## Guides to Revive Non-Functional Radeon Software in Windows

Users who need to fix AMD Radeon Software not working can’t open that app and access its settings. Are you among those users? If so, you can fix AMD Radeon Software not opening on a Windows PC with the resolutions below.

1. Press the Ctrl + Shift + Esc keyboard key combination to activate Task Manager.
2. Select Task Manager’s Details tab.
3. Look for and right-click RadeonSoftware.exe to select the End process tree option.
