What should I do if the Win7 camera fails to open and the message is incorrect (code 19)?

Xiaobian Win7 books on the camera is rarely used, today's whim to open it but failed, open the device manager to view, also prompted: registry information error (code 19). Let's analyze the causes and solutions together.

Cause analysis:
Because the third-party software takes over the system driver library, the component information in the system registry information is added with the key value of a third-party software, which causes the device to be self-identified and driven. Obstruction, so the driver cannot be loaded properly and cause a malfunction.
Solution:
First, please click back to the desktop, press the win+R key combination to open the “Run” window, enter “ldedit” in the run window, press Enter to open the system registry. As shown below:

Please find HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Class\\{6BDD1FC6-810F-11D0-BEC7-08002BE2092F} through the tree structure on the left. After the subkey finds the key value, Please delete the Upperfilters value and the Lowerfilters value in the right window (if you don't have this key value, don't modify it temporarily, delete it if you don't have it), restart the computer, and then uninstall and reinstall the driver.

With the above method, we can basically solve the problem that the camera can not be opened. If friends and friends are in the process of operation, what problems occur, welcome to interact with Xiaobian messages.
