What if the Win7 disc does not play automatically?

Although there are a lot of video resources on the Internet, there are still many people using CDs, especially some teaching CDs. When a friend puts the CD into the CD-ROM drive, it is found that the CD cannot be played automatically, but it can be played manually, which is very inconvenient to use. So how can I solve the problem that Win7 CD can't be played automatically?

There are many reasons why the CD-ROM can't play the CD, but it's nothing more than the following:

1. Anti-virus Blocking software and computer security software. Since many CD viruses and U disk viruses are now transmitted through automatic playback, some anti-virus software and computer security software have prevented the CD from playing automatically because of the need for computer security protection.

2. The operating system itself limits. In particular, the operating system of win7 and later is also a computer security consideration and the automatic playback function of the computer optical drive or USB flash drive is disabled by default.

3, the computer user's security configuration of the operating system (such as prohibiting the automatic playback of the CD through group policy, prohibiting the automatic playback of the CD through the registry, etc.), can also prevent the automatic operation of the CD or U disk; >

4, optical drive or U disk itself, such as optical drive failure and other reasons;

Therefore, to solve the problem that the CD can not automatically play should start from the above aspects, in the possibility of eliminating the device itself failure After that, the problem that the disc cannot be automatically played can be solved from the following aspects. Of course, it is forbidden to perform the reverse operation only if the disc is not automatically played and the autoplay disc is not set.
