Please help in getting rid of the errors noticed in the Windows Vista Registry Cleaners. I want to know how I can successfully back up the existent registry. When I executed the work, I encountered a lot of problems. Some of the data disappeared. I heard that a demo version is available that can help me understand the functions offered in this cleaner. If I can get my hands on the same, I am sure that I will be able to fix all the problems. But, I couldnít find the trial or demo version. Thus, Iím here to seek your advice.
