What are Invalid Entries, how did I get them, and what problems can they cause?
Invalid Entries are registry or configuration file entries in your computer's registry that refer to files that cannot be found.
Over time, Invalid Entries build up in your computer's registry from applications that do not cleanly remove temporary items and settings they store in your registry.
Some Invalid Entries, if present, may cause computer problems such as slow computer performance, slow startup, or error messages in applications.
If you're like most people, you probably noticed that your computer seemed a lot faster when it was brand new. The slowdown in performance may be caused, in part, by Invalid Entries continuing to build up in your registry
I think your computer became slower and slower because your computer system is fully of program or there is one of your computer program make your system became slower,your antivirus is the example. Because, I ever experience my computer became slower cause I have install a product of antivirus then my computer system became slower when booting and to open my computer program. Or you can maintance your computer with disk clean up to remove your unimportant program. And you must check your disk that memory isn't full and I think it can make your computer work more faster.
Some registry cleaners are worthless, and some even harmful. But others have established good reputations for efficacy and safety. Stick with the well-known names like Ashampoo WinOptimizer, Advanced Windows Care, Glary Utilities, Premium Booster, CCleaner, and nCleaner, to name just a few that I have tested for my utilities blog, with good results. Most of these come in both free and pay versions, and the free version usually is quite adequate. Ashampoo's current version is shareware, but you can get an older version free.
I found that my mother's Windows installation gets nastily cluttered over time. I bought a license for RegClean - maybe slightly more than 5 minutes, all the obsolete registry entries were removed and I was quite impressed with the sudden boost it gave to her laptop. There are some free reg cleaners available as well:

I have registrysmart and pc optimize 2.0 and they both work good. They both scan for free to see how many errors you have but you cannot clean them till you buy it. The website for registrysmart is www.registrysmart.com and the other one is www.pcpitstop.com. PC Optimize scans your internet connection for a faster connection. Also you can try Window Vista Home Premium. You also can put more RAM in your computer. Another suggestion, go to run and type msconfig, click on the start up tab and uncheck the items you do not use.
I have using RegCure for two years with no problems running the XP and Vista (recently). It allows you to create a "restore point" whenever it runs in case you do need to undo it. It also each and every line it is going to fix/remove. I personally noted increased performance after the first few cleanups, others don't.
You also get XoftSpySE bundled with it which is an anti-spy program for $19.95.
Good Luck,

Yes, it is true that if you have installed lot of programs and then uninstalled they might left some data on the registry.
But there are some other issues that slow down the computer among them there are two possible cases:
First case is that if you HDD is almost full then computer normally runs slowly.
The second case is that data on the disk might be so fragmented so would need to defragment it ASAP.
My suggestion is to use Norton Utilities so it could fix all possible problems with your computer
I looked at a few post here and they all seem to be real good ideas. For me when the computer starts to slow down I first look at how much space there is left on the hard drive! If its less than half then the OS swap file gets to little and can't do its job good. First go into your add and remove programs menu and get rid of some of those old programs you don't you any more. Save a few those my doc's, picture's, music mp3's or what ever onto a CD. Then run the disk cleanup wizard in windows. After you completed that run defrag also. Next will be to run the utility in windows called MSCONFIG. There you will find a tab at the top thats says STARTUP. You can safely uncheck some of the items in there that get booted up when you start your computer. Outside of adding another harddrive and Ram for your computer. Thats about it. Good Luck!
I might sound like a complete ass replying to all these posts, but I just keep hearing nonsense.
"For me when the computer starts to slow down I first look at how much space there is left on the hard drive! If its less than half then the OS swap file gets to little and can't do its job good."
So let me get this straight: are you saying that if on a 40GB drive, 25 of that is used, the OS will start to slow down because there is not enough room for a page file? Well, only if the user has 12 or more GB of RAM!
Honestly. Stick to just using the computer rather than trying to offer gold star advice. I've used my laptop with often less than a GB left of the 40GB drive, and it's not affected performance hardly any - if at all.
you're right! memory always lag behind speed... according to my idiot teacher... hehe...
My system is equally old and I had the same problem with it slowing down. I tried all the different cures but none really worked. In the end I copied all the important stuff to another drive and discs, formatted the drive and reinstalled the operating system from the recovery discs I made when I bought the machine. Final result a machine that worked as it did when I bought it. On the down side it took a long time and a few programs were lost as I did not have the discs (bought as downloads). On the up side I found a few suppliers who let me have the download again for free once I proved that I had bought it from them in the first place.
Doing it this way I also cleared a lot of programs bought to try and left sitting on system never being used.
Sorry, but that could have been solved by using MSCONFIG, visiting ADD/REMOVE PROGRAMS in the Control Panel, and using CCleaner.
You did not need to format and reinstall that computer.
It is my opinion that the registry is best left alone unless you have an annoying context menu (the additional menu that pop up when you right click on an icon) or serious error that uninstalling a program just does not help. If you have been running on the same xp install for 5 years I applaud you. I usually only make it about a year or two before the applications, hardware and drivers that I have installed, tested, uninstalled begin to leave too much clutter that I wipe my hard drive and reinstall a fresh clean xp install. I have done this enough times that I can usually have a fully working machine (ms office apps, adobe, drivers, updates and the rest) within 5 hours. I would recommend that before tweaking the registry as it will do a much better job of giving you the machine you had when you first purchased the computer.
That being said, should you wish to continue the first thing you should do is make a back up of the registry (the complete registry is housed in the windows directory usually looking like this C:\Windows\System32\config; these files are hugely important, if the are deleted or damaged your computer will most likely not boot anymore). My favorite tool for backing up the registry to a separate location is ERUNT. It is free and a useful tool, a google search usually brings you http://www.larshederer.homepage.t-online.de/erunt/ . Go into the detailed information and scroll down to "What to do if Windows does not boot anymore." If recovering from a backup in the scenario seem a little crazy I probably would not play with the registry.
After your backup, my two favorite automated tool are CCleaner and PCTools Registry Mechanic. CCleaner is free and Registry Mechanic is 30 bucks. CCleaner does a cursory search though the registry and offers a checkbox entries on problems with the registry problems. It leave it pretty much up to you to determine whether to fix the problem or not and does not offer much suggestion on what the entries are. Registry Mechanic offer a more comprehesive check and cleaning but does not give much infomation on individual extries. In my experience these have given me the least problems and offered an ease of use; but I have fallen out of use of them and find that clearing out windows offers better performance benefits.
Download CCleaner from CNet and make use of it to clean your system
No sweat Tom S ,you don't have to dig around in it your self,most
registry clean-up programmes do it automatically .I use one called
Fix-it utilities Express 7. Available from ( in UK ) www.avanquest.co
.uk/vnu/fixit. This has other clean-up items attached,although my
version was on limited offer via a computer mag. Also try the magazine
site I use in the UK for most of my freebee downloads address is:
www. computeractive.co.uk , I also use "Free windows registry repair"
but can't remember where I got it from,must of the freebees I use
come from Cnet.Hope this may help,DanC Surrey UK
