You just installed Windows 11 and think the work is done? Know that if you don’t make some important adjustments, your experience could be filled with crashes, security issues, and even performance loss. Many people ignore these first steps and end up discovering the hard way: slow programs, disabled features, and even risks of hacking. It is precisely to avoid this that I have gathered the 6 most important actions right after installation.
Windows 11: What to Configure Right After Installation
Windows 11 arrived with lots of new features in design, app integration, and new productivity tools. But, like any operating system, it doesn’t come “ready” to meet every user’s needs. Small initial adjustments make all the difference in ensuring security, speed, and convenience in daily use.
System and Driver Updates
It may seem obvious, but the first step is to check if all Windows Update updates have been applied. This step ensures that security vulnerabilities already patched by Microsoft are not left open on your computer. Additionally, installing the latest drivers—especially for video, audio, and network—can radically improve performance.
According to Microsoft Brazil, monthly updates fix critical vulnerabilities exploited by hackers and ensure compatibility with new applications. Ignoring this step can leave your PC slow and vulnerable.

Activate Antivirus and Integrated Security
Windows 11 comes with Windows Security, which includes antivirus, firewall, and ransomware protection. Even so, many people disable these features without realizing it. The ideal is to activate all layers of defense right after installation.
Reports from CERT.br (Center for Studies, Response, and Treatment of Security Incidents) show that malware attacks have increased precisely on poorly configured machines. Setting up security from day one drastically reduces the risk of infection.
Adjust Privacy Permissions
Another essential point is to review the privacy settings. The system collects data to personalize ads and suggest content, but you can limit this. Disabling unnecessary permissions for microphone, camera, and location is a way to protect your digital life.
According to Kaspersky, a Russian multinational cybersecurity company, 61% of users who suffered online scams had not adjusted their privacy settings, which opened gaps for suspicious applications.
Customize Startup and Performance
After a few days, you may notice that the computer takes a long time to boot. This happens because many programs are set to start automatically with the system. Adjusting Windows 11 startup can reduce this time by up to 40%.
Tools like Task Manager allow you to disable unnecessary software at startup. Additionally, activating high performance mode in the power options makes a difference for those using heavy programs, such as video editing and gaming.
Set Up Backup and Recovery
Few remember this, but a simple update error can corrupt important files. Therefore, set up an automatic backup on OneDrive or an external hard drive immediately.
According to research from FGV Tecnologia, 30% of Brazilians have lost important files due to lack of backup. Having a saved copy prevents headaches and ensures that documents and photos remain safe even in system failures.
Explore Productivity Features
Last but not least, take advantage of the new features that Windows 11 offers. Functions like Snap Layouts (window organization), custom widgets, and integration with Android applications can transform your work routine.
According to a study by the international consulting firm Gartner, companies that adopted Windows 11 with training on using these features recorded an increase of up to 25% in team productivity. In other words, it’s not just about security but also about exploring the most that the system can offer.
Now that you know the 6 essential steps, you can use Windows 11 with more security, performance, and convenience. Simple adjustments ensure a smooth experience without frustrations.
