Windows 7 Patch Tuesday Update Breaking Access To SMBv2 Shares

Microsoft has rolled out a handful updates for almost all valid
versions of Windows. These updates are part of the Patch Tuesday. There are
always certain known issues with OS updates. Even though Microsoft strictly scrutinizes
all its patches and updates, there are still some notorious updates that bypass
the scrutiny. The Patch Tuesday update for Windows 10 is a security update to
Windows 7 and Windows Server 2008 R2 with Service pack 1. The update is making
SMBv2 shares inaccessible once it is installed on the host.

The update KB4480968 has also been accompanied with similar
bugs. For example, remote desktop access failure is one of the disappointing bugs
that have followed the patch. These bugs are refraining users. Whose accounts
are under Administrator tag, to access remote desktop. The main Administrator
account is also affected. This error is not poking everyone though, but many
users reported about this.

If you want to get rid of this mess, the easiest solution is to roll back to the initial version by uninstalling the update. You can also deal with the issue by tweaking the registry files. Since, this involves a certain risk of getting your system crashed down, always keep a data backup ready. The same issues have been discussed and dealt with at German forums at

Command Prompt with administrator privileges and type the following command on
your host Windows device:

add HKLMSOFTWAREMicrosoftWindowsCurrentVersionPoliciessystem /v
LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f

That’s all. Microsoft is expected to release a fix
very soon.
