@Schulte I am stuck at “ Uninstall Symantec Endpoint Protection “ it is asking for password, which I don’t have. And I realized one thing, your earlier point may be right about this laptop being from company. Here is what has happned. I bought this laptop from Dell directly, but later to access company’s email on this laptop, I added microsoft account (company provided) on this laptop. It seems company has got extra control over my laptop, and they might have pushed this Symantec Endpoint Encryption. And it seems I can’t do anything this tool now. I removed company provided microsoft account, it is not helping anyway.
