VMware Horizon – Windows 10 Day 2 Maintenance

Release date: July 29th 2020

Welcome to my VMware Horizon series. As Microsoft releases updates and security-patches on a monthly basis, we also have to update/patch the template-vm on a monthly basis. I will also check and patch other software I have installed at this time. As I used the VMware OS Optimization Tool when creating the template vm, Windows Update was disabled during optimization. I will have to re-enable Windows Update, patch the OS, re-run OSOT, take a new snapshot and roll out this to the desktop pool.

The first thing to do is to power up the template-vm and open VMware Remote Console


Once Windows is up and running, I re-enable Windows Update by running the following commands in an administrative command prompt:

REG DELETE HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\WindowsUpdate /f
SC CONFIG wuauserv start= demand
SC START wuauserv
usoclient StartScan


Windows Update can also be re-enabled by using the new Update-Tab inside VMware OSOT


The Windows Updates now starts downloading and installing


Once all updates are downloaded and installed, I restart Windows when prompted


Once Windows has rebooted, I launch VMware OSOT and re-run optimization with a reboot afterwards


After the reboot, I re-launch VMware OSOT and run the Finalize procedure. Once finished, I shutdown the template-vm.


Next, I delete the existing snapshot the desktop pool is based upon and create a new one. In a production environment, it would be preferable to disable provisioning on the desktop pool before deleting the snapshot, but as this is a lab with very little consequences, I will just do it like this in this session.


I push out the new snapshot to my desktop pool in the VMware Horizon Administrator Console


I can now monitor the progress of the Push-operation in Horizon Admin Console and vSphere.


When the Push-operation is complete, the State changes to “Published” and the virtual desktops have the status “Available”


With that the maintenance is complete for this month, to be repeated next month.
