Issue

Right click > New Windows context menu doesn’t display New Word Document option. Repairing MS Office installation doesn’t fix the issue.

Resolution

• Create a black Microsoft word .docx file with name WORD12.docx and it copy to C:\Program Files (x86)\Microsoft Office\root\vfs\Windows\SHELLNEW folder
  
• Open Registry Editor (regedit.exe) and navigate to HKEY_CLASSES_ROOT\.docx
  • Double click on Default entry and change its value to Word.Document.12
    
  • Inside .docx key create key Word.Document.12
  • Inside Word.Document.12 key create another key called ShellNew
  • Inside ShellNew create String type entry with name FileName and value C:\Program Files (x86)\Microsoft Office\Root\VFS\Windows\ShellNew\WORD12.docx
    

That should be it, New Word Document should be back in the context menu.
