If your ‘Recent documents’ section of the WordPad has gotten too big, you might be wanting to clear it out a bit. The process is tricky, but bear with me and follow these steps:
Open registry editor via Start Menu by typing in ‘Reg edit’ in the search bar.
Copy and paste this line into the Registry editor:
Computer\\HKEY_CURRENT_USER\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Applets\\Wordpad\\Recent File List
Delete the documents you don’t want to see anymore.
