Windows 10 Update Fails ... and a fix!
I ran into a pretty strange issue today. A windows 10 machine on build 1803 refused to update to 1903. I tried running the Windows Update Troubleshooter, I tried deleting the update cache in the Windows folder, I tried downloading the Media Creation Tool and creating an ISO file and running the upgrade from there ... no joy. I got errors like "There was a problem running preinstall.cmd scripts error for Windows Setup", Error 0xc19001e2, and Windows Update showing that it was trying to install update 1903 over and over again in a loop but never succeeding. Finally I discovered that this was a Dell PC that had Dell Encryption software installed on it. There wan't an entry in the Programs and Features control panel to remove the software, but it was sitting there in the system tray running every time the computer booted up. Since I wasn't using Dell's encryption solution, I found a way to remove it, using the Dell Data Security Uninstaller program found here .
