I had a problem on my 8940 the required me to reinstall W11 (or W10, forgot) using the Windows Media Install tool that installed Windows but not the Dell features. You CAN D/L SA from [URL]  and install it. I do HAVE it working, but the Scheduling DOES NOT. I have to run it manually when I 'think about it'. You should be able to remove SA via the Control Panel Programs and Features and then reinstall it and see if that fixes it?
Hello, I've noticed that the Dell Support Assist App does not appear to be working.  I am using Windows 10 Pro (ver. 21H2, build 19044.1469).  I try to run it weekly, but it hasn't automatically detected any updates in several months.  I have found the website doesn't work either when I log in to the support page and have it check for updates automatically.  I can see updates to my system manually and have gotten emails from Dell regarding updates. Are others having problems too?  Is there a way to refresh the Dell Support Assist App?  What do I need to uninstall and reinstall? Thank you.
