Top 10 Windows XP Tips Of All Time

Tip 1: Automatically log when and why shutdowns have occurred.

Love it or hate it, Windows XP is undeniably more stable than its predecessors. But it still crashes, and it still has occasional trouble shutting down. This registry hack logs all shutdown errors, telling you when, where, and why strange and annoying things have happened.

Some folks have the luxury of packing their buggy PC off to a help desk. But if you like to get your hands dirty, consider this essential tweakage.

Here's how to set up logging for unexpected system shutdowns:

1. Open RegEdit and browse to HKEY_LOCAL_MACHINE\SOFTWARE\Mico****t\Windows\Curr
entVersion\
Reliability

2. Set the ShutDownReasonUI data value to 1. (If this string doesn't exist, create it and set the value to 1.)

3. Exit RegEdit and reboot your PC.

Tip 2: Recover lost data.

Everyone has accidentally deleted files from their hard drive, and very few feelings are as low as the moment right after you nuke 300 irreplaceable photographs of your kids/dogs/life. Actually, one feeling is worse than that: accidentally quick-formatting your entire drive.

Even if you regularly back up your drives, mistakes happen. That's why this tip is paramount. It's also really simple. There's an excellent downloadable data recovery app for XP called Zero Assumption Recovery that can help. Don't waste another minute — download and install it now.

When you run into trouble, here's what to do:

1. The moment you delete your data, stop using your hard drive. Don't save or install any new applications — they'll be written over your recently departed data.

2. Run Zero Assumption Recovery. You already had it installed, right?

3. Select the hard drive you want to scan. Wait for the scan to finish. (This can take between one and two hours -- part of Zero Assumption Recovery's effectiveness is its thoroughness.)

4. With any luck, you'll see a list of your missing folders and files. The freeware version of Zero Assumption Recovery allows you to recover up to four folders per scan. If you pay $100 for the full version, you get full recovery.

Note: You can also use Zero Assumption Recovery to recover deleted photos from your camera's memory card.

Tip 3: Stay on top of registry changes.

Given the power and flexibility of Windows XP's registry (and the large number of registry hacks in this Top 10), it's no surprise that the number 3 XP tip involves keeping track of any and all changes made to your registry.

But given the prevalence of spyware, rootkits, and other malware these days, knowing what you've done to your registry is a secondary concern to knowing what other applications are doing to it.

For peace of mind — and occasionally, for curiosity's sake — we consider SysInternal's Regmon an essential piece of our OS. It's a freeware application that allows you to browse through all the keys in the registry, filtering in a variety of ways to pinpoint specific registry changes.

For example, you can quickly filter for certain applications. If you're having trouble with Windows Media Player, you click on the Options menu, then Filter. At the menu, type wmplayer into the Include field. When you see the resulting list, you can double-click any entry to open up its registry value.

Because you can search and filter, Regmon is also an excellent method for tracking down hard-to-find registry items.

Tip 4: Set a custom resolution.

Notice a trend in the second half of this story? If you answered, "They're all registry hacks," you are correct. Windows XP's registry loads an amazing amount of flexibility and customization in a fairly low-risk package.

Tip number 4 on our list is another one of our favorite registry hacks. Windows XP allows you to specify a large number of set screen resolutions based on what types of images your display can accept. However, in a few rare instances, you may want to specify a non-standard resolution for a clearer or more accurate picture. This tip allows you to do just that. It's one of those tips that doesn't seem all that handy — until you desperately need it. Plus, it's just plain cool. If you have a wonky projector or TV screen you want to use with a laptop or PC, you might want to give this a try.


Here's how it works:

1. Open RegEdit and browse to HKEY_CURRENT_CONFIG\System\CurrentControlSet\Contr
ol\VIDEO\
{the address of your primary video card...it often begins with "23A77BF7"}\0000\

2. The Default Settings.XResolution data value is the horizontal resolution, and the Default Settings.YResolution data value is the vertical. Double-click the Default Settings.XResolution data entry, select the Decimal radio button, and in the Value Data field, enter your desired horizontal resolution. Then do the same with Default Settings.YResolution to change the vertical resolution.

3. Exit RegEdit and reboot your PC.

If you're scared of tweaking your registry on this one, a handy app called PowerStrip ($29.95, available for a free try-before-you-buy download), allows you similar resolution-changing functionality.

Tip 5: Automatically optimize your hard drive.

One of the keys to system performance is an optimized hard drive. Typically, you optimize your hard drive using Windows' Defrag utility. But there's a great registry hack that will force Win XP to automatically optimize the location of files when your PC is idle. Here's how it works.

1. Open RegEdit and browse to HKEY_LOCAL_MACHINE\SOFTWARE\Mico****t\Windows\Curr
entVersion\
OptimalLayout

2. Find the string called EnableAutoLayout, and change its data value to 1. (If this string doesn't exist, create it and set the value to 1.)

3. Exit RegEdit and reboot your PC. Done!

Tip 6: Force unresponsive applications to close at shutdown.

When it comes to balky PCs, few things annoy us more than the moment when we try to shut down Windows and it tells us it can't because some crashed application isn't responding, and that we have to do it ourselves by clicking the End Now button.

This registry hack changes that. Here's how it works.

1. Launch RegEdit (select Start > Run, type regedit and click OK) and browse to HKEY_USERS\.DEFAULT\Control Panel\Desktop

2. Find the string called AutoEndTasks. Right-click it, select Modify from the pop-up menu, and change the data value from 0 to 1. (If you can't find this string, create it by selecting Edit > New > String Value and set the data value to 1.)

3. Close RegEdit and reboot.

Tip 7: Run two displays on the same PC.

This tip is for the worker bee. Adding a second display to your PC won't quite double your productivity, but it will make your computing life easier. Walk around a cube farm these days, and you'll likely see at least a few power users doubling up.

Thankfully, Windows XP makes it extremely easy.

1. Plug the second display into your computer. (Many video cards today have a second Video Out port; if not, you'll have to install a second video card.)

2. Right-click on your desktop and click Properties to bring up the Display Properties window. Click on the Settings tab.

3. See the grayed-out box to the right of the black box? That's your second monitor. Click on it and then click the check box next to "Extend my Windows desktop onto this monitor" to enable it. From here you can adjust the resolution of the secondary display. The goal here is to have a desktop that spans both of your displays, so if your second screen is physically located to the left of your primary one, drag and drop the #2 monitor to the left of the #1 display.

Tip 8: Scrub your hard drive clean.

Windows Support Tools, provided free by Mico****t, are a suite of some 20+ separate applications that are extremely handy for a number of uses. Ordinary PC users probably won't use many of these apps — they're mostly used by IT pros to troubleshoot and analyze Windows XP. But even if you're not an expert, don't be afraid of using the Windows Installer Clean Up Utility, which will help you remove all leftover files from a failed uninstall of a Windows Installer application.

Download Windows Support Tools from Mico****t's Download Center. (If you're curious about the other apps in the suite, check out the help file included in the Windows Support Tools Program group.)

To run the Windows Installer Clean Up Utility, go to the command prompt (select Start > Run) and type msicuu.exe. You'll see a list of all applications with uninstall data. Select the ones you want to get rid of and click the Remove button. Obviously, you want to use caution here — don't clear the install data for an application unless you're absolutely sure you won't ever need it.

Tip 9: Increase available disk space by scaling back System Restore.

It's not perfect, but Windows System Restore is a useful first step in recovering your PC or drive from a major system error. However, it can consume more than 10 percent of your total hard drive space.

If you find yourself desperate for an extra few gigabytes — particularly on secondary storage drives — there's an easy way to reclaim data space by simply limiting the number of System Restore points Windows XP establishes. This one's a snap and there's no tangible increase of risk, which is why we love it.

1. Right-click on My Computer and select Properties > System Restore.

2. If you have just one hard drive, skip to step 3. Otherwise, select the drive on which you want to gain storage space and click the Settings button.

3. Adjust the slider to the left to use less disk space, and Win XP will reduce the number of System Restore points by the appropriate amount.

tips 10:This tip is one of our favorites because it always works. Running in the background of Windows are scores of services, small processes used by Windows and many Windows applications. The thing is, you don't need all these services — especially for applications you never use — and many of them actually slow your PC down.

Win XP power users have long known that you can easily eke a little extra performance out of your PC by disabling services that are completely unnecessary or that don't need to be running all the time. Here's how it works.

1. Click Start > Run, type services.msc and click OK. This will bring up the Services management console. Click on the Extended tab at the bottom of this window; each background service running on your PC is listed here. Windows includes a fairly detailed description of each service; simply drag the Description column wider to read more of each description, or click on a service to see its full description in the left pane.

2. Double-click a service to bring up a window with several options. In the Startup Type area, you can set the service to run automatically in the background at all times so it's ready whenever it's needed, or you can tell it to run manually, which means you'll have to go into this Services management console and re-enable it if an application needs it.

You can also completely disable the service. In general, you want to disable services tied to applications and/or features you don't use or rarely use. You can find a great list of appropriate services to disable at the Elder Geek's Services Guide For Windows XP.

If you're logged onto the computer as the administrator, you can also pause the service (click the Pause button in the Service Status area just below the Startup Type area), then see how the computer behaves. Danger signs include crashes or other erratic behaviors in your applications, such as running slowly or getting stuck on a query prompt. Click Resume to start up the service again.

Computer Maintenance Tips

Ten tips to keep your computer running smoothly:

1. Never, never, turn your computer off with the power switch until Windows has shut down.

The one exception to this rule is when your computer locks up and your hard drive is not running (hard drive light is not blinking). In this situation, you can turn the power off without harmful effects to the hard drive. As cutting the power can also result in lost data or Windows files, you should only do this when you have to.

Following this rule will prevent permanent hard drive defects caused by the hard drive heads contacting the surface of the drive disc, and it will prevent a host of Windows problems.
Whenever possible, recover from crashes by pressing the Ctrl + Alt + Delete keys at the same time. Press them again to reboot your computer.

2. I highly recommend that you purchase an UPS (uninteruptable power supply) for your computer. This will keep your computer from crashing during power outages, and will protect your computer from low and high voltage occurrences.
An UPS is far superior to a surge protector and will save your computer from almost any power type of disaster. (See #1 above for what happens when your computer crashes.)

3. Backup, backup, backup, any data you cannot afford to lose to at least two separate physical drives. So backup data to floppies, Zip disks, CD-RWs etc.
The time to backup is when you create something you can't afford to lose. Don't wait until tomorrow.

4. Run Scandisk and Defragment at least once a month. This will keep your hard drive healthy and prevent crashes. Alternatively, purchase Norton Utilities and use it to keep your hard drive healthy.

5. Never unplug peripherals from the computer when it is powered up. Unplugging with the power on can short out the connector socket or the motherboard.

The only exception to this rule is if you know a peripheral is "hot pluggable". If you do not know what "hot pluggable" means then ignore this exception.

6. Do keep at least 100 MBs of your C: drive free for Windows to use. If you use Windows Me or Windows XP then you should have 200 MBs of free space on your C: drive.
If you do not have enough free space you will choke Windows and it will start dumping data to your hard drive, or it will just get really, really, slow.
Use the ADD/Delete tool in the Windows Control Panel to delete unneeded programs from your drive.
You can also use Cleansweep included in Norton Utilities to clean up your drive. If you do use Cleansweep or another hard drive cleaner, do not delete shared files unless you back them up. The cleaners do a rotten job of knowing if another program uses shared files.

7. Do not let a lot of programs load up when you start your computer. They use valuable memory and Windows Resources (Windows internal workspace).
All programs in your Windows System Tray (in the lower left of your screen) are running on your computer. Close them if you don't need them or run them and configure them not to load when you boot up.
Other programs running in the background can be found by pressing Ctrl + Alt + Delete at the same time.

8. Do use a virus checker regularly. Everyone should use a virus checker. The best type of protection is continuous monitoring from a dedicated anti-virus program like Norton Antivirus.
The second best thing is to use is the free online virus checker Housecall provided by Trend Micro.

9. If you have a high speed Internet connection you need a firewall program. A firewall program keeps those who want to hijack your computer from gaining access to your system. You really do not want someone else running your computer.
I suggest you purchase and run Norton's Personal Firewall program. Your firewall should boot up with your computer to protect it from invasion. A free personal firewall program is available from Tiny Software.

Case in point: When I run Windows Me for 10 hours or more with my DSL connection, my computer is usually attacked by a hacker at least once.
Do not think you are safe from hackers!! Hackers use search programs to seek out computers at random. Get a firewall program and use it.

10. Keep track of the software disks you receive with your computer and new peripherals. These disks contain valuable software drivers and programs for Windows and are needed when Windows must be reloaded. Keep these disks and your Windows software disks in a safe, dry, place -- you never know when you will need them.

Virus Protection Tips

Computer viruses are increasingly common and destructive, and IT Services makes every effort to keep Iowa State University and supported computers free from infection. To help reduce the risk of infecting your computer and the computers of others please follow these virus protection tips from McAfee and IT Services.

1. Do not open any files attached to an email from an unknown, suspicious, or untrustworthy source.
2. Do not open any files attached to an email unless you know what it is, even if it appears to come from a dear friend or someone you know. Some viruses can replicate themselves and spread through email. Better be safe than sorry and confirm that they really sent it.
3. Do not open any files attached to an email if the subject line is questionable or unexpected. If the need to do so is there always save the file to your hard drive before doing so.
4. Delete chain emails and junk email. Do not forward or reply to any of them. These types of email are considered spam, which is unsolicited, intrusive mail that clogs up the network.
5. Do not download any files from an unknown, suspicious, or untrustworthy source.
6. Exercise caution when downloading files from the Internet. Ensure that the source is a legitimate and reputable one. Verify that an anti-virus program checks the files on the download site. If you're uncertain, don't download the file at all or download the file to a floppy and test it with your own anti-virus software.
7. Update your virus definitions regularly. Over 500 viruses are discovered each month. While your virus protection software is scheduled to update your virus definitions automatically, occasionally you may need or want to update your virus definitions manually.
8. When in doubt, always err on the side of caution and do not open, download, or execute any files or email attachments.
