Hi Brain Lorge,1. Do you remember any changes to your computer prior to the issue occurring?2. What issues do you face with DW20.exe and Hotfixinstaller.exe?I'd suggest you follow these steps and check if it helps. Step 1: a. Boot your machine in safe mode and check if the issue occurs at startup.b. Also, to be on a safer side, run a complete system scan to remove malicious software in safe mode, then boot into normal mode and check if your machine locks up. Step 2: There could be a third party software conflict causing the issues to occur. I'd have you put your machine in a clean boot state to eliminate third party software conflicts. Note: Do not forget to restart your computer in normal state after downloading the update in clean boot stateAzeez Nadeem - Microsoft Support[If this post was helpful, please click the "Vote as Helpful" (green triangle) button.
