From some time back, I have been very keen to look into the effort Microsoft provide in doing the post product launch fixes. As a SharePoint Architect, i remain eager to dive deep into these CUs and SPs.

If i give you some example from recent Decemeber  2011 CUs, and the minute fixes provided by the Microsoft is quite fascinating. That’s why this product beats all of the competitor all the way. Following are the some of the examples

1.   The English spelling checker does not recognize the word “Lync” in SharePoint Server 2010
2. When you try to use an Apple iPad to visit a dashboard in PerformancePoint Services, the context menu is not displayed.
3. The XSLT List View Web Part displays an incorrect date format on a SharePoint Server 2010 website if the website’s region setting differs from the SharePoint server’s region setting.

As per the precaution and best practice, dont apply these CU’s if you are experiencing the problem resolved in this CU as per the CU description plus dont try to execute it directly on live server, first check on your dev or UAT. Because these CU are very specific to problem listed in the CUs.
