Bluetooth is a radio technology that supports short-range communication between devices. Bluetooth is now widely used on mobile phones and computers. If the Win7 system computer does not have a Bluetooth driver installed, it needs to be installed before it can be used. Recently, some users found that the installation failed when installing the Bluetooth driver. How to do? How to solve such a problem? Now let me talk about the reasons and solutions for the failure of Win7 Bluetooth driver installation.
The steps are as follows:
First, the cause analysis:
The optimization software deletes the files in the system INF folder by mistake.
Second, the solution:
1, enter the \\Windows\\inf directory of the C drive system partition, check whether there is a "bth.inf"; file, note: if in the C drive -- Windows--inf--“bth.inf” only shows bth, no .inf suffix can be found, click “tool——folder option——view——cancel checkmark<quo;hide Know the extension of the file type ”——determine”.
2. If you still don't have one, find C drive ——Windows——System32——DriverStore——FileRepository—Find and open the folder at the beginning of “bth.Inf” (for example: bth.Inf_amd64_neutral_ale8f56d586ec10b), confirm whether there is a bth.Inf file, copy the “bth.Inf” file to the C:\\Windows\\inf directory.
3, right click on the computer icon to select "Administration - Device Manager", uninstall the unknown device of the yellow exclamation mark, reinstall the Bluetooth driver.
