What is Vsphere Update Manager?
VMware Update Manager is a utility that oversees the installation of updates for existing installations of VMware ESX Server and guest operating systems. Update Manager tracks vulnerabilities within the virtual infrastructure and automatically applies user-defined patches to eliminate those vulnerabilities.

2. Select Plug-ins > Manage Plug-ins.
3.In the Plug-in Manager window, click Download and install for the VMware vSphere Update Manager extension.
4.Select a language for the installer and click OK.
5.Review the Welcome page and click Next.

9.Complete the Update Manager Client installation, and click Finish.
The status for the Update Manager extension is displayed as Enabled.
10. Click Ignore if a security warning appears.
The security warning appears when the vSphere client detects a certificate that is not added in the Trusted Root Certification Authorities store. This is usually the case with the self-signed certificate used by ESX/ESXi hosts by default. For highly secure environments, you must set up a trusted third-party certificate later.
11. Click Close to close the Plug-in Manager window.
The icon for the Update Manager plug-in is displayed on the vSphere Client Home page under Solutions and Applications.
