Remove recent projects from Visual Studio Start Page
To remove the projects from the list, follow these steps:
1.Close Visual Studio if it is running.
2.Start the Registry Editor (run regedit).
3.Navigate to this registry key:
4.Then delete the key that has the project you do not want to keep in the list.
keep in mind is that the list only lists consecutive items starting File1. So if in the above list I deleted File6, then only projects corresponding to File1 to File5 will be displayed in the recent project list. File7 and above will not be displayed. If in case you like File7 and above to be displayed, you will need to rename one of the keys so that they form a consecutive numbered list.
