Note: I’ve included a disclaimer about software piracy and security risks, as Office 2007 is no longer supported by Microsoft and portable “cracked” versions are often unsafe. You’ve seen the links. “Office 2007 Portable – Download from Google Drive (No install, free).” They pop up on forums, Reddit threads, and sketchy software blogs.
