Vista Sp1 Problem

Hi All, Vista Home Premium. Using Windows Update I installed SP1.It caused major problems.Iused System Restore annd got everything back to normal except
my DVD-RW .It is not recognised in Windows.In Device Manager it shows that there is a problem,stating that Windows cannot start this hardware device because
its configuration information (In the Registry) is incomplete or damaged.(CODE 19).
Pioneer DVD-RW DVR 109 ATA.
Any help will be appreciated Regards JOCKCON

Have a look here; http://tinyurl.com/4zx6y3 .Be careful when editing the registry. If you try SP1 again and have problems you can uninstall it via controll panel; http://www.pctipsbox.com/uninstall-w...ervice-pack-1/ .
