Where can download Rollup 5 for Forefront TMG 2010 SP2?

Hello 轶霖 应, I'm Henry. I’d like to share some thoughts on your issue. While I’m unable to reply in your native language, I’ve translated the content to better understand your situation.

It is understandable that you are looking for hotfix KB2954173 (Rollup 5) for Forefront TMG 2010 SP2, especially when maintaining a legacy system. However, I cannot send you this patch, and the public download is no longer available for critical, evidence-based reasons.

The primary reason is that Microsoft Forefront TMG 2010 is a discontinued product and has reached its end-of-life, meaning all support and official downloads have been terminated.

1. Product Discontinuation: Microsoft announced the discontinuation of the Forefront TMG product line on September 12, 2012. The product was no longer available for purchase after December 1, 2012.[Forefront TMG 2010 End of Life Statement]
2. End of Support Lifecycle: Microsoft has a formal lifecycle policy for its products. For Forefront TMG 2010:
   • Mainstream Support Ended: April 14, 2015.
   • Extended Support Ended: April 14, 2020. As of this date, the product is completely unsupported. Microsoft no longer provides any patches, security updates, or downloads for it.[Microsoft Forefront Threat Management Gateway 2010]
3. Removal of Download Links: As part of the end-of-life process, Microsoft removes the official download pages for the software and its related patches. While the support article for Rollup 5 (KB2954173) still exists, it no longer provides a download link. The article states, "If the hotfix is available for download, there is a 'Hotfix download available' section at the top of this Knowledge Base article. If this section does not appear, submit a request to Microsoft Customer Service and Support to obtain the hotfix." Since the product is now unsupported, submitting a request to Microsoft Support will no longer yield the hotfix.

It is crucial that you do not attempt to acquire this hotfix from unofficial third-party websites, forums, or individuals. Obtaining software from unverified sources carries significant security risks, including:

• Malware: The file could be bundled with viruses, ransomware, or spyware.
• Tampering: The patch itself could be altered with malicious code, creating a backdoor into your network.
• Instability: The file could be corrupted or an incorrect version, causing system instability or crashes.

Because Forefront TMG 2010 has not received security updates for many years, it is already inherently insecure. Running an unsupported firewall is a major risk to your network's security. The recommended action is to migrate from the obsolete TMG 2010 to a modern, actively supported firewall and secure web gateway solution.
