Answer:
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.

Explanation:
I've written a paragraph before. I should know!
<span>Not a valid IPv6 address
A valid IPv6 address consist of 8 groups of 4 hexadecimal numbers separated by colons ":". But that can make for a rather long address of 39 characters. So you're allowed to abbreviate an IPv6 address by getting rid of superfluous zeros. The superfluous zeros are leading zeros in each group of 4 digits, but you have to leave at least one digit in each group. The final elimination of 1 or more groups of all zeros is to use a double colon "::" to replace one or more groups of all zeros. But you can only do that once. Otherwise, it results in an ambiguous IP address. For the example of 2001:1d5::30a::1, there are two such omissions, meaning that the address can be any of
2001:1d5:0:30a:0:0:0:1
2001:1d5:0:0:30a:0:0:1
2001:1d5:0:0:0:30a:0:1
And since you can't determine which it is, it's not a valid IP address.</span>
