A: No. Office requires registry entries and system files. "Portable" versions of Office 2010 are usually malware wrappers.
Let’s be honest: Microsoft Office 2010 was a golden era. It introduced the ribbon interface (which users had finally accepted), offered blazing speed compared to later bloated versions, and didn't rely on a subscription model like Microsoft 365.
A: Worse than direct zip sites. Torrents of Office 2010 currently have a 95% malware rate per security firm Sophos. The "top seeded" torrent is intentionally seeded by botnets to infect you. Conclusion The search for a "microsoft office 2010 free download zip file top" is a journey to a destination that no longer exists safely. The software is dead. The links are traps. Your desire to save money is understandable, but the cost of identity theft, ransomware, or a botnet infection is far higher than the $0 you save.
