This morning, I am unable to log in to Hotmail. The homepage appears normally, but after I enter my email address and password and click to submit them, a window pops us asking me what to do with the file "default.aspx." I have a Vista machine, and last night my computer automatically installed a ton of Microsoft updates. In fact, the update list shows that one of the updates failed to install. At the end of this message, I have pasted the details of the failed update. I have checked the Hotmail support forum, and someone else posted that the have experienced the same problem this morning. The Microsoft "expert" asked him or her to contact Mozilla for support for this issue. Thanks in advance for whatever help you can provide, although I highly suspect that this is a problem on the Microsoft/Hotmail end, not yours. Here is the info on the failed software update from last night... Security Update for .NET Framework 3.5 SP1, Windows Vista SP2, and Windows Server 2008 SP2 x86 (KB2478660) Installation date: ‎6/‎16/‎2011 12:01 AM Installation status: Failed Error details: Code 80242006 Update type: Important A security issue has been identified that could allow an attacker to compromise your Windows-based system that is running the Microsoft .NET Framework and gain complete control over it.
