Hiee Everyone!!!I just found thing in Windows Registry service..It is quite interesting and strange.I verified that one can Disable USB ports on Windows PC via Registry.Yes it is true and it is working..
Most of us does not allow others to work with our own PC.And it gives some disturbance to us.Using other USB(Universal Serial Bus)drives in our PC is not acceptable at all time..
With this trick, you can disable access to your USB (Universal Serial Bus) ports on your Windows based PC to prevent people from taking out data without permission or spreading viruses through the use of USB (pen and flash) drives.
To use this trick to disable USB ports, follow the steps given below:
1. Click on Start.
2. Click on Run. If you cannot find RUN, type it in the search box.
3. Type "regedit" without quotes. This will launch the Registry Editor.
4. Now Navigate to
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\usbstor".
5. In the work area, double click on Start
6. In the Value Data box, enter 4.
7. Click on OK.
8. Now Close Registry Editor and refresh your desktop.
Finally you Disable ports on Windows.This means no one can access your ports without your permission and rights.
9. To re-enable access to your USB ports, enter 3 in the Value Data box in Step 6.
Try it yourself to make your PC invulnerable from data theft and malware which spread through USB ports.
This works on Windows XP, Windows Vista, Windows 7 and Windows 8.
