Glary Utilities is free and I been using it for a few months to delete unwanted junk files, remove unwanted registry keys, remove useless shortcuts, remove spyware/malware, and protect your privacy with one click of the mouse . I also like the Registry defragmentation tool. The Duplicate file finder, and Memory Optimizer is also very useful. It also help me clean up my right click menu. It is a great all in one maintenance program. There are many more features built into Glaries that will take too long for me to explain. It is free, and you have nothing to lose.
A dual boot computer is a computer that can boot from one of  two operating systems installed on a computers Hard drive.
I will teach you how to make a dual boot operating system computer that can boot from Windows XP, or Ubuntu 9.04 on the same computer.Â
What you need : a computer with 1-2 hardrives with atleast 14GB of free space. 1.2GHz processor, 384MB RAM
If you already have Windows installed on your computer, you can either install a second hard drive or re size your Windows Partition/hard drive space with Parted Magic . Back up your important files before partitioning your hard drive, or you can clone your Windows drive with Clonezilla.Â
