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:
HKCU\Software\Citrix\Dazzle
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.
