Sometimes it can be very useful to access Linux Extended File System using Windows to copy important data or just check out its contents. The best way to do this is to use Ext2Fsd an Extended File System driver for Windows.
Ext2Fsd is an Extended File System driver for Windows 2000, Windows XP, Windows Vista and Windows 7. It supports reading from and writing to Second Extended File System (ext2) and Third Extended File System (ext3), reading from Fourth Extended File System (ext4).
I am using it extensively to access my portable external hard drive on other computers without any problems.
