And corporations can't leave Windows XP for Windows 7 until IE6 runs (in some way) on Windows 7. Microsoft wants to leave that non-standard browser mess behind them, but as the article notes, 'Organizations running IE6 have told Gartner that 40% of their custom-built browser-dependent applications won't run on IE8, the version packaged with Windows 7. Thus, many companies face a tough decision: Either spend time and money to upgrade those applications so that they work in newer browsers, or stick with Windows XP.' Support for XP is going to end in April 2014. In order to deal with this, companies are looking at virtualizing IE6 only (instead of a full operating system) so that it can run on Windows 7 — even though Microsoft says this violates licensing agreements. IE6 is estimated to have roughly 16% of browser market share, and due to mistakes in the past it may never truly die."
