine. Process Hacker is free and open source, available for Windows only.
Radio Sure Streams and Records 12,000 Radio Stations [Downloads]
Windows only: Pared-down portable application Radio Sure streams and records more than 12,000 channels of music and other radio feeds. If you can’t find something to listen to, you’re probably not looking hard enough.
The interface of Radio Sure is straightforward, if a bit cluttered. It starts with a master list of radio stations and a search box to narrow down the stations by genre, country, language, and other name. At the bottom of the window are some basic controls for playing and recording the streams, as well as information about the song if it’s embedded in the source. If you’re looking for even more online music, check out our feature on downloading and listening to free music on the web. If you have your own favorite means of streaming radio wherever you are, share in the comments below.
Portable Ubuntu Runs Ubuntu Inside Windows [Downloads]
Windows only: Free application Portable Ubuntu for Windows runs an entire Linux operating system as a Windows application. As if that weren’t cool enough, it’s portable, so you can carry it on your thumb drive.
Built from the same guts as the andLinux system that lets you seamlessly run Linux apps on your Windows desktop, Portable Ubuntu is a stand-alone package that runs a fairly standard (i.e. orange-colored, GNOME-based) version of the popular Ubuntu Linux distribution. It just doesn’t bother creating its own desktop, and puts all its windows inside your Windows, er, windows.

The coolest parts about Portable Ubuntu are:
- It actually works (in most cases, on most systems).
- It fits on a (larger) thumb drive and can run entirely from it.
- It can work on, and save to, your Windows folders and files.
- It’s persistent, so changes you make and apps you install are carried around with you.
- It’s easily manageable from Windows, and works great on dual monitors.
Wanna give it a go? Grab the latest Portable Ubuntu package (about 438MB as of this writing), then double-click to unpack it to a folder. On Vista or Windows 7, you’ll have to open your command prompt as an administrator (hit Windows key, type in cmd, then right-click on the “Command Prompt” option that appears and select “Run as Administrator”); on XP, you’ll probably just have to launch a command prompt. Head to the folder where you extracted your Portable Ubuntu, and enter run_portable_ubuntu and hit Enter to launch the .bat script.
Your machine will whir and decompress for a while, and you’ll likely get a few prompts to “Unblock” coLinux and a few other apps’ abilities on your system. Unblock all of them, and you’ll eventually get a small, move-able menu bar on your desktop, as seen in the top screenshot. Drag this wherever it’s comfortable to keep it, and you’re on your way.
From those three pop-out menus—Applications, Places, and System—you can accomplish pretty much the same thing as any Linux user can, just without the full desktop. Launch a program, and it appears in a window that looks like any other on your Windows system. Open a file browser from "Places," and you can get to your Windows files by heading to /mnt/C (or substitute your drive name/letter for “C”). Feel free to carry around Audacity, GIMP, or any other editing programs that lack a Windows equivalent and start getting creative with them.
Whatever changes you make to your system stick with it. So if you, say, want to install VLC media player for some on-the-go media, you can install it from the Add/Remove dialog or tackle it manually in Accessories->Terminal, and it'll be planted right in the Sound & Video menu. The same goes for system tweaks or startup apps you add to your little Ubuntu package.
Update: For those who miss it over at the Portable Ubuntu page, the default root password is 123456.
Portable Ubuntu makes for a great place to test out your more cutting-edge stuff, without having to worry about messing up your working Windows system. The latest beta of Firefox 3.1/3.5? Even easier to run than the portable solution, and you can keep both your Windows and Portable-Ubuntu-launched Firefox browsers open at once.
When you’re running Portable Ubuntu, Windows treats it like any other program. You can close down individual app windows from your taskbar, and pop it onto and off your desktop with little hassle.
Portable Ubuntu is a free, portable download that runs from Windows systems only. Drop your Linux-inside-Windows ideas and other geeky stuff in the comments.


It's the little things that make a Windows system great—like utilities that use less than 10MB of memory to make your life easier. Here are 10 apps that pack a lot of greatness into very little space.
You don’t open your programs in the order you want them nealy arranged on your taskbar, you open them when you need them. Taskbar Shuffle knows this, and makes it easy to quickly swap windows around, along with system tray icons. It also allows you to close out windows with a simple middle-click, which alone could make it worth the roughly 6MB price of admission. You won’t know you wanted to fling windows out of your cursor’s way until you try it.
It’s probably smaller than your desktop wallpaper. But Everything is more useful and efficient than applications 25x its size. Everything only searches through file names, not inside the contents of them, but it does so stupid-fast as you type. You’ll usually find your file with a few keystrokes, and Google fans will appreciate the boolean operators that enable and/or elegance. Definitely an app you’ll want to right-click and create a keyboard shortcut for. There’s also
If you’re rocking dual, triple, or even quadruple monitors at home or at the office (and, let us just say, lucky you on that last bit), these apps have a relatively small system footprint, but make a big impact in how your system looks. They both manage separate or split wallpapers across multiple monitors, and can grab and rotate images from your computer, Flickr, or other sources. With DisplayFusion’s
I know, it's like we never give up on promoting this, right? Well, what can we say—we (the royal "we," really) wrote it because it filled a need in our half-breed lives of alternating text and HTML. Turns out, though, that folks ranging from power emailers to military writers have found dull, boring text they can automate, misspelled words to catch on the fly, or perhaps powerful, seriously secretive acronyms they'd occasionally like to spell out. For less than 2.5MB of RAM on most systems, this one packs a pretty hefty punch.
In a magical world without computer stress, we’re all running virtual machines to try out software we might not want, and we simply uninstall it there, keeping one system nearly pristine. For the real world, Revo Uninstaller scrubs an application and all its traces off your Windows system. It can also turn off programs that are starting up with Windows, and uninstall applications with a crosshair “Hunter Mode” that doesn’t require you to know what it’s named.

Windows Task Manager isn’t a bad tool, necessarily, but it only gives you a layman’s view of what’s eating up memory or pulling serious CPU cycles. Process Explorer expands on the vagueries of “rundll” or “svchost” with a double-click, links background services to applications, and points to the folders they come from. You might not need it all the time, but when you’re rooting around and trying to
There are a lot of good reasons to keep on rockin' Windows XP, but some of the built-in utilities can feel a bit, well, dated—and that goes for a good number of Vista tools, tool. Notepads without tabs? A Paint app that can't really resize or undo more than one action? Skip the headaches and work-arounds and run down our list of
