Modify the registry to solve the abnormal situation of the CD-ROM reading disk

The status of the CD-ROM drive is a bit embarrassing now, now everyone's software or video is downloaded or viewed online, and rarely use the CD-ROM to complete, but if at work If there is still a need, the problem of CD-ROM reading will be solved in time. I don’t know if it has the following conditions? Some friends’ computers are installed with Windows XP operating system. After installation, there is a problem. Can not read the disc continuously, insert the first disc is normal, open the CD-ROM and put the second disc, and find that the content inside is actually the content of the first disc. After restarting the machine, the second disc can be read normally. What is the reason?

Solution: Right click on “My Computer", select “Manage”, select “save →removable storage →library" In the name of the drive letter, right click on the name item and select “Attributes”, and under “Delay Unloading”, there is one item that is “Recovered” Load media & rdquo ;, it's time to 0, should be able to solve this problem. If the problem is not resolved, open the registry editor, find the HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E965-E325-11CE-BFC1-08002BE10318} key value, delete the UpperFilters and LowerFilters below, and restart the machine.

The optical drive is not normal. In general, it is not a big problem. Just modify the registry to do it, but because it involves the modification of the registry, remember to back up the registry before modifying. Nothing is wrong.
