If you’ve decided to transition from Windows 10 to Windows 11, opting for a clean install can offer significant advantages over the standard upgrade. While the upgrade promises to maintain your files and settings, a clean installation ensures you can fully leverage the security benefits integral to Windows 11, particularly the Smart App Control feature. Curious about how this process works? Let’s explore.
Why Should You Clean Install Windows 11?
Upgrading to Windows 11 brings numerous enhancements, but one crucial aspect often overlooked is its security feature—Smart App Control. This exclusive functionality acts as an advanced safeguard against malicious software and helps to keep your PC safe by proactively blocking threats.
However, to utilize Smart App Control effectively, you must perform a clean installation of Windows 11, which involves erasing all existing data on the system. This requirement is non-negotiable; without a clean slate, this security feature cannot be activated. While alternative methods exist, they frequently revert after system updates or restarts.
Understanding Smart App Control
Smart App Control is an impressive security enhancement in Windows 11 that protects against harmful software and potentially unwanted programs (PUPs).Unlike traditional antivirus solutions that react post-execution, Smart App Control prevents potentially harmful applications from starting by scrutinizing their behavior and digital validation.

According to Microsoft, the tool primarily evaluates the digital certificates of apps to ascertain their trustworthiness. It employs advanced AI and cloud-based intelligence to assess the safety of applications, relying on their behavioral patterns and telemetry data. Apps with valid digital signatures are granted access, while unsigned apps are carefully analyzed for any potential risks.
Taking a zero-trust stance, Smart App Control only allows approved applications to run. Once an app is blocked, users cannot simply unblock it; doing so requires disabling Smart App Control, which is complicated as it often necessitates a reset or a clean installation to re-enable the feature. While this stringent approach might seem excessive, it brings top-tier security quality down to everyday users.
Executing a Clean Installation of Windows 11
If you’re committed to performing a clean install of Windows 11, it’s essential to follow these steps diligently to ensure Smart App Control is activated and your data remains safe:
- Create an external backup: Prioritize data safety by backing up important files to cloud storage or an external hard drive. This step is crucial to prevent any data loss during the installation process.
- Sync data with your Microsoft account: Log into your Microsoft account to ensure your settings and application preferences are synchronized. Use the Windows Backup app to verify your last successful sync.

- Note your software and product keys: Safeguard important local keys stored on your PC to avoid losing valuable software access.
- Enable Secure Boot and TPM support: Ensure both TPM and Secure Boot features are enabled in your UEFI settings, as Windows 11 installation is contingent upon these prerequisites.
The most straightforward way to install Windows 11 is by using the Windows Media Creation Tool. When prompted, select the custom installation option and make sure to delete the current system partition before proceeding with the Windows 11 installation.
During the setup phase, enabling the Send optional diagnostic data feature is crucial, as it supports Smart App Control’s functionality. Once installation is complete, you can locate Smart App Control via the Windows search bar, and it should automatically start in Evaluation mode.
Be aware that if you frequently utilize unsigned applications, Smart App Control may disable itself after the evaluation period. To regain full functionality, a system reset might be necessary, alongside a commitment to avoiding those types of applications. By paying attention to these essential steps during your Windows 11 setup, you’re positioning yourself for a seamless and secure user experience.
