Password protected zip file in Windows 7

In Windows XP, we can right click the zip file and select explorer->File and enter password for zip file. But there is no such feature in Windows 7.

One solution is to use peazip.  peazip is a free Zip utility, extract RAR TAR ZIP files,
compress, convert, split and encrypt archives,150+ archive formats supported. peazip can be download from:
http://peazip.sourceforge.net/

After install peazip, start peazip,
click Tools at the top menu, select "enter password/keyfile"  and enter password.
Select the files  in the content and click add, a new window will show. Click OK to zip the files.
And this zip file is password protected.
