I wish people would read a person's question and if they don't understand it, either:
1. don't post

2. ask for clarification
I, too, would like an answer to AMukesh's question.
richc46's answer is not what we are looking for. His link simply shows the 2 most common ways in Windows 7 to deal with jump lists:
1. Right click an individual item and delete it
2. Uncheck, apply and re-check "Store and Display Recently Opened Items in the Start menu and the taskbar"
The first way deletes one item.
The second method deletes
all items in
every jump list.
What we are looking for is a way to delete
all items in a
single jump list.
For example, I want to clear my jump list for Windows Media Player, but NOT for Microsoft Word. Right now, the only way to do it is to right click each item in the Windows Media Player jump list and click delete - very tedious and annoying.
