Hi all,
I just installed xp yesterday in my pc. version 2002 sp3. but unfortunately there is no address bar in any window. This is an Inconvenience for me. so plz help me to find the address bar. And i installed xp in my drive "C". Total space in C is 24.4 GB. All my installed programmes and windows files are showing a size of 3.7GB. So there should be a free space of 20.7 GB. But my pc shows only 18.5 GB free space in C. I can't see any files or folders which contains 2.2 GB. There is no hidden files in C. So plz help me to find these 2.2 GB.
