VMware also notes that future driver packages will continue to be signed using SHA-2 as part of the evolving security landscape.
On December 3, 2019, Microsoft deprecated the legacy SHA-1 hashing algorithm for driver signing due to inherent security vulnerabilities, migrating entirely to the more secure .

Historically, older operating systems relied on the to verify digital signatures for hardware and software drivers. However, due to inherent security vulnerabilities in SHA-1, Microsoft deprecated its use.
Backup Your Environment: Never modify your hypervisor configuration without a verified backup of your Virtual Machines (VMs) and host configuration. VMware also notes that future driver packages will
addresses the failure of VMware Tools installation or upgrades on older Windows operating systems. As of December 3, 2019, Microsoft shifted to exclusively using the SHA-2 cryptographic hash algorithm for driver signing.

KBVMware Article 78708 is useful for several reasons:
VMware Tools installation failures on Windows 7 and Server 2008 R2, as detailed in KB 78708, result from missing SHA-2 code-signing support required for newer driver versions. Resolving these issues involves manually installing Microsoft patches KB4474419 and KB4490628 to enable SHA-2 support, followed by a system reboot and re-attempting the installation.
