Registry Cleaners Demystified RELATED: Registry cleaners aren’t a magic button you can click to speed up your PC, as developers would like you to believe. The Windows registry is a huge database of settings — both for Windows itself and for programs you install. For example, if you install a program, there’s a good chance that program would save its settings to the registry.
Windows would also save pointers to that program. For example, if the program were registered as the default program for a certain file type, Windows would save a registry entry so it can remember that’s the default program. If you uninstalled the program, there’s a good chance it would leave all its registry entries behind. They’d stay in your registry until you reinstalled Windows, refreshed your PC, “cleaned” them with a registry cleaner, or deleted them manually. All a registry cleaner does is scan your registry for entries that appear outdated and remove them. Registry cleaner companies want you to believe that this would result in big performance improvements so you’ll buy their software.
The Promises Here are some promises that registry cleaner tools often make:. Registry cleaners fix “registry errors” that can cause system crashes and even blue-screens. Your registry is full of junk that is “clogging” it and slowing down your PC. Registry cleaners also eliminate “corrupted” and “damaged” entries. The following passage from Uniblue’s Registry Booster product page is a good example of the typical promises you’ll see: “Have you noticed that the longer you have your computer, the slower it runs and the more it crashes? Often this is because whenever you install or uninstall software, adjust hardware or change settings, the Windows registry is updated. Over time the registry starts losing shape, accumulating obsolete, corrupt and harmful files.
Left unchecked, your system can become increasingly unstable, run more slowly and crash more frequently.” Wise Registry Cleaner, which is thankfully at least free, says it can also “get your PC running more safely.” If your Windows PC is crashing or, you shouldn’t worry about “registry errors.” “Corrupted” and “damaged” registry entries also aren’t wreaking havoc on your computer, despite what the snake oil peddlers might want you to believe. If your registry is indeed corrupted, you have bigger problems and a registry cleaner isn’t going to fix it — you’d need to use, at least. There’s nothing “unsafe” about not using a registry cleaner. The leftover registry entries that accumulate naturally aren’t harmful. The Reality In reality, registry entries aren’t a drag on your computer’s performance.
The registry is a massive database containing hundreds of thousands of entries and individual registry entries are fairly tiny. Even removing a few thousand entries won’t make an appreciable dent in the size of your registry.
Now, if our computers only had a tiny amount of memory or an extremely slow hard disk, there could be some value to shrinking the registry a bit. But this will be completely unnoticeable on computers in use today. We don’t live in the days of Windows 95 anymore. The Windows registry has also become more robust as Windows itself evolved from Windows 95 to Windows 7 and 8. Windows just isn’t getting confused and slowing down because you have a folder (known as a “key” in registry parlance) dedicated to an uninstalled program in your registry. It also isn’t getting confused because certain entries point to an outdated program.
RELATED: No legitimate benchmarks showing a performance increase as a result of a registry cleaner have ever been released. If a registry cleaner offered boosted performance, we would have some benchmarks by now.
It’s anecdotal evidence, but the majority of our readers didn’t find that registry cleaners helped improve their performance on modern computers, either. In Some Rare Cases Now, it’s theoretically possible that a registry cleaner could help in some rare cases. For example, if a program left behind an invalid context menu entry in your registry, it’s possible that your context menu would take noticeably longer to appear in Windows Explorer when you right-clicked on something. It’s also possible that a registry cleaner would notice and remove this entry for you, solving the problem. In another case, you might have a ten-year-old computer with a very small amount of RAM and a Windows installation that’s seen thousands of programs installed and uninstalled over the case of a decade. A registry cleaner might theoretically help shrink the size of the registry enough to make the computer perform faster.
Abakada unang hakbang sa pagbasa pdf. Such situations are bound to be extremely rare. There’s no point in running a registry cleaner constantly — many registry cleaner companies recommend running their cleaner once a week. Such problems would be better dealt with by solving them when you encounter them. It’s likely that the average registry cleaner would cause many more problems than it fixes if it were run on a regular basis. And even if it’s completely harmless, it’s a waste of your time. So If a Registry Cleaner Won’t Speed Things Up, What Will?
We’ve already covered and shown you how to prevent this from happening. Rather than run a registry cleaner, you should just be careful about what you install in the first place.
Even if you need to uninstall something later, a few registry entries — or even a lot of registry entries — won’t cause a slow down. If your computer is hideously slow or crashing frequently, you likely have more problems than a full registry and you’re probably better off. We didn’t dwell on this part too much, but registry cleaners can also cause damage. There are so many different registry entries that could be present from so many different software programs that the average registry cleaner put together by a less-than-reputable software company can’t possibly account for them all.
If a registry cleaner tried to be too aggressive so it could clean up as many “errors” as possible, it could easily remove errors that were necessary for an installed program, causing problems. In summary, forget about registry cleaners and get on with your life.
As long as you take basic care of your Windows computer, you don’t have to worry about your registry.
In early 2012 I wrote this short article describing the impact of registry cleaning on Windows XP performance. I never published it because I was primarily settling the question for my own satisfaction. Secondly, I shelved it when I started working on a longer article that provides more detail on the scenarios. I never finished that other article so now I'm publishing this shorter article because it will still be useful to the many Windows XP users. Introduction Have you ever wondered whether registry cleaners do anything useful? Many people say that they do not.
Two articles that give you a taste of the debate are Mike Bott's ' and Mark Russinovich's '. It might seem that blog posts from 2005 are way out of date but Windows XP market share was only passed by Windows 7 in 2011 and even today Windows XP is number two on the desktop ahead of Windows Vista and 8, Apple OS X, and Linux.
There are two aspects of registry cleaning to be considered:. removing unneeded registry entries. the impact of registry cleaning on system performance There is widespread support for the first aspect. But it's not so clear on the second aspect. Mark Russinovich — the current co-author of 'Windows System Internals' and an acknowledged expert on Windows troubleshooting — is widely quoted in his response to the question 'do you really think that Registry junk left by uninstalled programs could severely slow down the computer?'
: No, even if the registry was massively bloated there would be little impact on the performance of anything other than exhaustive searches. On Win2K Terminal Server systems, however, there is a limit on the total amount of Registry data that can be loaded and so large profile hives can limit the number of users that can be logged on simultaneously. I haven't and never will implement a Registry cleaner since it's of little practical use on anything other than Win2K terminal servers and developing one that's both safe and effective requires a huge amount of application-specific knowledge. 10/7/2005 9:41:00 AM by Mark Russinovich This issue intrigued me so six years later when I had spare week of time, I made the only New Year's Resolution I have ever kept. I decided to benchmark the performance of the Windows registry to see if he is right. In the end I ran over 580 tests on 98 different configurations of hardware and installed software. I tested both a well-used, you might say trashed, computer and two computers I configured from scratch.
I used Windows XP because it related to those comments, it was the dominant operating system and the benefits of registry cleaners would be more obvious than on Windows 7 which is somewhat more sophisticated. To cut a long story short, two months after I started, I had what I needed.
So here is some of what I found. Conclusion YES, registry cleaners do make a difference but NO they do not normally make much difference. In fact the impact of registry cleaning was often less than the margin of error in my tests. It was consistent and measurable on my test systems but at an average around 1% it is close enough to zero.
I found that Windows XP users have other options that will have a much greater impact on their Windows performance. These are obvious things like the amount of physical memory or the number and type of applications, services and drivers installed on your computer. If you are in a hurry then Methodology While I was testing I read Fred Langa's ' where he found that system cleaners can provide a performance benefit for startup and shutdown times. He created a baseline system then installed the 20 most popular applications on CNET. He timed startup and shutdown and found that these activities now took from two to twenty times the base times. He then uninstalled all the applications and used three system cleanup utilities to attempt to return the system to something close to it's original state and performance.

Depending upon the system cleaner used, he succeeded in getting Windows startup and shutdown performance close to or better than his original baseline. It is a logical no-brainer that startup & shutdown, logon & logoff, and backup & restore will perform better with smaller registry files.
The registry hives will load more quickly if there is less registry data and the in-memory hives will be smaller too. I decided to cover some of the same ground and also looked at startup and shutdown times, 430 times. Those results largely supported Langa's and I will publish some details in a later article. In my own tests I was only focused on the interactive performance of the registry because that is what affects programs when you run them. I wanted to create the same sort of situation that users constantly find themselves in where their system slows down dramatically.
So the main differences between my tests and Langa's are as follows:. A broader cross-section of applications was installed using the top picks in the security, office, image and multimedia categories at this site. The registry performance was benchmarked using Bitsum Regbench, an alpha version.
This utility does create additional load on the system because it loads keys into memory. Normally, I wouldn't want that but but this time I wanted to simulate an overloaded system where registry cleaning would have the opportunity to produce more obvious benefits. Registry cleaning was tested by itself without any other system cleaning or registry optimization. I also separately tested optimization of the registry hive files rather than combining it with registry cleaning. I didn't use virtualization because it introduces another layer of complexity and variables that could confound small differences in performance.
Instead I used dedicated computers where I physically added or removed memory. In my preparatory testing, I found that the same issues that affect your applications also affect interaction with the WIndows registry. As I expected this suggests that the opportunities for improvement on your system will depend upon your specific configuration:. The available physical memory. The background load from installed applications, services and device drivers that consume three limited resources:.
CPU processing time. Available memory. Kernel-mode processing of the registry Results Got enough physical memory? As I said above, my conclusion is that Windows registry cleaners can produce a small and measurable performance improvement. I got a 3.9% improvement on one hive on one test but the average was only 1.3% even when I used several registry cleaners. Startup times improved by a similar proportion. To put this into perspective, I got thirty times that improvement simply by uninstalling one application, PC Tools Threatfire.
It reduced registry access performance by 37% because it monitors the registry. Uninstalling another application, SpeedBit sbupdate, and its companion gained me another 20% because of their registry monitoring or polling as it is called. I refer to Mark Russinovich who explains why. Table 1 - Registry performance improvements with enough physical memory.
Windows XP 32-bit 768 MB Optimize the registry hive files using NTREGOPT none Clean the registry with CCleaner 0.2% Clean the system, including the registry, with CCleaner 1.1% Clean the registry with several registry cleaners 1.3% Temporarily stop unneeded services 3.3% Turn off real-time anti-virus 4.7% Uninstall worst application 37% Uninstall three worst applications 57% Not enough physical memory? I then considered what happens if I don't have enough memory in my computer.

To make this more likely I increased the number of installed applications from twenty to seventy and found that I need 768MB to get a usable system because of all the services and start programs they installed. In a scenario with only 20 programs installed 256 MB was usable. Note that this is four times the Windows XP minimum system requirement yet the performance using the registry dropped by 21%. Likewise, startup times doubled, i.e. Increased by 100%, because startup is more dependent upon the installed memory.
If PC Tools Threatfire and the other two applications had still been running then the system would have crawled very close to a halt. This happened because without enough physical memory Windows becomes more dependent upon virtual memory. This enhances the benefit of system cleaning including registry cleaning because every bit of memory released can be used to boost system performance.

Do we really need Windows registry cleaners? The answer for users with enough physical memory is NO.
But if you are low on physical memory and continually having Windows paging virtual memory to disk then YES you should consider trying them. If you are $ constrained then it could help save you the price of a memory upgrade. Please rate this article.

or to post comments. Through over 10-years of trial and error via a myriad of software, as I am sure many of you here have your own experience as well, I have found a totally full-proof method that has literally maintained my Windows 7 to operate as crisp as brand spanking new, day after day, going on 5-years now without a single OS refresh: Daily just prior to Windows Shutdown I run the following: 1. removed as unacceptable content 2. CCleaner w/ CCEnhancer add-on,Registry Clean and Scan Clean; 3. System Ninja w/Registry module add-on, Registry Clean and Scan for Junk; 4. Jet Clean 'Detailed' scan. Once a week I run the following: 1.
Spybot Free; 2. SUPERAntispyware Free; 3. Malwarebytes Free. The aforementioned package contains no bs. spyware/adware, cleans everything to maintain maximum storage and keep the OS operating crisply, and locates and purges superfluous cookies, adware/spyware, trojans, etc. This statement is incorrect as both System Ninja and JetClean are bundled with unwanted components. See this page for more information: MC - Site Manager.
Finally, despite my observations that the mainstream view is that cleaning the registry does nothing to override the supposed inherent risks, I have absolutely resolved that view as BS. Cleaning the registry per the aforementioned methods have totally contributed to keeping my OS running smooth, snappy, and like-new-crisp year-after-year-after-year. or to post comments.
Thanks for the info. I am interested in your experience and that you've had no problems. We normally only hear about problems. I don't know of anyone who does what you have done because running so many cleaners is quite extreme.

Updated: by Computer Hope Registry cleaners are designed to help remove invalid references in the Windows registry which point to a resource which no longer exists on the computer. These resources may include, programs, fonts, uninstalled programs, or system information that is out of date.
These references can be left behind when a program is not uninstalled properly, the uninstaller is poorly written, or the system has crashed in the past causing these invalid entries. Although these utilities can make the Windows registry clean, the overall potential benefits are greatly outweighed by the potential harm they could cause. We suggest users do not install or use Windows registry cleaners on their Windows computers. Can running a registry cleaner cause problems?
