მეც ძალიან დიდი ხანია ვიყენებ ორივეს, WinXp-ის ისეთი ღაცაცეები აქ რაც TuneUp-ს არ აქ და პირიქით =)

The problemSome uninstallers for Windows software do not completely remove all traces of the software from the registry. It is possible that these traces may interfere with performance or have other negative impacts. Using a registry cleaner is a way to get rid of these bits. The registry cleaner scans the registry, and picks out the unnecessary and/or damaged pieces and deletes/repairs them.
AdvantagesRegistry cleaners, or registry cleanup software, can in some cases improve the performance of computers by ridding the registry of redundant information.
Due to the sheer size of the registry database, manually cleaning up debris and invalid entries would be impractical, so registry cleaners are essentially tools that automate the process of looking for invalid entries or broken links within the registry and removing them.
Some registry cleaners offer backup and restore functions that allow the user to revert changes made by the registry cleaner in case they are undesired.
DisadvantagesThere are a number of problems with the concept of a registry cleaner. Most notably, there is no reliable way for a program to know whether any particular key is 'junk' or not. Windows is closed source, so registry cleaner designers can not know for sure whether any particular key is still being used by Windows or what detrimental effects removing it may have; leading to examples of registry cleaners causing loss of functionality and, potentially, system instability.[1]
With regards to performance, whilst on Windows 9x computers, it is possible that a very large registry could slow down the computer's startup time; memory management and on-disc structure of the registry is entirely different on the NT line of Operating Systems (including Windows XP and Vista).[2] Slowdown due to registry bloat is thus far less of an issue in modern versions of Windows.
More importantly, however, the difference in speed due to the use of a registry cleaner is negligible: rarely do they remove more than a few kilobytes from the total size of the registry. In fact, technology journalist Ed Bott has claimed that no-one has ever successfully managed to measure any significant performance increase from the use of a registry cleaner.[3] Any potential user of a registry cleaner must thus balance a probably negligible performance increase against a non-zero possibility of system instability.
Lastly, Microsoft does not advocate the use of these tools through its support website. This post has been edited by Nomak on 6 Apr 2008, 18:22 
WinXp Manager/ TuneUp Utillties, რას იტყვით ამ პროგრამებზე?
