Windows 11'deki yeni güvenlik katmanları nasıl çalışıyor ve sistem bütünlüğünü koruyor?

When I first upgraded my family laptop to Windows 11 for the kids’ schoolwork, the TPM‑enabled secure boot was the first thing that caught my eye. I had to enable TPM 2.0 in the BIOS and let the OS take over the attestation process. The moment I booted, Windows greeted me with a quick “checking integrity” screen—nothing you can see, but underneath it’s the firmware measuring each boot component and storing the hashes in the TPM. If anything is tampered with, the chain of trust breaks and you get a boot‑failure or a warning. In practice, I’ve never seen a false positive, but the peace of mind that my system won’t silently load a compromised loader is huge, especially when I’m juggling school assignments and code reviews on the same machine. A few weeks later I tried the new isolated Windows Sandbox for testing a third‑party CLI tool. Because the sandbox leverages the same hardware‑based isolation (VSM/Hyper‑V) and inherits the TPM’s measured boot, the tool ran in a container that can’t reach my main file system or credentials. The combination of device security (Secure Boot + TPM) and runtime isolation meant I could spin up a disposable environment without worrying about lingering malware. Real‑world impact? My kids’ accounts stay locked down, my dev work stays clean, and I’ve stopped worrying about “what if someone slipped a rogue driver” during a quick Windows update. It’s a small extra step in the upgrade process, but it pays off in day‑to‑day confidence.
