How to Disable Write Access to USB Removable Storage Devices

Here’s how to disable (and re-enable) write access to removable storage devices such as USB pen sticks and portable hard drives:

Editing the Registry Yourself

 

it’s pretty easy and only involves creating and editing a single key value.

1. Go to Start -> Run -> Type regedit and hit Enter or click on the OK button. For Vista and 7 go to Start -> type regedit into the search box, hold Ctrl+Shift and press Enter. Ctrl+Shift opens regedit as Administrator.

2. Browse to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control

Look for a key in Control called StorageDevicePolicies. If you have a key with that name go to step 4. If not, follow step 3.

3. You need to create a new key called StorageDevicePolicies. Right click on Control, select New -> Key and type in StorageDevicePolicies. Make sure not to include any spaces before or after.

4. Right click on the StorageDevicePolicies key and select New -> DWORD Value, or DWORD (32-bit) Value for 64-bit operating systems, and call it WriteProtect. Double click on WriteProtect and set the value from 0 to 1.

This will prevent users from writing to USB drives with the message “The media is write protected”.

The procedure to allow writing again to USB storage devices is simply setting the Write Protect value back to 0. To avoid any potential issues it’s best to perform this procedure while you don’t have a USB storage device plugged in. Although I simply unplugged my USB stick and reinserted it for the registry change to take effect, it might avoid any other problems that might occur.
The good thing about this is you don’t need to restart, I’ve been able to test this method several times without rebooting either XP or Windows 7 once. This is confirmed to work perfectly fine on Windows 7 32-bit and 64-bit.

How to Add Any Application to the Windows Desktop Right-Click Menu

If you want really quick access to launch a frequently used application without putting extra icons on your desktop, you can add that application to the context menu for the desktop with a simple registry hack. Here’s how to do it.
Naturally, we’ve also covered the opposite scenario—how to disable Windows context menu, which is an equally useful read if you’ve got a bunch of items you want to remove from the menu.

Adding Applications to the Desktop Context Menu

For today’s lesson we’ll show you how to add Notepad to the menu, but you could add any applications you want instead. The first thing you’ll want to do is open up regedit.exe through the Start Menu search or run box, and then browse down to the following key:

HKEY_CLASSES_ROOT\Directory\Background\shell

The screen should look similar to this one if you are in the right place.
Next, you’ll want to create a new key underneath the shell key, the name of which is exactly what is going to show up on the desktop menu. Right-click on the “shell” key, and then choose New \ Key from the menu.

Give the new key the name that you want to show up on the desktop context menu. For this example we’ll be using Notepad.

 Optional: If you want to assign an “Alt” key to this menu entry for quicker access, you can change the (Default) value on the right and put an & character in front of the key you want to use. For instance, if you wanted to be able to just use the N key to launch Notepad once the desktop context menu pops up, you can do this:

Personally I don’t find this terribly useful since you have to use the mouse to right-click on the desktop… may as well just use the mouse to click the item. Still, for completeness I’ve included it.
Next you’ll need to create the command key that will actually hold the command used to launch the application. Right-click on the new Notepad key, and then choose New \ Key from the menu.

 

 Give this key the name “command” in lowercase.

 To complete this step you’ll need the full path to the application that you want to launch. You can use Shift + Right-Click to get the Copy as Path menu item to find this more quickly. Note: of course, for Notepad you wouldn’t need the full path, but this is just an example.

 Now click on “command” on the left side, and then double-click on the (Default) key in the right side to edit the string value.

Paste in the full path to the executable that you got from the “Copy as Path” step above, or you can put in the full path yourself if you’d like.
Once it’s done, it should look like this:

 And right-clicking on the desktop will produce the new menu item… naturally, using this menu item should launch Notepad.

 You can add as many applications to the desktop context menu as you’d like, just repeat the steps again with a new menu item name.
