RESTORING AND BACKING UP WINDOWS 98 REGISTRY

Backing up the Windows 98 Registry

Windows 98 introduced a new utility known as Scanreg, which automatically makes backups of your Registry each time you boot up your computer.

Tip: The steps listed below for backing up Windows 95 Registry also work but are not necessarily needed unless you wish to keep an original elsewhere.

Restoring Windows 98 Registry

To restore Windows 98 Registry, open a MS-DOS prompt.

At the MS-DOS prompt, type cd\windows\command

Once in this directory, type scanreg /restore this will restore an earlier version of your Registry. Once completed, reboot the computer and this should resolve any issues that may have occurred with your Registry.

If you backed up your Registry using the Windows 95 steps use the Windows 95 restore steps to restore the Registry.

BACKING UP THE WINDOWS 2000 REGISTRY

The Microsoft Windows 2000 Registry can be backed up from the backup utility by following the below steps.

1. Click Start, Programs, Accessories, and click backup.
2. Within backup, click the backup tab.
3. Within the backup tab, check "System State", this will create a backup of boot files, COM+ Class Registry Database, and the system Registry.

Restoring the Windows 2000 Registry

If you have created backups using the Microsoft backup utility from the backup utility you can also restore the Registry through this utility.

RESTORING THE WINDOWS 7, VISTA AND XP REGISTRY

To restore the system back to an earlier point follow the below steps.

1. Click Start, Programs, Accessories, System Tools, System Restore
2. Select the Restore my computer to an earlier time option (as shown in the below picture) and click Next
3. Select the day and the restore point you wish to restore and click Next.

HOW TO USE SYSTEM RESTORE IN WINDOWS XP

No matter the cause, you can follow these steps to use System Restore in Windows XP:

1. Save everything.
   Save all files and close all open programs before System Restore restarts your computer.
2. From the Start button menu, choose All Programs→Accessories→System Tools→System Restore.
   The main System Restore window is displayed.
3. Choose the option Restore My Computer to an Earlier Time.
4. Click the Next button.
5. Choose a restore point from the cute calendar-like thing.
   The most recent date is chosen by default use it unless you already tried it and experienced problems.
6. Click the Next button.
7. Read the warning.
   The text warning is in Red. However, you are, good to go.
8. Click the Next button.
   It should be named Finish because it’s the last step: System Restore restarts Windows XP.

After you log in again, you need to wait a bit more. Eventually, you see a confirmation message explaining that Windows has been restored. You see a window that details what happened; click OK to close the window.
Restoring the system is also a start-up option. Choose the option Last Known Good Configuration, which is more or less the last system restore point.

You can also perform System Restore in Safe mode. That’s a good choice, especially when the computer is unusable otherwise.

TROUBLESHOOTING MOUSE IN WINDOWS 8

Sometimes, the mouse doesn't work at all; other times, the mouse pointer hops across the screen like a flea. Here are a few fixes to try:

• If no mouse arrow is on the screen after you start Windows, make sure that the mouse's tail is plugged snugly into the computer's USB port. (If you have an older mouse with a round PS/2 port instead of a rectangular USB port, you need to restart your PC to bring the newly plugged-in mouse back to life.)
  
  
•  To restart your PC when the mouse doesn't work, press these keys from either the Start screen or the desktop: Press the Windows key and I key simultaneously to fetch the Charms bar's Settings menu. Then press your keyboard’s arrow keys to highlight the Power button near the bottom of the Settings pane. Press Enter to fetch the Power menu, then tap your Up Arrow key to highlight Restart. Press the Enter key to restart your computer.
  
  
• If you own a cordless mouse, the little guy probably needs new batteries.
  
  
• A mouse pointer can jump around onscreen erratically when the mouse's innards become dirty. Clean the mouse's under parts with a moist rag, making sure to remove any debris.
  
  
• If the mouse was working fine but the buttons seem to be reversed, you've probably changed the right- or left-handed button configuration setting in the Control Panel. Open the desktop Control Panel's Mouse settings area and take a look at the setting for Switch Primary and Secondary Buttons. Lefties want it turned on; righties don't.
