SOLVED: What Is the Difference Between Microsoft ‘Mainstream Support’ and ‘Extended Support’

If you have been getting worried about your Windows OS running out of support, you might be confused by the terms.

dead-windows-7-vista-mainstream-vs-extended-supportThe basic difference between Mainstream Support and Extended Support is payment for phone support.  Extended Support does not allow companies to get free (well, no additional charge) telephone support from Microsoft.  Companies have to pay for phone support when a product is in Extended Support time frame.

Under both Mainstream and Extended support Windows Update still functions as you would expect with security patches and various other fixes.  Clearly Microsoft will not be putting much effort into the ‘fixes’ for their old products in Extended Support, but they do release a few when the issues are big enough.

Microsoft explains the difference in support using the following table:
