The Case of the Ever-Expanding, Dynamically-Expanding VHD

I recently had an issue where I encountered something quite bizarre. In an effort to reduce size on disk of dynamically expanding virtual hard disks (VHDs) I found myself feeling like I needed to take medication. After sysprepping an operating system image on the disk, the current file consumption on the disk was approximately 12…

MED-V: More Detail on Full-Screen vs. Seamless Mode

I recently had a customer inquire further as to how the mechanics differ between all of the application modes in MED-V. I would have thought this far into the life cycle of MED-V that I had gone into enough detail on the subject. Turns out, while the article I wrote on TechNet a couple of years…

App-V 5: Further Dissection of the App-V Error Code Format

I recently just returned from the Microsoft Global MVP Summit where I got to spend some time with the App-V MVPs. We received a lot of good feedback and I got to see some great presentations (as well as do a little bloviating of my own.) I received specific feedback encouraging me to write more…

App-V 5: Useful Stuff for the App-V Professional (I hope!)

So I’ve been receiving a lot of feedback on ways to enhance  App-V toolkits for customers and their in-house troubleshooting. I’ve received usually two kinds of feedback on previous articles such as http://blogs.technet.com/b/gladiatormsft/archive/2013/11/13/app-v-on-operational-troubleshooting-of-the-v5-client.aspxand http://blogs.technet.com/b/gladiatormsft/archive/2013/04/24/app-v-5-0-launching-native-local-processes-within-the-virtual-environment.aspx – 1) This is great! Can I have more?” and 2) “It’s about @*#&% time!Can I have more? Do we have…

Here’s a Short Blog with a very Important Message (T-MINUS LESS THAN 6 MONTHS)

Early last year I wrote a blog specifying how MED-V does NOT affect the Windows XP EOL Support issue: http://blogs.technet.com/b/gladiatormsft/archive/2012/07/30/how-med-v-affects-windows-xp-end-of-life-support-policy-it-doesn-t.aspx  Little did I know how widely pulicized this would be (re: quoted in The Register and others – http://www.theregister.co.uk/2012/08/01/windows_xp_medv_no_go/) Today’s a good reminder for all that we are now within six months. If you are…

App-V: On Operational Troubleshooting of the V5 Client

 Update 12/6/2014: The App-V 5 logs have been consolidated and are organized differently as of App-V 5 SP3 – but the event and event formats are still the same. Please read more about it here: http://technet.microsoft.com/en-us/library/dn858700.aspx#BKMK_event_logs_moved Whenever I am doing customer engagements, I find it always valuable to ensure that the customer has a plan…

App-V: On Virtual Services in App-V 5.0

On the subject of services, it is probably worth mentioning some of the changes with how App-V handles virtual services in V5. First and foremost, you may have noticed there is no separate virtual service agent service running for the V5 client. You have probably also noticed that virtual services are not managed or modified…

App-V: On COM+

Throughout the history of App-V and Softgrid, you have likely read from many sources that COM+ cannot be virtualized. Many tools, including the App-V sequencer, contain detection logic that will also notify you of the presence of COM+ components when you are attempting to sequence an application. COM+ evolved from DCOM (Distributed Component Object Model)…

App-V: On Named Kernel Object Virtualization (a.k.a. the VObjects Subsystem)

Virtual Objects: You have also possibly heard this referred to as virtual eventing. You have seen references to this in the context of troubleshooting. You may have possibly used this as a workaround when troubleshooting in 4.x: Add an asterisk wildcard in the following registry path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SoftGrid\4.5\SystemGuard\ObjExclusions Before you ever do the above again, please…
