Windows 10 Build 19536 Causes VMWare Compatibility Issues For Many Users — Here’s How To Fix It

Microsoft rolled out Windows 10 Insider Preview Build 19536 for Fast Ring Insiders this week. The update brings many important changes, new features and quality fixes for Windows 10 users.

Speaking of the new features, the update brings optional driver updates in the Windows Update section and a new Family group setup option. In addition, Microsoft has also rolled out some big changes for Windows 10 Your Phone app.

However, some users who tried to install the latest build experienced some problems. The installation of Windows 10 Insider Preview 19536 fails on VMWare VMs with the following error:

“Installation Failure: Windows failed to install the following update with error 0xC1900101. Windows 10 Insider Preview 19536.1000 (rs_prerelease).”

 

As of now, there is no official word from Microsoft, but some people believe that it is a VMware compatibility error. Windows Insiders encountered a similar issue in the previous builds as well. Here is how one user explained on Microsoft Answers forum:

“This is only a VMware compatibility error, as has been encountered with a few prior Insider builds. Hyper-V VMs see SCSI drives without issue running build 19536. SCSI support is standard, so using SATA is just a temporary workaround until VMware & Microsoft sort things out.”

It seems to be a major bug that was apparently overlooked by Microsoft during the internal testing phase. If you are on the same boat, a trick allows you to install the latest Windows 10 20H2 Build.

Some clever Windows Insiders found a workaround to fix this issue. According to the forum reports, they managed to install the update by adding a SATA drive to the VMware VM. However, the installation process took almost an hour for some of them.

Follow the steps mentioned below to resolve this issue:

  1. First, stop your virtual machine.
  2. Navigate to the left pane and click Edit virtual machine settings.
  3. Click the Add button at the bottom of the Virtual Machine Settings page.
  4. A new window Add Hardware Wizard will open on your screen.
  5. Select New Hard Disk > SATA and click on Use an existing virtual machine.
