Weekly End User Computing roundup for 15-22 July 2026: NetScaler CVE-2026-8451 still exploited, a record Windows Patch Tuesday, Entra retiring SMS/voice MFA, XenServer 9 preview, Nutanix and vSphere deadlines, Intune E3/E5 changes and more.

A few weeks ago, I did a research with Leee Jeffries for GO‑EUC on NVMe memory tiering versus traditional swap in VMware ESXi. VMware ESXi Memory Management Reimagined: NVMe Tiering vs Traditional Swap | GO-EUC The article sparked some great discussions and there is an important caveat when it comes to vGPU desktops that I want to highlight. vGPU Desktops Always Need Full DRAM Here’s the thing that often trips people up: every VM with a vGPU requires all of its RAM to be rese

Measuring Real Latency — The Missing Piece in VDI Performance Latency isn’t just a number you pull from monitoring tools. It’s about the delay users feel, the gap between when they click and when something actually happens on their screen. In virtual desktop environments, traditional latency metrics (like server response times or network delays) only tell part of the story. Users interact with their device locally, so the real question is: how long does it take until their sc

You know, most VDI environments run like a well painted canvas. The default FSLogix GPO covers most users with smooth even strokes. They are happy users, their profiles load fast, and the picture looks just right. But then there are the VIPs, those special users with bold bright colors. The users with massive OST caches that need a bigger space, or the sales crew whose Teams data just keeps growing like a happy little forest. This is when the ObjectSpecific keys step in, like

Omnissa Intelligence has been in the stack for a while now. Most people knew it existed, but it often got ignored, to many day-to-day concerns like UEM, Horizon, or App Volumes. Intelligence always looked promising, but it felt like another dashboard with too many lines and not enough relevance. That... is changing. The Digital Employee Experience (DEX) side of Omnissa Intelligence has received serious attention. It is now mature enough to actually do something useful in r

On december 18, 2024, I had the honor to do a live webinar with Leee Jeffries. "Mastering the Multi-Layered EUC Environment: A Journey Through the Maze" We show how we test and validate the layers with Login VSI. Some of the technologies mentioned are Omnissa Horizon and Appvolumes, Liquit part of Recast Software, IGEL Technology and Microsoft EntraID Conditional Access... sounds like a challenge right!? In case you missed it, here is a link to the recording: Mastering the M

So… on December 19th of 2024, Omnissa released App Volumes 2412. One change I’m most thrilled about: MSI for Windows Endpoints AND and discovered: Physical Endpoint support! App Volumes now supports MSI-wrapped VHD packages, alongside traditional VHD and VMDK formats. This allows the App Volumes agent to operate independently within existing delivery infrastructures such as Workspace ONE UEM, Microsoft Intune, and Microsoft Configuration Manager. and with the parameters of th

Recently got involved in designing and building a new awesome blistering fast Omnissa Horizon environment for a hospital. This new environment is based on the latest Horizon ESB, DEM, AppVolumes, Windows 11 etc. And as many hospitals do, they use Imprivata OneSign. We ran into a bug. When logging in to the desktop (either Imprivata Client or Horizon client directly) we got confronted by the Imprivata GINA screen. Once again entering credentials and the desktop continues. Reco

A while ago I created a discission tree to explain/help customers and coworkers with a couple of the design choices possible with the FSLogix Office 365 and/or the Profile Containers. I thought to share this, hoping this will help others in their decision making! If you need any help, additional explanation, have any remarks or additions I should add, please let me know! First starting with some of the basics, if you don't need the basics just scroll down to use the chart! W

A while ago I wrote a cross reference blog with my buddy Henry Heres about integrating Citrix Gateway and VMware Workspace One Access. A respected customer read these blogs and tried integrating this in their environment but ran in to issues and called for some assistance. Unfortunately, the original scenario we blogged about did not work in this specific environment, so I had to find an alternative way. In this blog I will show you another option and how to configure this!

As you probably already know App-V was originally scheduled to end in January this year (2023). Recently Microsoft announced they pushed the EOL date to April 14th, 2026 so you have still have some air left. But you have to think about a new strategy to deliver the apps. A great alternative is VMware AppVolumes! Little is known you can also use this when you use Citrix Virtual Apps and Desktops. Even better you can use this with the new amazing AppVolumes on Demand feature!

Ran into a little bug yesterday while implementing VMware Horizon and Imprivata. Appliances rolled out, configured the site, policy's etc. etc. On the regular Windows endpoints this worked as expected. Login went fine, tabbed a badge, entering additional credentials if required by policy and the session would beautifully start, locking, roaming, smooth as silk.. Pushed the Imprivata agent to the Thin Clients (Dell Wyse based on Windows 10 IoT, although the brand does not matt

Recently I had a little challenge with an on Prem VMware Horizon VDI environment and the implementation with FSLogix Office and Profile Containers. Due to restrictions there was only one file server available based on Microsoft. In case of an outage the server is replicated to another datacenter but it would take a short time to be available. This and the fact of course the server needs Windows Patches with their respective reboots gave me a bit of a puzzle. Why? Well if an F

On a recent project I had to deploy multiple VMware UAG’s for external access. The UAGS are hosted at a cloud provider and the only access I had was the vCloud director. So no PowerShell deployment or the default OVA deployment trough vCenter. Unfortunately the deployment did not work, the backend team was not available at the time (bigger priorities and Ok fair enough Friday late in the afternoon) so no escape to a regular deployment and of course I gave myself a deadline fo

Last year I wrote a little blog about power consumptions and created a little dashboard to see if we can save some power. Link: Monitor Performance while reducing power usage/ C02 Emission ? Yes we can! (debruinonline.net) In the past many best practices preached: disable power management features! Policy to High Performance. No delay is acceptable! Electricity is cheap...but the world has changed. I noticed that when I talk about saving power 90% of the time the discussion i

A while ago me and my friend and colleague JP Ruitenbeek were “flown in” to investigate performance issues at a customer. We found multiple issues but in this one we focus on a specific one: “The After-reboot jobs.” The Start: Lately a lot of complaints received the IT department of this customer about performance, latencies and login issues. The users were simply losing trust in the environment. Sum up some of the complaints: · Login times very high · Slown

Regularly I get questions about the flow when a user is getting external access and the relationship between the Unified Access Gateways, load balancers and the Connection servers. Especially because we sometimes need to deviate from the VMware Reference Architecture. This deviation could generate an error on the connection server. Most engineers cannot stand an error... they just want to eliminate it! (And of course, I praise them for it!) NuBut like many things in life, som

A while ago I got asked by a customer how they can auto turn off the monitor when they move away from the workstation. These workstations are located on an Intensive Care unit so when they need to access these machines at night, they want the monitors "on time" limited to a minimum to not wake up the patient too much. First thought: Manually turning off these monitors with the power button? (Smile and wave. No, we can do better!) Second thought: Power settings and the monitor

Buffer Overflow: [a] condition at an interface under which more input can be placed into a buffer or data holding area than the capacity allocated, With al little creativity and bending we also see this in a VDI environment, I name this a User Overflow: [a] condition at an environment under which more users try to be placed into a pool than the capacity allocated, Of course with VMware Horizon you can make the pools dynamic in size but you will be limited by the available har

Last week I was exposing my VMware Horizon environment externally. Of course I wanted the single sign on experience. So enrolled the Workspace One Access tennant, deployed the sync server.. configured directory sync, authentication rules, next Virtual Apps etc . On the connector SAML to required, configured SAML authenticator to Access, connector in Workspace One mode, deployed enrollment server, created TrueSSO template, configured TrueSSO, deployed UAGS etc etc and let the
