How to Clear Recent Project list or File list from Visual Studio .Net Start Page

Close Visual Studio (if its open)

    GOTO > Start > Run > RegEdit

    GOTO > HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\\ProjectMRUList
    remove unnecessary items from list.

    Similarly repeat the steps for FileMRuList
    GOTO > HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\\FileMRUList
    remove unnecessary items from list.

    To Clear the Find and Replace List
    GOTO > HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\\Find
    remove unnecessary items from list.

Another Simple way is,
    Create one Text file "Clear.txt" and add below contents in it

    Windows Registry Editor Version 5.00

    [-HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\ProjectMRUList]
    [HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\ProjectMRUList]

    Save and Close the file and rename is as "Clear.reg"; that is Registry file. Double Click to Run the file, this will clear the "Recent Project List" on your Visual Studio 2005 Startup Page. You can add entries for "Recent File List" and "Find and Replace List" in this same .reg file.
