Windows 7: Registry cleanup

10 Nov 2013   #1

Registry cleanup

Hello. I've been using Windows 7 Home Premium and I wonder, do we really need to clean up the registry, or just leave it untouched. I'm currently using CCleaner for clearing up junk files and registry and I wonder if it actually good for the system and is it really necessary.

I did some research on Google but didn't find an answer that really satisfies me. Hoping some good feedback from you guys.

I never clean my registry. I've heard (here, actually) that it's unnecessary with Win 7. Too many things can go wrong with registry cleaners. I learned my lesson having to do a reinstall of Vista, so never again.

Others may disagree, but I've never had any issues not cleaning it.

If you do clean the registry just be darn sure of what you are doing, it's easy to fubar it. Considering the size of the registry cleaning up a few hundred files is a gnat on a elephant. Not worth the risk IMHO, unless you very familiar with the registry. Do a backup first.

Registry cleaners generally cause more problems than they solve and should be avoided. The problem is that it is rarely possible to determine with 100% accuracy whether a registry entry is in error or unnecessary. Thus a registry cleaner must make numerous guesses. Most will be correct, but some are not. And there lies the problem.

There is little evidence that regular registry cleaning has any significant benefits and much that it does not.

Registry cleaners do have some value when used by an expert to solve a specific problem. But most people who use them have only a vague idea of what the registry is. A dangerous combination.

Wow, I guess I'll just leave the registry alone then. Thanks for all your feedback

If your computer runs well, just leave it untouched. If there something wrong with your computer referring registry, back up your whole registry first, then confirm the detail before cleaning.

Do as the saying goes: If not broken, do not fix it.

lol.. The ads for those registry cleaners claim your PC will be blazing fast after a through cleaning, but I doubt if any extra speed will be noticed (that is if your "clean" PC still boots up!).

In these adds the registry is often compared to a pipe that gets clogged up with unnecessary or bad entries and slows your computer down. But the analogy is bad and the conclusions invalid. The registry is a database. Unnecassary entries have virtually no effect on performance.

Years ago I head of a test where a registry was deliberately bloated, far beyond what would happen in a real world situation. Benchmarks of registry access times were done both before and after. The differences in performance were minimal. Note that the benchmarks were for registry access time, not overall system performance. In most cases registry access time has little influence on performance. Even seriously slow registry access time would go unnoticed.
