I have read articles that suggests using registry cleaners to restore a system’s performance. However, I have also read a article in a Windows XP forum that says cleaning the registry will essentially degrade system’s performance rather than restoring it. How true is this? Dedicated for IT experts.

I have a HP Pavillion DV8000T notebook that i purchased from HP directly. The notebook is 13 months old and out of warranty. My hard drive failed and I will need to have it replaced. This is the second time my hard drive has failed (previous instance was during the warranty period) My options are:
(1) Use HP and pay 0 – this includes a new hard drive and installation of MS Windows XP Media edition. It comes with only 90 day warranty.
(2) Buy the hard drive myself – I have Windows XP software. I would have my office IT desk install the hard drive and the Operating System. Cost 0.
My Concern is:Will I be able to get all the drivers that I need to get the most of my machine. This is a high end machine but I am extremely disappointed with HP service. There is only a 90 day warranty on a 0 repair which represents over 33% of what I paid for the entire machine. Since the hard drive has failed twice already-I figure if it fails again, I will buy new notebook.

I am using Registry Mechanic 6.0.Lately, it has not repaired all the errors. For example, I will scan. It finds 3 errors. I delete them and then run the scan again. It finds the exact 3 errors again. After running this 3 times, I am wondering if I need to change registry cleaners or just go without. Is it absolutely necessary to have a registry cleaner if I’m using Windows XP sp2 and do the maintenance on a routine basis?

I’ve noticed little things and small errors popping up like invalid so and so. So, my question is, is there a good free program to clean out the Windows registry you guys can recommend for Windows XP SP2?

I have Windows XP and I’m concerned that a Registry Cleaner will erase important stuff. Also, are you familiar with "AML Free Reguistry Cleaner"? Thanks.
