Release January 8, 2019—KB4480970 (Monthly Rollup) for Windows 7 Service Pack 1 and Windows Server 2008 R2 Service Pack 1 has Known issues that give you BIG problem.

Out of all the problem, i will cover two of them:

SMBv2 could not be connected anymore after installing this patch. The admins with networks using SMBv2 shares are reporting the bug.

2. Network interface controller may stop working

Symptom from Microsoft

After you apply this update, the network interface controller may stop working on some client software configurations. This occurs because of an issue related to a missing file, oem.inf. The exact problematic configurations are currently unknown.

Windows Explorer crash when using “Send To – Mail recipient”

Got an problem with the context menu option:  “Send To – Mail recipient”. Windows explorer crash and reload. 

The problem is observed on Windows 2016 and Windows 10 (several Builds) in combination with Office365 and Click-To-Run.

The issue is not any news,  it should really be fixed soon in future release, please Microsoft.

Problem happens when a user click on the option showed.

Solution

Add the following registry value to all terminalserver/clients to fix the problem. It solved for users after logoff and on again.

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ClickToRun\OverRide]
“AllowJitvInAppvVirtualizedProcess”=dword:00000001

Workspace App dont work with Safari 12

After upgraded to Safari 12, Citrix Workspace App and Citrix Receiver do not start *.ica files any more.

To correct this problem, you need to change the web.config on all Storefront servers.

Solution:

For StoreFront deployments, modify web.config under the Receiver for Web (RfWeb) site (typically C:\inetpub\wwwroot\Citrix\StoreWeb) to activate the Citrix Receiver Launcher / Citrix Workspace App Launcher for Safari 12 and later.

1. Open web.config using your preferred text editor and locate the line : <protocolHandler enabled=”true” platforms=”(Macintosh|Windows NT).*((Firefox/((5[2-9]|[6789][0-9])|\d\d\d))|(Chrome/((4[2-9]|[56789][0-9])|\d\d\d)))” skipDoubleHopCheckWhenDisabled=”false” />

2. The value of the platforms attribute is a regular expression specifying the browsers that Citrix Receiver Launcher is used for client detection and HDX launches. Change the regular expression to:

“(Macintosh|Windows NT).*((Firefox/((5[2-9]|[6789][0-9])|\d\d\d))|(Chrome/((4[2-9]|[56789][0-9])|\d\d\d)))|Macintosh.*Version/(1[2-9]|[2-9][0-9]).*Safari/“

3. This will add Safari 12 and later to the list of browsers that Citrix Receiver Launcher will be used.
