EFS - Encrypt Content not really encrypting??

I am starting to keep my files encrypted, but the files are readable from any
PC. I wonder if I am doing something wrong or have an error of understanding.

Activate Encryption in Vista Ultimate:
- I go to Explorer
- Right-click on a file -> Properties
- General -> Advanced -> and activate "Encrypt Contents to secure data"
- File now shows in green color

This is how I tested it:
Test 1: Winzip the File. Copy it to another Windows XP PC
Test 2: WinSCP the file to a Linux File Server, copy it from there to
another Windows XP PC

In both cases I can read the file on the other PC. What did I miss?

You're reading the file from disk, during which process the file is
decrypted, you're then storing it in the zip format which creates a new,
unencrypted file.

Again, you're reading the file from disk which decrypts the file, you're
then copying the decrypted bits over the network, again creating a news,
unencrypted file.
