Hi @lmacri thank you for keeping in touch. 

My Windows Reliability Monitor and Event Viewer have NOT been logging USBIEUpdate (UsbUpdate.exe) errors. 

Windows Reliability Monitor, has many Background Task Host Critical events, which keep complaining about Microsoft.WindowsFeedbackHub_1.2106.1801.0_x64__8wekyb3d8bbwe. 

If SupportAssist installation attempted, there is only a Warning event that reports installation failed 1603.

Hi crimsom:

Any chance you're being offered a newer v3.11.3.63 .msi installer today?

I'm not sure what's going on, but Dell employee Chris M posted today on page 15 of LittleMaui's Inspiron 3891, Event Viewer Error - Usbupdate.exe Fails that "We have been told the fix will be an automated update push through SupportAssist". Gee580 reported <here> in that same thread that their SupportAssist v3.10.4.18 updated to v3.11.3.63 (after one failed attempt), but when I launch my own SupportAssist for Home PCs on my Inspiron 5584 it still reports that v3.10.4.18 is the latest version. Perhaps SupportAssist v3.11.3.63 is only being pushed out to higher-end Alienware / XPS / Latitude / OptiPlex models.

Hi crimsom:

Also, do you know where those Background Task Host errors for C:\Windows\System32.BakgroundTaskHost.exe are located in your Event Viewer? Those errors are different from the Dell SupportAssist update/installation warnings being logged in your Reliability Monitor that you showed <here> in you 28-May-2022 post, so it's hard to know if they're related in any way to your SupportAssist installation failures.

The problem details for those those critical Background Task Host errors (Problem Event Name = MoBX; Faulting Module = KERNELBASE.dll) mention the Microsoft AAD Broker Plugin, which might be logging events at Event Viewer | Application and Services Log | Microsoft | Windows | AAD | Operational. My own Event Viewer shows that I haven't had anything logged in that area of my Event Viewer since the last time I was running tests on my system after logging in with a local Windows user account (i.e., not a Microsoft account) with Standard (non-Administrator) permissions.

Have you run sfc /scannow or any of the DISM commands like Dism /Online /Cleanup-Image /CheckHealth from an elevated command prompt (see the ghacks.net article Use DISM to Fix Issues SFC Can't) just to make sure you don't have any corrupted Windows system files?

Hi crimsom:

Thanks for the update.

Just out of curiosity, do you recall where that DellInstrumentation.sys driver was located? I did a quick check and couldn't find it in the C:\Program Files\Dell or C:\Windows\System32 folders of my Inspiron 5584.

Hi @lmacri thank you for sharing request. 

The 17 R5 DellInstrumentation.sys driver is located at C:\Windows\System32\drivers. 

Having renamed the problematic 35KB system file DellInstrumentation.sys.old, at Restart, Windows automatically created a new 37KB DellInstrumentation.sys driver. 

Despite Programs and Features saying Dell SupportAssist Version: 3.11.3.63 was installed, 17 R5 Diagnostics said that SupportAssist was not installed. Having undertaken the renamed DellInstrumentation.sys fix, the SupportAssist Repair option was the only way to get SupportAssist to install and appear in the Start Menu (Windows). Very pleased that the Dell SupportAssist application has been reinstated, so that it can be used by other Dell applications. 

Repair SupportAssist

Hi crimsom:

Just an FYI that I can't find that dellinstrumentation.sys driver on my Inspiron 5584 / SupportAssist v3.10.4.18 laptop in C:\Windows\System32\drivers. That problematic driver might be specific to Alienware models like your 17 R5 [e.g., the Alienware Command Center (AWCC) and/or Alienware OC Controls application] or even the new Dell SupportAssist v3.11.x release itself.

As of today, my SupportAssist v3.10.4.18 is still reporting that v3.10.4.18 is the latest available version for my Inspiron 5584, and there's still no release notes or user guides posted for SupportAssist v3.11.x at https://www.dell.com/support/home/en-ca/product-support/product/dell-supportassist-pcs-tablets/docs.

Hi @lmacri thank you for sharing your FYI message. 

The 17 R5 C:\Windows\System32\drivers folder has 503 items. The following image shows my changes to the dellinstrumentation.sys driver. 

The behaviour of 17 R5 Diagnostics with Dell SupportAssist Version: 3.11.3.63, gives very different visual graphic tests and result tabulation. 

What I do not understand is why the new SupportAssist 3.11.3.63 files are installed where the installation process cannot find them, and has the wrong msi file name. So there was a lot of research and a small number of changes to file names, to get SupportAssist Repair to work, because SupportAssist Install does not work. Dell Quality Assurance on this SupportAssist version update is poor. 

SupportAssist Version: 3.11.4.29 arrives, but full installation fails. Have to repair this version update to get full installation. 

Seems the issue is related to a outdated NET 5.0: https://www.dell.com/community/SupportAssist-for-PCs/Dell-Support-Assist-Fails-to-install/m-p/8208504#M92914 

Dell needs to fix this ASAP... 

Same problem here on both my systems. The installation starts but comes up with the error that the installation was unable to complete the installation. Restart the PC dosent help. So the update is failing. I guess @crimsom that we have to wait for Dell to send out a automatic fix so the installation will complete successful? Seen several post on the same problem today.
