Say goodbye to unwanted intrusions and data leaks! 🚫🔑 In today's digital world, security is a major concern for individuals and businesses. One of the most common vectors for these threats is the use of USB drives, which can easily transmit malware or steal sensitive information. But don't worry, we have the solution for you! 💡 it is possible to secure your Windows by blocking the use of USB keys .
Here is a video tutorial to save time using method 3 in our article!
The risks associated with using USB keys
Before we dive in, it is crucial to understand why it is necessary to block the use of USB drives. Removable storage devices present several risks:
- Spread of malware
- Theft of sensitive data
- Accidental loss or corruption of files
By blocking access to USB drives, you significantly reduce these threats and effectively protect your computer. During your research, have you already come across this article from Microsoft ? Didn't you understand anything? Follow these simple and effective methods to successfully complete the operation.
Method 1: Use Local Security Policy Editor
One of the methods to block the use of USB drives in Windows is to use Local Security Policy Editor. Here are the steps to follow:
Step 1: Press Windows + R to open the Run dialog box.
Step 2: Type secpol.msc and press Enter to open Local Security Policy Editor.
Step 3: In the left column, navigate to Local Security Policies > Local Policies > User Rights Assignment.
Step 4: Double-click “ Deny access to removable drives ” in the right pane.
If you cannot find the “Deny access to removable drives” option in Local Security Policy Editor, it could be due to the version of Windows you are using. Some versions of Windows , in particular the “Home” or “Family” editions, do not offer this option. In this case, you can try using Local Group Policy Editor (gpedit.msc) or edit the Windows registry to block access to USB drives. We invite you to see the methods below!
Step 5: Select “Set this security policy” and add the relevant user accounts.
Step 6: Apply the changes and close Local Security Policy Editor.
After performing these steps, affected users will no longer be able to access USB drives on the computer.
