How to Use System Restore
System
Restore regularly captures system settings so that you can restore them
later if you experience a problem. Using System Restore to return your
computer to an earlier state should be one of your last troubleshooting
steps, however, because it might cause problems with recently installed
applications and hardware.
You can run
System Restore from within either the System Recovery tools or from
within Windows Vista. To use System Restore from System Recovery tools
(which is only necessary if Windows Vista will not start). To use System Restore from within Windows Vista, follow these steps:
1. | Click Start, click All Programs, click Accessories, click System Tools, and then click System Restore.
|
2. | The
System Restore Wizard appears. If this is the first time you are
running the System Restore Wizard, click Next to accept the default
restore point.
|
3. | If
you have run System Restore previously and it did not solve the
problem, click Choose A Different Restore Point, and then click Next.
|
4. | On
the Choose A Restore Point page, select the most recent restore point
when the computer was functioning correctly. Click Next.
|
5. | On the Confirm Your Restore Point page, click Finish. When prompted, click Yes.
|
6. | System
Restore restarts your computer. When the restart has completed, System
Restore displays a dialog to confirm that the restoration was
successful. Click Close.
|
If System Restore does not solve your problem, you can do one of two things:
Undo the System Restore
The problem might not be the result of changes to your computer at all,
but rather a hardware failure. Therefore, using System Restore might
not solve your
problem. Because restoring the computer to an earlier state might
remove important changes to your system configuration, you should undo
any restorations that do not solve your problem. To undo a System
Restore, simply re-run System Restore using the steps in this section,
and choose the default settings.
Restore an earlier restore point
Your problem may be caused by recent changes to your computer, but the
negative changes occurred before the most recent System Restore.
Therefore, restoring an earlier restore point might solve your problem.
Repeat the steps in this section to restore to an earlier restore point.
How to Troubleshoot Bluetooth Problems
Bluetooth
is a wireless protocol for connecting accessories to computers.
Bluetooth is commonly used to connect keyboards, mouses, handheld
devices, mobile phones, and GPS receivers.
Bluetooth
is simple enough to configure that most users can connect Bluetooth
devices without help from the support center. However, users may
occasionally have problems initiating a Bluetooth connection. Other
times, a connection that previously worked may stop working for no
apparent reason.
If you cannot successfully connect a Bluetooth device, try these troubleshooting steps:
1. | Verify that the device is turned on and that the batteries are charged.
|
2. | Place
the device within a few feet of your computer (but not too close to
your Bluetooth adapter). Additionally, verify that the device is not
near other devices that use radio frequencies, such as microwave ovens,
cordless phones, remote controls, or 802.11 wireless networks.
|
3. | Verify
that the device has Bluetooth enabled and that it is configured as
discoverable. For security reasons, many devices are not discoverable
by default. For more information, refer to the instructions that came
with the device.
|
4. | Install any updates available from Windows Update.
|
5. | Download
and install updated software and drivers for your hardware. Hardware
manufacturers often release updated software for hardware components
after they release the hardware. You can typically download software
updates from the manufacturer’s website.
|
6. | Verify that Windows is configured to accept incoming Bluetooth connections.
|
7. | Verify
that security is configured correctly. You might have configured a
non-default passkey for your device. By default, many devices use 0000
or 0001 as a passkey.
|
8. | Remove and reinstall the Bluetooth device.
