Clean My PC“There’s something wrong with my computer. How to make my computer faster?” is a question a computer technician hears all the time. So you have a look and discover a perfectly good computer that needs nothing but a bit of cleanup from malware and junk, defrag, a scan with a registry cleaner, and some minor tune-up.

When you say to the customer that his or her computer needs a good cleanup and ask how often the PC is cleaned, the customer looks totally bewildered and says indignantly: “It can’t be that dirty! I clean my computer with a duster every time I clean my house!” Right. So you start explaining that you meant a different type of cleaning where malware, junk files, and redundant registry entries are deleted. The customer listens attentively and then comes the next question: “But why should I clean my PC???”

So, here goes – some FAQs for novice computer users and everyone who wants to improve the productivity of their Windows computers.

Why should I clean my PC?

A lot of people will tell you that cleanup is one of the most important parts of computer maintenance. And for a good reason. Daily computer activity, such as opening documents, browsing the Web, chatting on Skype, and even booting your Windows creates temporary files. These files are needed for smooth computer operation. But there is a problem – temporary files are often kept for a lot longer than necessary and can remain on your hard drive for months. As a result gigabytes of space are wasted and your computer becomes slow, because Windows needs longer to find the files you need amongst all that clutter. That’s why you should clean your PC on a regular basis to speed up computer performance.


How often should I clean my PC?

That depends on how actively you use your computer. If you only use it for basic stuff 2-3 times a week, then cleaning your computer once a month is enough. But if you are an active user, spend a lot of time online, and like to try out new software, you should clean your PC once or even twice a week.


What is registry cleanup?

Registry cleanup is a process where you remove redundant and empty entries from the Windows registry – the core database of Windows. Cleaning your registry makes your computer more organised and speeds things up. The easiest way to clean your registry is to use a reliable registry cleaner.


Why is it important to clean my registry?

The registry is the main database within Windows. It stores the settings for pretty much everything – operating system software, all your hardware, your applications, and all user settings. Programs on your computer access the registry thousands of times per second. As time goes by and you install and uninstall software, the registry accumulates obsolete entries that are no longer needed, like bits and pieces left behind by uninstalled software. These redundant entries slow down registry access and can even lead to various Windows errors. That’s why you should clean your registry to ensure top computer performance. The best way to do it is to use a good registry cleaner.


How often should I clean my registry?

As a rule, you should clean your registry every time you uninstall software or hardware devices. In addition to that, it’s good to scan your registry for errors on a weekly basis and fix them as they occur.


What are the best tools to clean my PC?

There are many tools you can use to clean your computer from junk files – even the built-in Windows Disk Cleanup utility would work. Also there are lots of decent registry cleaners available for download. You can choose to download separate tools for every aspect of computer cleanup, but it’s always better to use a software suite that has all the necessary utilities to keep your computer clean, fast, and optimized.

It’s your choice which software to use. Just follow the golden rule of choosing software – always download from reputable sites and always check user reviews before installing or buying an application.

Now you know how to speed up computer by cleaning Windows.

    In recent months I have been searching for reliable pc cleaning and registry programs. I have found most of them utterly useless. I have even paid money to a number of companies for a service such a registry clean, booster, advance system clean and have ended up in a real mess. Now I am having trouble with my internet security program. Something on my pc is preventing it from working properly. Being a aussie pensioner I can’t afford alot. I need some sound advice. If your programs works. Show me. I am sick to death with pc companies ripping me off. Can you really help me. I am interested!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! You can contact me at the above email site.

    I love your products.I have one problem if you can help me its driving me nuts.I have your auslogics defrag works great.The system health show 3 different functions junk registry and security.I always get all green no red.Untill i downloaded umplayer and still had perfect score until i unistall umplayer .I get 9 red registry errors So i install umplayer back so now i have two red registry errors but never have perfect again.Some people think the system health is just put there to get you to buy boost speed.I disagree.I believe the system health on auslogics defrag does work.But umplayer leaves leftovers on your computer when you unistall their product.Have not found any registry or unistaller to get rid of those left overs so i can get all green again on system health. i use auslogics registry did not work.So i downloaded boost speed to try it for 15 days but you don’t get the complete package until you pay.Now i unistall other products on my computer and run system health and get all green Only umplayer that shows registry errors in system health.If i reformat my computer that would fix the problem.

    Disk Cleanup.
    For the hard drive this is done on re-boot. On completion the result (at least I think that’s what it is) comes up with the speed of light and vanishes as quickly. Is there any way of retrieving the results in a time frame that is not measured in nano-seconds?
