Microsoft is always proud of announcing just how much faster each new version of Windows is, compared to the previous one. It's true that, if you upgrade to a new version of Windows your PC will run faster. But in many cases, the speed-up is nothing to do with the new operating system. It's simply that, the more you use your PC, the more it gets bogged down with old files and unnecessary registry entries. And it's these which are largely responsible for the slow-down, rather than the upgraded OS. You can see it for yourself if you wipe your computer's hard disk and install a new copy of the same version of Windows that you had before. The makers of the world’s most popular PC and Mac cleaning software bring you CCleaner for Android. Remove junk, reclaim space, monitor your system and browse safely. Do I need to uninstall the old version of CCleaner when upgrading? No, you can install newer versions over the top of older versions, without having to uninstall. If you do uninstall an old version first, you will lose your existing settings. Your computer will almost always run much faster. But then, of course, over time, it will slow down again as the detritus builds up. There are many programs which claim to be able to clean up the mess that Windows continually accumulates. Probably the best known is CCleaner, made by Piriform. Download stupid zombies for mac free. While the full version is a paid-for product, the basic free edition is still very powerful and worth investigating if you've never tried it. The most recent update to CCleaner was a couple of weeks ago. And as well as the standard installable version, there's also a portable edition which runs without installing anything. So if you don't like it, or don't intend to use it regularly, just delete the downloaded files and all traces of the software will be gone. Although the portable version of CCleaner is not on the main download page, you'll find it listed at and it's a 6 MB download. The program is malware-free according to VirusTotal and Web of Trust. The program has 2 modes. First, it analyzes your computer in search of things that it recommends you should tidy up. A single click of a button will then do all the hard work for you. You can choose which recommendations to accept and which to reject. Please rate this article. For those not familiar with it, CCEnhancer is a very useful addition that extends the range of CCleaner's cleaning abilities -. To echo, and build upon, zdub's comment about the Registry, a quick web search will confirm his advice. Whatever infinitesimal speed-up might be had from 'cleaning' the Registry is FAR outweighed by the potential (perhaps even not unlikely) damage (as in catastrophic) that can be done by the wholesale deletion of entries. For those who simply cannot sleep at night due to obsessing about those orphan Registry entries, then make dead certain to set a Restore point AND make a full backup of the Registry before 'cleaning' it (a full system backup is not a bad idea, either.). But again, the best practice is for the vast majority of Windows users to simply leave the Registry alone. • or to post comments. At the margin of PC performance 'unnecessary registry entries' can contribute to slow down your system. It is easy enough to slow down Windows by depriving it of enough memory to function properly. Many people have shown this including articles on this site. MarkRussinovich's comments about the registry in Windows XP were specifically about slowing down the registry rather than slowing down the PC. Because of the way it is designed to run there is no measurable impact on registry performance unless the memory it uses is severely constrained. At that point, Windows will have ground to a near halt anyway. • or to post comments. It is not that hard to produce a measurable improvement in system performance following registry cleaning in Windows XP. The question of significance depends on the user and their system. The more constrained your system memory or the older the version of Windows than XP then the easier it is to show measurable improvements. That was why I said 'at the margins' because the average system configuration will not show any noticeable improvement. I wouldn't even bother testing Windows versions later than Vista because Microsoft has further enhanced the registry performance since XP. The more that desk jockeys spread the myth that there is never any benefit from registry cleaning then the less likely it is that a web search will produce relevant results. On the other hand, as XP and earlier versions of Windows diminish in signficance then registry cleaning has less relevance. I at least took the time to run real world tests and provided a summary of some of that work here. Similar performance improvements have been reported elsewhere but some required a paid subscription.
