Re: What's the skinny on Registry Cleaners?
I have expert knowledge of the registry and, for the most part, know what is safe/unsafe to wipe out and I still rarely use them. When I do use them, I wonder why I even bothered, as they never really speed things up and you are left with a feeling of letting a thief into your house, wondering what was removed.
I'd suggest just using msconfig to remove needless startup items and doing a full reload of your PC if things are getting slow enough to make you wish reg cleaners actually benefitted you.
Living by these two rules has helped me live without a slow PC:
Don't install something you won't use over the long term
This means never install trial-ware or software you haven't researched already. If you are crossing your fingers in hopes a program will do what you want, you are asking for a slow PC. Read reviews, top 10 lists and forums first. You will quickly realize which software does what you want well before running setup.exe.
Buy RAM
When your PC runs out of RAM, it begins to use your hard drive as additional memory. While this is great failover, even the fastest hard drives (which you don't own) are 20 times slower than even crappy RAM. You may have an old, slow PC, but RAM will always benefit you. Better yet, most times RAM can be moved into whatever new PC you buy down the road, so putting in the cash now can benefit you for years to come. $40 can buy you 4GB of RAM, enough to run nearly anything.
I suppose a good 3rd rule is.. only reboot when needed. This is a personal choice, as it means running your PC 24/7, but I have found rebooting only when direly needed seems to keep things snappy. I reboot once every 2-3 months (usually because of driver or MS updates). Windows only becomes unstable over the long term because of the junk we install on it, not because of Windows itself.
