If you want to share information stored on your computer with other people nearby and everyone’s computer has a wireless network adapter, a simple method of sharing is to set up an ad hoc wireless network. In spite of the fact that members must be within 30 feet of each other, this type of network presents a lot of possibilities. For example, you might consider establishing an ad hoc network at a meeting of mobile computer users so that you can share information with other attendees on their own screens rather than an overhead projector. (After establishing the network, you can do this by using Windows Meeting, for instance.)
Ad hoc networks are by definition temporary; they cease to exist when members disconnect from them, or when the computer from which the network was established moves beyond the 30-foot effective range of the others. You can share an Internet connection through an ad hoc network, but keep in mind that the Internet connection is then available to anyone logging on to a computer that is connected to the network, and thus is likely not very secure.
To set up an ad hoc network:

Windows Vista includes a command line tool, Powercfg.Exe, that you can use to configure power management settings. Windows 7 introduces a new switch, /energy, to provide a comprehensive report of those settings. It also offers diagnostics that can indicate which applications or devices might be causing power management issues (such as a USB driver not entering suspend) and what power management settings you can configure differently for better results. At an elevated command prompt, simply enter:
POWERCFG –ENERGY –OUTPUT
The tool will observe your computer for 60 seconds, and then create a file called ENERGY-REPORT.HTML in the path you specified. Simply double-click on this file to see what’s going on.

With the releasing to manufacturing of Windows 7 on July 22nd, 2009, Microsoft has started updating all the resources adjacent to the operating system also to the RTM milestone. It is the case of Windows Driver Kit Version 7.0.0. Developers are now able to grab an updated version of Windows Driver Kit Version 7.0.0 specifically tailored to the gold development build of Windows 7. Starting with the first half of August 2008, software developers have available the resources necessary to build drivers for Windows 7 RTM Build 7600, but also for previous releases of the Windows client and server operating systems.
“The Windows Driver Kit (WDK) Version 7.0.0 contains the tools, code samples, documentation, compilers, headers and libraries with which software developers create drivers for Windows 7, Windows Vista, Windows XP, Windows Server 2008 R2, Windows Server 2008, and Windows Server 2003. This development kit does not contain device drivers for your personal computer,” reads an excerpt from the overview for Windows Driver Kit Version 7.0.0.
But in addition to the WDK, Microsoft has also updated the documentation made available for developers in order to better leverage the resource. While WDK for Windows 7 RTM has been live for a few weeks, the updated documentation was only offered to devs on August 14th, 2009. The Windows Driver Kit documentation is currently available for download and integration with Windows 7. Read More»

Whether you’re dealing with users in your work environment or kids at home, being able to control what applications a user can use can prevent a lot of hassle and headaches. Windows 7 includes a new tool, called AppLocker, that lets you do just this by creating a policy to specify exactly what applications a user is allowed to run.
To access this feature, click start and enter Gpedit.msc. Then navigate to Computer Configuration | Windows Settings | Security Settings | Application Control Policies. Expand the Application Control Policies node and highlight AppLocker.
Here you can configure Executable Rules, Windows Installer Rules, and Script Rules. For example, highlight the Executable Rules node and right-click to select Create New Rule. You can then create a rule allowing or denying access to an executable based on such criteria as the file path or publisher.
And in case you’re in a hurry, AppLocker will let you apply default or automatic rules. There are a lot of options exposed in AppLocker—too many to cover in a short tip—so you’ll have to play around with it some to get a better idea of just how much this tool can do. Read More»

It’s always a bit tricky to beta test a new operating system. Most of us don’t have an abundance of extra hardware just sitting around, and it can be both time consuming and risky to rebuild your production machine with a pre-release version of the next OS.
But with Windows 7, it’s pretty easy to beta test on the machine you’ve already got. Hard drives have gotten much larger and much less expensive, and if you’re running Windows Vista, you already have built-in functionality to help you create a separate partition for testing.
To get started, open the Disk Management section of the Computer Management console on your Windows Vista machine. You can access this by clicking Start | Run and entering compmgmt.msc. Right-click your current system partition, likely labeled C:, and select Shrink Volume. Windows will query the disk for the amount of available space. You’ll probably want at least 20-30gigs of free space so you’ll have enough room for the Windows 7 beta installation, some data, and a few applications. Read More»

Say you’re doing a project for school, a presentation, or you simply need to get a hold of an application’s original (512 x 512) icon. Searching Google Images may do the trick, but you’ll often find yourself with pictures that are too small, blurry, modified or just not the one you’re looking for. This short guide will show you how to get your hands on an application’s original icon, right from within itself.
Power users should know that most Mac OS X apps (be they Apple-developed, or created by third-party devs) contain something called a “Resources” folder. This folder is mostly used by the application itself to get the images and sounds it needs to display / play throughout the course of running. Yes, you’ve guessed right: this is the place you need to be to start looking for that app’s icon set. We’ll use Apple’s GarageBand as the example for this short tutorial.
1. The first thing you need to do is navigate to where GarageBand is installed on your computer. If you have it already living peacefully in your Dock, just right-click its icon and select “Show in Finder.” Whether or not you’ve placed the music-making program in your Applications folder, you can simply fire up Spotlight (CMD + Space) and do a quick search to locate the app. Hold down the Command (CMD) key and hit Return (Enter) with the GarageBand selected in Spotlight. Congratulations! You’ve found where GarageBand is situated on your Mac’s hard drive.

One way to speed up your computer is to increase your hard drive’s performance. If you’ve been using your computer for a while, you’ve probably noticed that your computer is getting slower. One reason for this is that your hard drive has gotten more fragmented over time.
This means that as you install and delete things from your hard drive, holes are being created and filled randomly with other files so, say, your video of Madonna might be broken up into thirty pieces all over your hard drive, slowing down its playback.
Well, Windows XP has a Disk Defragmenter that will solve all your woes. It takes the pieces of each file and puts them together again so they can be read in one clean pass.
Be sure to run this program at night since it takes several hours and make sure to close any open programs. Go to Start->All Programs->Accessories->System Tools->Disk Defragmentor to access it.
Click the Analyze button. It’ll tell you if you need to defragment your hard drive.
A lot of red is a bad sign. If it says “You should defragment this volume”, click the Defragment button. Come back in a few hours, and your hard drive should be purring.
