Most modern software uses online verification. A key shared publicly on the internet is usually blacklisted by the developer almost immediately.
If you are looking for these features without the risk of using "grey-market" keys, Windows has several built-in tools that do the same job safely:
Open Command Prompt as Admin and type sfc /scannow . This is the "official" way to repair corrupted system files for free.
Licensed users get priority help if a "fix" accidentally breaks a system function.
Many sites offering "free" premium keys are gateways for malware or adware.
