Use the System Restore tool to restore the affected computers back to a point before the problematic updates. To forestall issues with problematic updates, one needs to install and configure the Windows Server Update Services (WSUS) Server role.
Explanation:
Windows Update creates a restore point prior to applying any updates and this makes it easier to rollback any problematic updates using the aptly named System Restore utility. System Restore can be launched either from within Windows or during startup depending on whether the computer can be booted or not.
One solution to preventing this kind of problem is the implementation of a Windows Server role, the Windows Server Update Services (WSUS), which helps administrators to safely manage Windows Update for clients within its network. WSUS allows administrators to test updates for issues and approve them before they are available for deployment to clients.
