Project #1: Get Windows in Gear
Start With a Backup
All PC tweaking begins with a backup, even if you simply create a new restore point. To set one in XP, click Start, Programs (or All Programs), Accessories, System Tools, System Restore, choose Create a restore point, click Next, and step through the wizard. In Vista, click Start, Programs (or All Programs), Maintenance, Backup and Restore Center, select Create a restore point or change settings, choose System Restore, click Next, and then follow the on-screen instructions.
Restore points won't solve all your problems. That's why one of the most welcome new tools in Vista is Complete PC Backup, which creates a snapshot of your machine, including all of your applications, settings, and data files. Later, if (when?) your hardware fails, you can restore the entire system, not just your files. (Note that Complete PC Backup is not available in Vista Home Basic or Home Premium.)
To create a backup, click Start, Control Panel (or Start, Settings, Control Panel on the Classic Start menu), Back up your computer (in Classic View, double-click Backup and Restore Center). Choose Back up computer and follow the steps. I recommend making a backup at least once per month if you use your PC for work, and a minimum of once every six months no matter how much or little you use it.
Always back up before you make any big changes to your PC's configuration (note that Windows creates a restore point automatically prior to every new software installation and any other significant system change).
Stop Unnecessary Startups
Whenever you start your PC, various services and programs start up in the background, often without your knowledge. Most of them are programs or services you need, such as your firewall and antivirus software. But some, such as instant messaging apps that you rarely use, do nothing but squander system resources and slow down your PC.
The simplest way to remove the autostart apps you don't use is with the System Configuration utility: Click Start, Run (or just Start on Vista's menu and type in the Start Search box), type msconfig, and press <Enter>. Select the Startup tab to see the programs that start with Windows. Uncheck those you don't want to run (see FIGURE 1
Keep an Eye on Performance
The best way to find out how well your system is performing is to run a diagnostics program. The counters in XP's System Monitor utility provide insight into your PC's operation, but they can be difficult to decipher. To run the program, click Start, Run, type perfmon, and press <Enter>. Select System Monitor in the left pane, and click the plus sign in the toolbar on the right to add more performance measures.
Vista's Reliability and Performance Monitor is a big improvement over XP's System Monitor. Click Start (or Start, Run on the Classic Start menu), type perfmon, and press <Enter> to open it. The utility is actually several tools in one, but its most useful feature is the Resource Overview, which provides a graphic representation of your current CPU, disk, network, and memory use, as well as historical usage stats (see "The Best of Vista's New Tools"). The program provides exceedingly detailed information about each measure; for example, in the CPU section you can see every service and application running, how many threads each is using, and the CPU use of each.
Click Reliability Monitor in the utility's left pane to view a day-by-day history of your machine's stability, including itemization of any system crashes and hardware or software failures. You can even drill down for more details about any individual event. The tool also computes an overall reliability index, which changes every day to reflect whether your system or applications have crashed.
Restore Files via Shadow Copies
Another of my favorite new features in Vista Ultimate and Business is Shadow Copies, which backs up your files automatically and makes restoring previous versions of files gone bad a breeze. To revert to a previous version of a file, open Windows Explorer, right-click the file, and select Restore previous versions. Click one of the listed versions to open it.
Keep a couple of things in mind about this feature. First, Vista doesn't maintain a shadow copy of every version of the files you open; instead, each time Vista creates a restore point, it generates a shadow copy. Also, some of the versions you see listed may have been created when you used Vista's Complete PC Backup program.
Tweak Your Associations
By default, Windows associates certain files with certain programs: When you double-click the file, a specific application opens to run it. But why stick with Windows' choices? To change the program associated with a specific file type in XP and Vista, right-click the file in Explorer or any folder window, and select Open With to produce a list of programs that can run that file. Select Choose Program in XP, or Choose Default Program in Vista. In the resulting dialog box, click the program you want to use as the default, and make sure to check Always use the selected program to open this kind of file. Then click OK. If the program you want to use as the default isn't listed, click Browse, locate and select the program you want, click Open, and then click OK.
