Network world has an interesting article about how Microsoft is pushing hard to get everybody off of IE6. They describe some really good reasons to upgrade. It got me thinking about why people still have the IE6 browser at all?
With a bit of research, here are the top reasons why so many people still have IE6:
1. Certain commercial apps do not support newer versions of IE without major upgrades. With funds for maintenance and upgrades slashed during the recession, it may be very difficult to obtain the necessary dollars to get the latest version of vendor software that supports new versions of IE.
2. Some internal apps do not support newer versions of IE. IE 6 offered a proprietary API that is not the same as current versions. If your development team has moved on or did not upgrade, the necessary knowledge of how to upgrade your application may now be missing.
3. IE6 uses less RAM then later versions – installing a new browser version may require you to upgrade the hardware or sacrifice the performance of other more critical applications. This cost factor encourages some to delay the upgrade.
4. Long refresh cycles – some industries do not refresh their technology until about 5 to 7 years of usage. Those of us in technology live around it and want the latest and greatest but, not everyone needs the most advanced technology immediately.
5. This does leave out the groups of people who simply have not upgraded because they don’t care to do any updates and those who ignore all new browser versions for various reasons.
If you haven’t made the leap, consider evaluating your situation and creating an upgrade plan that gets you off of IE6 before 2014 when Microsoft stops supporting XP and IE6. After that, no more security patches for new vulnerabilities.
