How to write protect a USB key?

I have a pen drive which I used to carry some files from my laptop to other public computers, and these public computers are virus infected. Now I want to make my pen drive write protected so that these viruses can't infect my pen drive.

What are the solutions?

Buy a new USB drive with a write protect switch.

Short of this, there isn't any guaranteed way.

You would need to be able to edit the registry on the system you're inserting your USB drive into.

Add (DWORD) or modify existing key at

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies\WriteProtect

and set to 000001 to disable writing, 000000 to enable writing.
