Windows 7 Registry Optimizations for Virtual Desktops


In another blog, I discussed Windows 7 services that you might wish to disable when going down the path of desktop virtualization. In this article, I’m now focusing on registry modification you will want to make to optimize Windows 7 for virtual desktops. I’ve broken it down into Recommended configurations, Standard Mode configurations (for Provisioning services), and Optional configurations.

As I learn more from upcoming Windows 7 implementations, I’ll be updating the following tables, so it might be worthwhile to stay updated with RSS or subscribe via Email. Now, for the good stuff… Continue reading “Windows 7 Registry Optimizations for Virtual Desktops”

Protection From Anti-Virus


Protection from antivirus.  Are you wondering if you read that correctly?  Yes, it is correct.  Odd isn’t it?  Anti-virus is there to protect us, but we also need to be protected from antivirus. Antivirus solutions are critical, even in a virtual desktop environment. Many people believe that because a hosted VM-based virtual desktop image is created from a real-only image that they are immune from virus.  That is only partially true.  When you reboot, the virus goes away because the changes to the base image are destroyed (including the virus), but what about that time period between getting infected and the next reboot? Those few hours are dangerous. Continue reading “Protection From Anti-Virus”

Dear Architect, is my write cache estimate correct?


The latest question into the Ask the Architect mailbag comes from Andy.  Andy is creating a Provisioning services design for an environment based on Windows Server 2008, with the write cache stored on a NetApp share.  Andy’s question is if the write cache estimates are correct.  Basically, Andy is estimating 650 MB write cache per virtual desktop.  He achieves this by taking the assigned RAM and multiplying it by 25%. First, using Windows 2008 is great for Provisioning services as this provides the largest system cache for the vDisk, which will speed up delivery as local disk reads are not … Continue reading Dear Architect, is my write cache estimate correct?

Clash of the Titans: Users, iPads and IT


The iPad was released, and people were happy. People brought the iPad to work, and users were excited. Users connected the iPad to the corporate environment and IT got scared. If you went to the Apple store and did a demo of the iPad, you might have noticed the installed Citrix Receiver (honestly, did anyone actually demo these things before buying? I bet most of us just bought it without playing around with it). But, let’s say you did demo and you selected the Receiver, what would you have seen? Windows Applications. Yes, Windows Applications on the iPad.  I admit, … Continue reading Clash of the Titans: Users, iPads and IT
