How to disable USB flash drives on the company's computer, prohibit USB flash drives from copying computer files on the company's computer, and prohibit USB flash drives on the computer
At present, USB flash drives are frequently used, and the read/write speed and storage space are getting bigger and bigger. Although it is convenient to work, it also makes it extremely convenient to copy computer files through USB flash drives, in particular, when a company computer stores a large number of files, it can easily copy computer files through a USB flash drive and then carry them out. So, how does a company's computer prevent data leaks, how does it prohibit the use of USB flash drives, and prevent the copying of computer files through USB flash drives? I believe that the following two methods can be used to disable USB storage devices and prohibit copying computer files through a USB flash disk. The details are as follows:

Method 1: Use a dedicated USB port management software to prohibit USB flash drives from copying computer files, disabling USB storage devices, and copying computer files to USB flash drives.

At present, there are many effective computer U port management software in China, which can effectively prohibit the use of USB flash drives, restrict Blue Teeth, disable mobile phone memory cards and other devices with USB storage functions. For example, there is a "portable to USB port control software" (: http://www.grabsun.com/monitorusb.html), you can easily achieve the function of prohibiting the use of U disk, of course, you can also only copy files from a USB flash disk to a computer instead of copying files from a computer to a USB flash disk, or enter a password when copying files from a computer to a USB flash disk. In this way, those who use your computer cannot be copied because they do not have a password, which can protect computer file security and trade secrets. As shown in:

 
Figure: USB control software
In addition, you can use the portable to disable USB flash drive software to prohibit sending email attachments, uploading computer files to network disks, uploading FTP files, sending files via QQ, and uploading attachments to forums, in this way, the security of computer files and the intangible assets and trade secrets of the organization are fully protected.
Method 2: Disable USB flash drives or block USB storage devices by using a group policy in the Registry to prohibit copying computer files to protect the security of computer files.
1. Click the windows button in the lower-left corner of the screen and enter "gpedit. msc and press the Enter key to confirm that the "Local Group Policy Editor" window is displayed, as shown in:

 
2. Expand "Computer Configuration"> "management module"> "system"> "Removable Storage Access" in the "Local Group Policy Editor" window ", find "all removable storage classes: deny all Permissions", as shown in:

 
3. Double-click the "all removable storage classes: deny all Permissions" option, select "enabled" in the pop-up window, and then click "OK", as shown in:

 
After performing the preceding operations, you must restart your computer to make the settings take effect. Therefore, remember to restart your computer!
Prohibit other USB flash drives from copying data from your computer, and prohibit your computer from copying data from the USB flash drive. Therefore, please be careful!
The following is a detailed tutorial to supplement the above method
The first thing we need to do is to open registration, select the Start menu, and then select the running option ,:

 
In the open running option dialog window, enter the Registry command, regedit ,:

 
After entering the Registry command, click OK to open the Registry Editor ,:

 
We open the following path of the Registry in sequence, HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control ,:

 
Right-click the Control key, select new, and select an item ,:

 
Rename the new item and change the name to StorageDevicePolicies ,:

 
Select the StorageDevicePolicies item, right-click a New Dword value, and change the name of this Dword Value to WriteProtect ,:

 

 
Then, right-click the StorageDevicePolicies item and choose export from the shortcut menu ,:

 
After selecting export, the export Registry File window pops up. We put the export file to the root directory of drive C, so we need to browse to the root directory of drive C and name the exported file "yes. reg ,:

 
Then, select the WriteProtect value on the right of the StorageDevicePolicies item, double-click it, and set the value of the Dword to 1. Here, 1 indicates the meaning of the prohibition. :

 
Change the value to 1 and click OK to close the window. Then, right-click the StorageDevicePolicies item and choose export option ,:

 
Select export, browse to the C root directory, and store the file in the C root directory. You can set the location by yourself. For convenience, I will put it under the C directory and name it forbidden. reg ,:

 
Open the Start menu, select a program, select an attachment, and finally select the notepad file. In the opened notepad file window, enter the Echo off Reg import c: \ yes. reg: Command:

 
Save the file to the path C: \ WINDOWS \ system32 and get the file named. bat. For convenience, I will name it yes. bat. You can name it by yourself ,:

 
After completing the above steps, we will insert the USB flash drive into the computer and copy a file to the USB flash drive to see what will happen ,:

 
It is obvious that there is an effect. Obviously, the file is not copied. How can we copy the file, the first thing to do is to delete the USB flash drive from the computer.
Open the Start menu, select the run option, and enter the name of the batch that you just saved. Here I save it as yes. bat, So I enter yes. bat ,:

 
At this time, re-insert your USB flash drive and check whether the file can be copied again. If you want to disable the copy again, you only need to double-click the ban saved in the C root directory. reg file, re-import registration.
In short, whether the use of USB storage devices is disabled through the registry of the operating system or the use of USB storage tools through group policies, you can also disable the software by using a dedicated USB interface on your computer or by disabling the software on your USB storage device, however, disabling software through a dedicated computer USB interface can not only disable the use of USB storage devices, but also prevent network leaks and achieve more comprehensive computer USB interface management. Although USB flash drives can be disabled through the registry and group policies of the operating system, USB interfaces can be easily re-enabled by employees who modify them in reverse order, at the same time, it is difficult for the operating system to prevent computer files from being leaked over the network.
