That appears to be a third-party Task Manager alternative, but I cannot independently verify the “Microsoft veteran” claim or determine whether the download is safe from the link alone.
Before installing it, consider:
- Check whether the project provides a verifiable developer identity, source code, changelog, and privacy policy.
- Scan the downloaded file with reputable security software and submit its hash or sample to VirusTotal.
- Review its digital signature and ensure it is downloaded only from the official project domain.
- Create a restore point or test it in a virtual machine first, especially if it requires administrator privileges.
It may offer useful features beyond Windows Task Manager, but third-party system utilities should be evaluated carefully because they operate with extensive system visibility and sometimes elevated privileges.
