For home users:

If you still decide to download Office 365 in RAR format, make sure to follow these precautions:

Download and install directly using Microsoft's official setup tool.

| Risk Category | Description | |---------------|-------------| | | RAR files are common vectors for viruses, trojans, keyloggers, and ransomware. Many “cracked Office” RARs contain password-stealing malware. | | False Positives / Broken Software | Files may be incomplete, corrupted, or outdated. Even if extracted, the software may fail to install or run. | | Legal Liability | Downloading unlicensed Microsoft software violates copyright law. You risk fines or legal action from Microsoft or local authorities. | | Lack of Updates | Pirated copies cannot access official security updates, leaving your system vulnerable to exploits. | | Activation Fraud | Many RARs include “activators” (KMS, patches) that modify system files, create backdoors, or inject adware. | | Data Theft | Malicious actors can embed scripts that harvest personal documents, browser credentials, and email data. |

: You can access web-based versions of Word, Excel, and PowerPoint for free by signing in at Microsoft365.com with a standard Microsoft account.

: Locate the "Download for Windows" button to save the setup file directly from Microsoft Support .

: If you need to install without a constant internet connection, Microsoft provides an official offline installer tool which is much safer than third-party archives.
