Uninstall Fonts through VBScript

I had to uninstall Helvetica and FoundersGrotesk fonts from all the machines in our environment. They had been initially been deployed through MSI a few years back when no one bothered to check if the uninstall of that MSI was actually removing the fonts. So now, since those MSI were not uninstalling the fonts from the machine, I decided to write a VBScript to delete those fonts. While I could find scripts to remove the fonts, but none of them actually helped me to remove the fonts.

I wanted a script which will delete any font starting with Helvetica or FoundersGrotesk from Windows\Fonts folder and from Registry to completely remove it.

You can use this script for other fonts, by replacing Helvetica with your font name and then change the length from 9 to the one of your fonts length. I have mentioned this in comments in the script where you need to change it.

This script will work for both 32-bit an 64-bit machines.

Citrix Receiver upgrade and double icon issue

I recently had to upgrade Citrix Receiver for one of my clients and I faced numerous issues during the install.
I had to enable SSO for Citrix Receiver and add a storefront URL so when the users launch Citrix Receiver they should be able to launch their apps store directly without going through login prompts and entering the url.

While Citrix Receiver can be installed with the following command:

CitrixReceiver.exe /silent /noreboot /includeSSON ENABLE_SSON=Yes ALLOWADDSTORE=N ALLOWSAVEPWD=S

And Store URL can be set in the ADM template of Citrix Receiver, however, you will need to uninstall the older version before you install the new one.

Other issues faced were for double icons which appeared on those users machines who had added an app store themselves in the previous version. When a new store was added through Group policy, it actually doubled the store and the icons.
The stores are created in the below registry key:
When I removed this for the user and infact for all the users, it left behind dead icons in Start Menu, Desktop and in Citrix Receiver console. Also due to these dead icons, then I faced issues for Citrix stealing focus from all other applications.

Citrix suggests to use Citrix uninstall utility, but that works only when a logged on user runs it as an administrator which is rare in our environments.

I wrote following script to install, delete dead icons and remove the HKCU keys for all users of Citrix which are left behind.
You will Need:
1) Citrix Receiver
2) Receiver Cleanup Utility
to be in the same install  folder as these scripts.

How to uninstall any version of Java

I wanted to uninstall Java from all the machines and install the latest one. There were sometimes multiple versions of Java which had to be removed. Some machines had both 32 bit and 64 bit Java versions. Here is the easiest batch script to uninstall any version of Java on the machine.
There were scripts available but they did not delete 64 bit versions of Java and some very old versions of Java. Hence I modified those scripts to meet my need.

set mycmd=reg query HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall /s /f *java* for /f " usebackq delims={} tokens=2" %%i IN (`%mycmd%`) do ( msiexec /uninstall {%%i} /passive )
set mycmd=reg query HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall /s /f *java* for /f " usebackq delims={} tokens=2" %%i IN (`%mycmd%`) do ( msiexec /uninstall {%%i} /passive )

VBScript to change the proxy settings if disconnected from VPN

When connected to VPN, user's IE proxy settings get changed and is forced by VPN.
Often the users might get disconnected from VPN while working from home and this does not revert back the proxy settings to the original one.
I have written a VBScript to change the proxy settings of the users. This script can be made a shortcut and then used.

objShell.RegWrite RegLocate,"","REG_SZ"
RegLocate = "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyEnable"
objShell.RegWrite RegLocate,"0","REG_DWORD"

'Enable AutoDetect in the proxy by calling this sub

MsgBox "Proxy is reset to AutoDetect"

'I do not want any proxy so I have disabled this, but if you want to set a proxy then you can use this.

Packaging Skype with Auto Update disabled

EDITED: I have edited this post on 30-Aug-2013 after some users comments that the given solution is not working. I have studied in depth the skype update process and created this solution for all. Please check below (Edited Section) for more information.

Recently while packaging Skype for enterprise version, I could not disable the Auto Updates and finally found a way to get rid of it.

You can get the latest version of Skype setup in MSI format from the following URL: or

There is no registry, file which can disable the Auto Update functionality of Skype. I searched in lots of forums and all said that it automatically prompts for update. So finally I decided to look in the MSI and find why and how it is doing it.

What I found was that Skype has an Updater.exe in the installation folder and it also creates a Skype Update service which points to this exe.
I just removed this service and updater.exe file from the skype msi package and it worked.
No need to do anything else. Just do this small part and you are done with removing the Auto Update in Skype.

I have been asked and told by a lot of users that this is not working so I am adding a further solution which will definitely work without a doubt. I have mass deployed this and it has worked fine. For all the users who were getting the pop ups, this has fixed it.

You need to create a dummy SetupSkype.exe file and a Skypefix.vbs as below and add it to your INSTALLDIR (C:\Program Files\Skype\Phone\) of the package.

dim filesys, oShell
Set filesys = CreateObject("Scripting.FileSystemObject")
Set oShell = CreateObject("WScript.Shell")

des1 = oShell.ExpandEnvironmentStrings ("%Temp%")
sup = oShell.ExpandEnvironmentStrings ("%ProgramFiles%")
windir = oShell.ExpandEnvironmentStrings ("%Windir%")

destfile1= des1 & "\SkypeSetup.exe"
sourcefile1= sup & "\Skype\Phone\SkypeSetup.exe"

'Copy files

If filesys.FileExists(sourcefile1) Then

 a= filesys.CopyFile (sourcefile1, destfile1,True)

End If

oShell.Run windir & "\System32\Icacls.exe " & destfile1 & " /deny Everyone:D"


After this you need to create an Active Setup registry key which will run this vbs file for every user who logs off and logs in. After this there will be no upgrade issue.

This script works on the fact that SkypeSetup.exe gets downloaded from internet to %temp% folder of user and when it is downloaded, it starts prompting up for upgrade. I have created this file before hand in %temp% folder or replace the already existing one with this dummy file and then put a deny restriction to all the users on this file. So now a file cannot be downloaded to %temp% folder because there is already a file which cannot be deleted/replaced. Hence no more upgrade prompts.
I have created this solution by deeper understanding of Skype setup and upgrade.

Hope this tip will be helpful to you and let me know if it still does not work.

How to clear App-V Cache

This has become my favorite site today because one of the issue which I was facing in App-V while testing was because the App-V cache was not getting cleared.
I used one of the method used here and it worked for me.
I want to share this link with all and want to bookmark it for myself for future reference.

In Summary, these are a few good options to start with:

First, get a list of all AppV applications:
sftmime query obj:app /short
Remove all applications from the cache:
sftmime.exe remove obj:app /global /complete
Remove a specific application from the cache:
sftmime.exe remove app:”applicationName” /complete

Hope your issues are solved with this as well.

App-V with Java/JRE/JDK

It is very critical to understand how to handle installation of Java related applications in App-V environment.
While some are of the view that the application should be installed along with Java in the same bubble while some say that the Java version installed on the base machine can be used.

Here is how you can do both of these in a proper way:

1) Java installed locally on the machine: If Java is locally installed on the machine and you capture the App-V application, then you will see a hard coded entry in the registry. This basically points the App-V application to look for Java in this local machine location. If you upgrade your Java version from say 1.6.21 to 1.6.24, then you do not need to worry, however, if you do a major upgrade from 1.6.21 to 1.7.xx then you need to upgrade your App-V Application as well. You need to maintain the software library for all these applications and then upgrade them as part of Java Upgrade in the organization.

2) Java is installed as local copy inside App-V bubble: Java can also be installed as a local copy with your App-V application. There can be various reasons for doing this:
 a) Application is compatible only with a certain version of Java
 b) Application uses a higher version which is not locally installed.
 c) If Software manager do not want to upgrade the application every time Java gets updated.

In these cases a private copy of Java can be captured with App-V. However, there is a procedure for achieving this.
These steps will be helpful in doing this:

Detection Method for MSU in Applications for SCCM 2012

In SCCM 2012 Applications you can have a detection method set for MSU with KB numbers.

You can use the Powershell or VBScript to do this. Here is an example of both.

Powershell Script:

get-hotfix | Where-Object {$_.HotFixID -match "KB981603"}


'Returns info if Windows 'KB981603'  in installed
' ----------------------------------------------------------'
Option Explicit

Dim objWMIService, strComputer
strComputer = "."

'Run the query
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" _
    & strComputer & "\root\cimv2")
Dim QFEs
Set QFEs = objWMIService.ExecQuery ("Select * from win32_QuickFixEngineering where HotFixID like 'KB981603'")
For Each QFE in QFEs
    Wscript.echo "Update KB981603 was installed by " & QFE.InstalledBy & " on " & QFE.InstalledOn
