What's Wrong?
When I clicked the Cowork button on Claude Desktop, a PowerShell prompt appeared. I clicked OK and restarted. After restart, my AMD Radeon Vega 8 display driver was completely replaced by Microsoft Basic Display Adapter, causing screen resolution to be locked at 1024x768 (stretched and blurry).
Device: HP EliteBook 745 G5
GPU: AMD Radeon Vega 8 (Ryzen 5 PRO 2500U)
OS: Windows 10 Pro Build 19045
Fix required: Manual reinstall of AMD Adrenalin driver (~1-2 hours troubleshooting)
The Cowork feature should not modify system drivers without explicit user warning and consent.
What Should Happen?
Cowork feature should NOT modify system drivers. If any system-level action is required, user must be clearly warned with full explanation before proceeding.
