Internet Explorer 6.0 SP1 is an updater for Microsoft’s IE version 6. This particular service pack addresses general improvements and is recommendable that you install it.
Internet Explorer 6 is Microsoft’s default browser that is being shipped with operating systems such as Windows 98, NT, Windows ME, Windows 2000, XP and 2003. Even though IE has now reached its tenth revision, Microsoft still distributes IE6 with Windows XP 2003.
As such, this edition of IE is intended for users of XP and lesser operating systems. Being a service pack, it contains only the updates and fixes necessary to bring Internet Explorer 6 to the highest browser technology available for this particular revision. Installation takes no longer than a couple of minutes, but a restart is required in order to complete the operation successfully.
One question that seems to preoccupy a lot of users is why they should install this update, even though they are not IE users. The answer is very simple, in fact: as a consequence of updating the default browser, your operating system will be up to date, thus preventing all those alerts that state that your computer is missing some updates.
Also, a lot of browsers are IE-based, so their behavior depends entirely on Microsoft’s navigator – installing the updates could mean better performance.
We’d like to mention that even though the first release of IE 6 is compatible with Windows 2003, the SP1 package is not compatible with this OS, because the Server edition uses a special release that is not compliant with the standard distribution.
All in all, Internet Explorer 6.0 SP1 is a highly recommended update for IE6 users. The list of updates and fixes addresses all sorts of issues, including security, so do not overlook it.
