What's the best way to back up and--just as important--restore the Windows Registry?

Author: Hubert Harriman, Miami

Windows 98, Me, and XP back up the Registry automatically at regular intervals, but it's still safest to back up your Registry manually before you make any major changes to your system. These are the best ways to back up and restore the Registry in various versions of Windows.

Windows 98: Select Start, Run, then type scanreg and press Enter. When you're told that there are no errors, click Yes to back up the Registry, then OK. To restore the Registry, select Start, Shut Down, click Restart in MS-DOS mode, and click OK. At the C:\WINDOWS> prompt, type scanreg /restore (don't forget to put a space before the slash) and press Enter. Select a backup from the list and press Enter again.

Windows 2000: There's no good method to back up the Registry in this OS. Some people use Regedit's Export feature, but in my experience this isn't a reliable way to back up the entire Registry (although it works quite well if you're backing up only parts of it). For backing up and restoring the Registry in Windows 2000, I recommend Super Win Software's $25 WinRescue 2000. Go to Superwin.com/rescue to download a trial version.


Old-Fashioned Alt-Tab

In previous versions of Windows, I could quickly Alt-Tab between open programs. But Windows XP shows each open program in a kind of preview mode, slowing the whole process down. Is there a way to turn off this preview mode? Me and XP: Select Start, Programs (All Programs in XP), Accessories, System Tools, System Restore to bring up the System Restore Wizard. To back up your Registry, choose Create a restore point; to restore the Registry, select Restore my computer to an earlier time.

That overly graphical version of the Alt-Tab pop-up is actually not part of Windows XP, but of Microsoft's PowerToys for Windows XP. This free collection of utilities has several useful tools, including the oft-recommended Tweak UI. The PowerToy that's slowing you down is called Alt-Tab Replacement. FIGURE 1 shows both the old Alt-Tab window and the PowerToy version.

It's not surprising that you mistook this optional add-on for a part of Windows. Accidentally installing more PowerToys than you want is quite easy. Some systems even have PowerToys preinstalled. What's more, the Alt-Tab Replacement tool doesn't show up on the Start menu with the rest of the PowerToys.

To get rid of it, select Start, Control Panel, then double-click Add or Remove Programs. On the list of currently active programs, choose Powertoys for Windows XP and click Change. In the resulting wizard, click Next, select Modify, and click Next again. Choose the icon to the left of Alt-Tab Replacement and select This feature will not be available. Click Next, Install, Finish, and reboot Windows

Return of the Arrows

I used Tweak UI to turn off the arrows on shortcut icons, but after I loaded a Windows Security Update and Internet Explorer 6, the arrows returned. Tweak UI thinks they're gone. What can I do?

Many Windows 98 users had shortcut arrows come back after they installed a security update. Tweak UI considers the arrows off, and setting the program to turn them on, then off again, won't work.

Freshdevices' free Fresh UI utility will do the trick. Point your browser to www.freshdevices.com to download your copy. Inside Fresh UI's left pane, navigate to Windows Interface, Desktop, Shortcuts, Shortcut Arrow. Next, in the right pane, double-click the Show arrow on shortcuts option. Uncheck the three options it gives you, and then click OK.

Easy Network Backups

Ed Anderson of Syosset, New York, suggests a fast and easy way to back up multiple PCs that are networked together (for instance, via an Internet-sharing router): Simply back them up to each other. It's faster than backing them up to CD-RW or other removable media, and if the PCs all have enough extra space on their hard drives, it's cheaper as well. Should the hard drive on one system fail, your data is safe on the other computer. Anderson uses Iomega's QuikSync for his backups, but the same technique should work with most backup programs.
