Even though you may be using the latest and greatest version of Microsoft's Internet Explorer, version 7. x, you may inevitably encounter problems that render your web browsing experience to be excruciatingly unproductive.
Pages may take a very long time to load, even though you are a high-speed Internet connection. Loading certain web pages may cause your browser to crash. Your mouse cursor morphs into the infamous hourglass, an unwelcome omen foretelling an imminent need to reboot your PC, as your entire computer has frozen up!
You may be led to believe that your computer has been infected with a virus or with spyware. But more often than not, the problem with Internet Explorer persists even after you have scanned your PC for them.
More often than not, the prognosis is that your PC's Windows registry has become corrupt, and is in dire need of repair and optimization. The Windows registry is your operating system's master database that stores all of the information about all of the software, hardware, user profiles, network settings, operating system behavior, mime types, and system security associated with your PC. Over time, as you install and uninstall programs, add and remove hardware from your machine, and download files from the Internet, errors can start to creep into the registry.
Internet Explorer, like everything else on your system, relies heavily on the registry to lookup and to update information. If there are errors in the registry, or if the registry is unoptimized, this can cause Internet Explorer to slow down and even crash. And this instability can spill over to the entire operating system, causing your entire computer to run into problems.
The best thing to do when this occurs, is to run a free scan of your Windows registry to repair it.
