Update: Not sure if this was recent but you must now remove the (x86) out of the Program Files path (maybe they made the app x64 now?)

Here's a script I made that works really well. Of course you can tailor it for a GPO but standalone, it works wonders.

The gist is.. it will check if Dell Command Update is installed and if it is, it will run it and install all available updates. If it's not installed, it will look for the Dell Command Update msi and silently install it and then run it silently. If it cannot find the msi automatically, it will prompt you with an explorer GUI to browse to the .msi and silently install/run it.

Esentially.. a single click to do all Dell updates. It's also turning off Dell automatic update (handy for enterprise/small business) but you can delete/comment that out. In order to get the .msi you can run the Dell Command Update tool and in the middle of it running, you can find it in the Windows temp directory and copy it out of their and put it on a network share or USB stick for mass deployment.

Hi Another Poor Slob: See the section titled 'Update Settings' in the Dell Command | Update Version 4.x User's Guide. Is there a check box at Settings | Update Settings | Automatically Check for Updates | Check For Updates that you can disable to stop automatic background updating? I use Dell Update for Windows Universal v4.7.1 on my Inspiron 5584, which cannot run automatic checks for updates. However, the update setting described for Dell Command | Update v4.7.1 in that user guide sounds similar to the setting I have in SupportAssist v3.13.0.126 at Options (gear icon) | Settings | Automate Scans and Optimizations (see image below). -------------64-bit Win 10 Pro v22H2 build 19045.2486 * Firefox v109.0.0 * Microsoft Defender v4.18.2211.5-1.1.19900.2 * Malwarebytes Premium v4.5.20.230-1.0.1868 * Macrium Reflect Free v8.0.7279 * SupportAssist v3.13.0.126 * Dell Update for Windows Universal v4.7.1 * Inspiron 5583/5584 BIOS v1.21.0Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620
