5020 Unified Write Filter Memory Errors

Question

We're using Wyse 5020s (Model Dx0Q) with Windows 10 IoT Enterprise.  They were running just fine for a few months when several of our systems started getting Unified Write Filter memory errors.   We use these 5020s as point-of-sale systems.  We've only loaded Chrome and our credit card processing software and users RDP into servers that run our ERP software.  We ended up disabling the Windows Modules Installer, which appeared to alleviate the issue.  However, the same problem is starting to resurface on several of our systems again.  Recently, we've also excluded the Windows Defender folder in the Defender scans on a few systems, which seemed to delay the message a bit, but hasn't eliminated it.   Even at startup, the systems are already running at about 50-55% memory.  In the most recent case, the users of the system even turn it off every night.  Is anyone else having the same issue?  Does anyone have any suggestions?

Miyamash,

The issue is related to the way Chrome uses memory. Please review the attached document on how to troubleshoot this issue and how to resolve.

Thank you for the troubleshooting doc, Rmontalvo.  Before disabling the Windows Modules Installer we've even had instances where the filter filled up without launching any programs.  We'll try uninstalling Chrome on the next problematic system as a test.

I forgot to report back, but we haven't had the memory issue resurface after following RMontalvo's suggestion and removing Chrome.  Thank you for your assistance, RMontalvo!
