Concerns: - After running these switches, you mentioned that no programs would run and that the Quick Launch bar was empty. - Additionally, you found that certain folders in the Program Files directory contained no executables. 3. Missing Executables: - To identify which folders in the Program Files directory contain no executables, we can help you with that. Recommendations: - Identifying Empty Folders: - To identify the folders in the Program Files directory that are missing executables, you might need to manually inspect these folders. It's crucial to ensure that essential system files are not deleted.
