This is the definit tweaking program. There are so many tweaks you can make its like having a registry bible explained in child's language. The administrator options are incredible. There is also total support from the online help. Just get all the other tweaking programs and throw them away. This is clearly programmed in C as the file is so small for all the functions it incorporates. Windows-help.net know what they are doing. The best tweaker around for miles and miles. I highly recommend it.
