Your office uses Windows Vista. This morning, a patch was applied automatically. Suddenly, the
users who have scanners attached to their computers complain that they cannot access the
scanners. When you check their Device Manager, you notice there is no exclamation point next to
the scanner. What should you do now?
A.
Reinstall Vista.
B.
Find a Vista compatible scanner.
C.
Manually uninstall and reinstall the device driver.
D.
Roll back the patch.
Explanation:
Sometimes a patch may cause problems for an existing device driver. Usually, you simply uninstall
and then reinstall the driver. This way the driver is installed after the patch.
Answer option D is incorrect. Patches often have key security updates. Simply leaving the machine
unpatched is never a good idea.
Answer option A is incorrect. This drastic step will return you to the pre-patch state, but then you
will still need to apply that patch, and still have to deal with this problem.
Answer option B is incorrect. The scanner worked with Vista before the patch. This indicates that it is
Vista compatible.
