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 )
