I am new to the forum. I have windows xp and I had norton systemworks with one button check-up with built-in register cleaner, I have now changed to another system but it has not got a register cleaner. can you tell me if it is good to download a free register cleaner and which one Please would you recommend and how do you use it?
Thank-you

RegSeeker works well and is fairly self-explanatory:

As to a main back-up and optimizer this is a good free app:
