VMware supports the installation of minor update releases on an operating system as an upgrade in a virtual machine, such as Windows 7 to Windows 7 SP1 or RHEL 6.0 to RHEL 6.1, provided:
- The minor update release is supported by the operating system vendor on VMware products.
- The minor update release is installed as per instructions from the operating system vendor.

Caution: VMware does not support in-place upgrade of the OS where a VMware component/application (Example: vCenter Server Windows) installed (Except VMware Tools).
That means VMware supports OS in-place update/upgrade for VMs with OS(s) that have VMware Tools installed.
"If the OS vendor has narrowed down problem to be specific to VMware software, then VMware can provide assistance."
