VMware Tools does not remove SYNC driver

Products

• VMware vSphere ESXi

Issue/Introduction

Symptoms:

• VMware Tools 4.1 and newer does not automatically uninstall the SYNC driver.
• Upgrading VMware Tools and specifying SYNC removal by using /s /v "/qn ADDLOCAL=ALL REMOVE=Sync REBOOT=ReallySuppress" does not remove the SYNC driver.

Environment

VMware vSphere ESXi 5.1

Resolution

The sync driver is only required for legacy versions of Windows, such as Windows XP and Windows 2000, which do not include the Microsoft VSS service.

When upgrading pre-4.1 versions of VMware Tools, it allows you to uninstall the SYNC driver. However, because SYNC functionality is not necessary in any guest OS that has the VSS service, the VMware Tools installer no longer offers the option to uninstall the SYNC driver.

To disable the SYNC drivers:

1. In the Windows Device Manager, click View > Show hidden devices.
2. Expand Non-Plug and Play Drivers.
3. Right-click Sync Driver and click Disable.
4. Click Yes twice to disable the device and restart the computer.
