VDI optimization script (part 1)

Car repairIn the summer of 2010 Erik wrote an article about “How to: Optimize guests for VMware View” in which he describes all sorts of changes he makes for a Windows XP or Windows 7 virtual desktop in a VDI environment. The changes that are suggested in the article are still valid, but after reading them I was wondering if there are new additions, specifically with Windows 8 now on the market. During my search I quickly came across a Visual Basic script that was released by Microsoft on their Technet site for optimization of a Windows 8 virtual desktop.

At the beginning of the script there is a disclaimer that you should have knowledge of the vb scripting language and that you should proceed with caution. Since the script is fairly long and a lot of changes are being made I decided to break the script down and put this in a table to give an overview of the services and settings being changed. As the title of the article indicates this is part 1 of the article, in part 2 I will try to explain the different pieces of the script in such a way that more people might understand what is happening inside the script.

While putting everything into a table I also looked if these changes could be made for a Windows 7 desktop too. The table is divided in several parts (and one bullet list) to provide some more overview to the whole.

Hopefully the tables provide you with an overview that can help determine which settings might be useful for your VDI environment. In the next part I can hopefully explain the script in some more detail so that you can use it yourself.

    Does it works for Windows 7 as well? If not, any equivalent script for Win7?

    • Sander

      As far as I can tell it should work for Windows 7 aswell, minus the parts that don’t have an X behind them. Later this week I hope to post some more indept view of the script so you can find the parts you need more easely.
