One of the most persistent myths about Windows is that you need to reinstall the operating system regularly to keep it running at top performance. Let’s take a look at the real problem and how to fix it.

Today we’re talking about the myth that Windows slows down over time, and how to solve the problem. The reality is that Windows doesn’t slow down if you just take care of your PC a little more. Follow these procedures, and you won’t have to wonder if spending hours backing up data, installing from disc, and re-installing your essential applications is really necessary.

What Does Slow Windows Down Over Time?

I’m not going to sit here and tell you that your Windows PC will never slow down—because for many people, they almost always do. What actually slows your PC down are too many poorly written applications that stay resident in memory and waste CPU cycles, having too many badly written low-level applications that hook into Windows, or running more than one antivirus application at a time. And of course, if you’ve run your PC’s hard drive out of space, you can hardly blame Windows for that.

If you aren’t getting the picture, the problem is usually the person behind the keyboard that installed too many junk applications in the first place. More gently put, it’s often that (very well-meaning) person’s gradual easing of their safeguards and cleaning regimens as time goes by.

Stop Installing Junk Applications

Installing software should be thought of like feeding your PC. If you constantly feed your PC garbage apps, it’s going to get sick and won’t be able to run fast anymore. These poorly written applications clutter your drive with unnecessary DLL files, add always-resident Windows services when they don’t need to, bloat up your registry, and add useless icons to your system tray that waste even more memory and CPU cycles. Usually you can get away with using a few terrible applications, but as you continue to install more and more of them, your PC will slow down to a crawl.

Be Smarter About What You Do Install

We feature and recommend a lot of software applications around here, but you should keep in mind that we aren’t trying to tell you to install every single one of them at the same time-just install the applications that you actually need and you’ll generally prevent the dreaded format and reinstall.

Here’s a few tips to help you know what applications you should be careful with:

• Apps that function as an Explorer plug-in, because they directly hook into the shell and any problem will make your entire PC slow or in the worst case, crash repeatedly.
• Antivirus applications are notorious for slowing your PC down, and you should never, ever, ever use more than one real-time antivirus application at a time. We recommend Microsoft Security Essentials as a free, fast, and awesome antivirus tool.
• Anything that says it will “Speed Up Your PC” or “Optimize Your RAM” will most likely slow it down, or best case, do nothing at all. Avoid these like the plague.
• Make sure to install official system drivers from the manufacturer website. Drivers have a huge impact on performance, and you want to have stable, updated drivers.
• Registry cleaners are a mixed bag, and really aren’t going to speed up your PC in most cases. The biggest problem, however, is that too many of the commercial registry cleaners set themselves to run at startup in the system tray, wasting your memory and CPU cycles.
• You should strongly consider the idea of using portable applications wherever possible, since their self-contained nature means they won’t clutter up the rest of your PC with things you don’t need.

Keep Your Computer Clean and Trim

Once you’ve rid yourself of your junk application habit and resolved to only use healthy, useful applications, you’ll want to make sure to keep your PC clean of any remaining clutter that doesn’t need to be there. You can set up a shortcut to manually run CCleaner silently with the push of a button, but your best bet is to set up CCleaner to run automatically on a schedule, so you don’t have to remember to do it.

Since CCleaner is only going to clean up temporary files, you’ll still need a good solution for keeping the rest of your PC clean-and Lifehacker’s own Belvedere can help you automate your self-cleaning PC or automatically clean up your download folder.

With all of this automated file deletion going on, your hard drive is likely to get a bit fragmented. If you’re already running Windows 7 or Vista, automatic defrag comes out of the box and probably shouldn’t be messed with, but Windows XP users will need to use Windows Tasks to setup a schedule and automatically defrag their drives.

Use a Virtual Machine or Sandbox to Test Software

If you still want to test out all of the latest software, including apps that look a bit rough around the edges, your best bet is to use a virtual machine to test out anything before putting it onto your primary operating system. You can install all of your software in an XP or Windows 7 VM just like it was a real PC, and with the latest VMWare player releases, you can even enable Windows Aero in a guest VM. If you are new to the idea and need some more help, you should check out our beginner’s guide to creating virtual machines in VirtualBox, or Windows 7 users can check out our guide to using XP Mode. If you don’t want to go the virtual machine route, Windows XP and Vista users can alternatively use Windows SteadyState to protect their PC and roll back all of the changes on a reboot.

Local Security Authority System Service, or lsass, is the Windows process responsible for authenticating user passwords, logon algorithms, user permissions and groups, local security policies and writing the Windows Security Log. An lsass error can mean users are not able to logon, or are not able to gain access some applications and files. In order to fix an lsass error, first of all you should know the cause of the error.

There are two primary reasons that can bring about lsass errors, system based troubles, or outside malicious influence. The primary area to look for the root of an lsass error is for outside malicious influence. The crucial tasks of lsass algorithms make it a priority target for Trojans, worms, adware, spyware, and keyloggers. The most despicable of the worms targeting the lsass process is the Sasser worm. The Sasser worm is recognised for its cruelness and power to duplicate without any human interaction at all, email is unimportant. One positive sign of a worm copying the lsass process is the computer will shut down and reboot continually, about once a minute, without ever getting to the login screen. The best action to solve the trouble of vicious software causing an lsass error is a careful and complete malware and spyware scan.

However, if an infection is not the origin of the lsass error, fixing it would be more tricky. System based errors can works with|have many caruns with|come from number of caruns with[/spin], but are usually from either a destroyed or missing dll file, or from an abrupt termination of the lsass process. Most of the processes on a computer runs with dll files. Most dll files are utilized by more than one process. Generally speaking this is not an issue until one of these dll files is destroyed or unintentionally deleted. When it becomes the case, any other process that rely on that certain dll file will not be able to function properly, or will not work at all.

Repairing a system based lsass error requires editing Registry files, and other complex operations. Trying to edit registry files manually is very risky and if not done exactly right, can add up even more troubles. Manually editing the Registry files is a solution only for the most advanced computer users. For most computer users, there are numbers of registry scanners sold online that can locate and sort out registry errors easily.

The rundll32 file is the bridge for your dll files and all the peripherals, programs, and devices attached to your computer. A dll file, or dynamic link library, is a file that multiple programs utilize synchronously. For the purpose of making computers run more efficiently and use less computing resources, dll files include code that several programs may need. Programmers, instead of putting the same bit of code in every program they write call on dll files. Instead of having numerous programs with the same codes, dll files allow you to have one copy of the code, and several programs employing it. Dll files can also shoulder background tasks that are necessary for a fluent and secure movement of your computer..

The rundll32 error can be caused by several unlike causes. Everything from a hardware or software conflict to viruses, worms, or Trojans can cause rundll32 errors. These error messages can come at any moment when something is attempting to access the dll files, like startup, loading a program or application, or shutdown. The majority of rundll32 errors are from a corrupt or missing dll file or driver somewhere that is causing another program to run improperly.

Amending rundll32 files can be fairly simple however. Downloading and running a registry cleaner can solve the problem. The Windows registry is one of the most important parts of your operating system. It keeps data needed to nearly each program on your computer, including the operating system, any attached hardware, and also contains per user settings. Any alteration to your computer, such as installing or deleting software, new hardware, or a simple change in user settings affects the registry.

Typically, rundll32 errors can pin point which file is missing or corrupted, but for the typical computer user, manually editing the registry files can be dangerous. Changes to the registry may result to even more problems than you started with unless you really have an idea on what you are doing. Using a registry cleaner can fix any corrupt or fault entries in the Windows registry, and should solve the rundll32 errors.

After completing the registry cleaner scan, consider running a thorough virus scan and an anti spyware. This should eliminate any viruses, Trojans, worms, or other malicious software that may be causing the rundll32 error.

Iexplore.exe file is not a virus, Trojan, worm, or spyware. It is an executable file of the web browser program, Microsoft Internet Explorer. This .exe file contains the graphical user interface composed of all the webpages that you have viewed on the Internet. Once you enter a URL in the browser’s address bar, the corresponding webpage is displayed on the screen.

Utilizing the Trident layout engine and Component Object Model (COM) technology, iexplorer.exe was created to support a huge number and variety of webpages, as well as different features of the Windows operating system, such as Microsoft Update. It is made up of 5 main parts separately housed in .dll files and COM interfaces, all of which run on  Internet Explorer’s .exe file.

In some cases, if your computer has other browsers like Mozilla Firefox installed, you may encounter iexplore.exe errors. These errors occur in cases where other software programs that have been integrated into Internet Explorer incur errors themselves. On the other hand, some malware, adware, or spyware may make their entrance into your system hiding behind some legitimate programs you have downloaded. There are also some websites on the Internet that load various small programs into your system each time you visit them, and these can cause errors, as well.

The best way to prevent any entrance of spyware or adware into your computer is to regularly run security checks on your system, as well as configure your anti-virus program to do a regular full-system scan. Adware Alert review software Malware Removal Bot review will both carry out a thorough system scan and screen your PC against malicious threats. Obsolete files or old programs that aren’t used anymore are best removed in order to prevent the occurrence of these .exe errors in the future. Another solution is to run regular free performance scans to optimize your Internet settings, memory, and CPU.

If Internet Explorer remains the browser of your choice, disabling iexplorer.exe isn’t recommended as it will effectively prevent you from running the Internet Explorer browser to view webpages on the Internet. 

.dll i.e. dynamic link library files are the files in your system that create the link between the system and other common files. A rundll.exe loading error message occurs in case there are any changes in the location of .dll files in the pc. This message displays durring start up. Did you know that when you install or uninstall programs, shared .It is possible that dll files may be renamed or moved by accident. The system can experience a slow down as the registry attempts to find the file. If the file has been deleted or cannot be found a rundll error loading message pops up on the screen.

Believe it or not, sometimes just rebooting your computer may resolve the problem. It is also possible that malware i.e. spyware or adware in addition to viruses could be responsible for the error messages. So it would be helpful if you run an anti virus and spy ware scan on the system first to check and rule out this possibility first. It is a good idea to reinstall any recently removed programs. It may be that this caused the error. Later you will want to uninstall the program with the add/remove programs option in the control panel.

You can locate the corrupt file by using the run command MSCONFIG. When a .dll file is installed there are updates in the registry. There are several hundred dll’s on your system, and it can be very time consuming to attempt to find the corrupted file. Registry records are viewable by typing ‘regedit’ in the run box. The information is stored as six HKEY folders. It is not recommended that you try to repair the error yourself, or further system damage could occur. You can do damage to your system by accidentally removing an important registry key. Eventually you might find that you are not even able to boot the system.

IT technicians have software and registry cleaners for correcting these errors. If necessary, you can hire a pro for a fee to repair the problem for you. Another alternative is to use the software the professionals use. Well known registry cleaning software include Register Easy and RegClean. This helps you to find and isolate the files that are missing or currupted and reinstall them. Scanning your registry once every six months will help to keep it organized.  See how the top registry cleaners stack up
