In the realm of virtualization, VMware has established itself as a leading player, providing innovative solutions for businesses and individuals alike. One of the most sought-after resources for VMware users is the knowledge base (KB) article repository, which contains a vast collection of technical articles, troubleshooting guides, and best practices. In this article, we will focus on KBVMWare article 78708 and explore free solutions related to this topic.
As of December 3, 2019, Microsoft changed its driver signing policy to exclusively use the SHA-2 algorithm. Many legacy Windows 7 and Server 2008 R2 instances were originally installed with only SHA-1 signing support.
Backup Your Environment: Never modify your hypervisor configuration without a verified backup of your Virtual Machines (VMs) and host configuration.
Because this issue is so common, the critical information from KB 78708 has been widely quoted and mirrored across the internet by technical blogs, forums, and Q&A sites. A simple web search for a phrase from the article, such as "VMware tools upgrade fails on windows without sha-2 code signing support (78708)" , will bring up many results. Sites like Programmer Sought, CSDN, and Juejin often have complete reproductions of the article's content. kbvmware s article 78708 free
Administrators usually encounter one or more of the following indicators when running into the KB 78708 issue:
When attempting to install or upgrade VMware Tools on a Windows 7/2008 R2 VM, you may experience:
Before you begin, ensure your guest Windows 7 or Windows Server 2008 R2 system has Service Pack 1 (SP1) installed. You can check this by right-clicking on 'Computer' and selecting 'Properties'. In the realm of virtualization, VMware has established

Starting , Microsoft transitioned exclusively to the SHA-2 code-signing algorithm for all software updates and drivers. Because modern versions of VMware Tools are compiled and signed strictly using SHA-2, legacy Windows guest operating systems that lack built-in SHA-2 support cannot read or authenticate these new digital signatures. Consequently, Windows blocks the VMware driver installation as a security precaution, triggering an upgrade failure. The Solution Provided by KB 78708 As of December 3, 2019, Microsoft changed its
If your enterprise environment strictly prohibits modifying the legacy guest OS with new Windows updates, you cannot run modern versions of VMware Tools. Your alternative option is to freeze the VM on an older version of VMware Tools that still utilizes SHA-1 driver signatures. VMware tools fail to install on Windows 7 Guest | Fusion
The primary reason VMware Tools upgrades or fresh installations fail on legacy operating systems like and Windows Server 2008 R2 SP1 is a missing SHA-2 code signing support patch. Because newer VMware Tools versions (specifically 11.1.x and above) exclusively use SHA-2 digital signatures, unpatched systems fail driver signature verification, causing the setup to abort with generic driver installation errors.
Legacy systems like Windows 7 Service Pack 1 (SP1) and Windows Server 2008 R2 SP1 do not natively support SHA-2 code signing. Because VMware Tools 11.1.0 and subsequent versions are signed using this newer algorithm, the operating system rejects the drivers, leading to installation errors or failure to load drivers.
