Windows Easy Transfer
Windows Easy Transfer (WET) is a nice tool for migrating from one computer to another one. It does not transfer installed applications, but it transfer their settings and user documents. For example, IE will have all the favorites, short cuts and other settings on the target computer with WET. This can save a lot of time.
It has three methods of transferring: an Easy Transfer cable, a network and an external hard disk. The first needs to be purchased, so it is not a good choice if one only needs to run WET once in a while.The second one is handy if it works. I have tried to use it many times under different circumstances, and it never worked. The 3rd one is the most robust option.
WET does not handle user folder redirection well. For example, one may use a small SSD to store the OS and all the programs, and redirect use data folders to a hard drive. WET does not transfer such redirection, so it is very important to set up folder directions before using WET.
