In an increasingly digital world, protecting your computer from unauthorized access is paramount. Windows 11, the latest operating system from Microsoft, comes equipped with several features that allow for remote access, which can bolster productivity but also pose potential security threats. Whether it’s a case of malware, a misunderstanding regarding the settings, or an unsecured network, knowing how to secure your system is essential.
Understanding Remote Access
Before diving into prevention techniques, it’s crucial to understand what remote access means in the context of Windows 11. Remote access allows someone to connect to your computer from a different location. While this feature is useful for IT support or collaboration, it can also be exploited by malicious actors if not properly secured.
Types of Remote Access You Should Be Aware Of
Remote Desktop Protocol (RDP)
: This is a proprietary protocol created by Microsoft that allows users to connect to another computer over a network connection. RDP is useful for accessing files and applications from a different location but can pose security risks if enabled without proper protection.
Third-Party Software
: Applications like TeamViewer, AnyDesk, and Chrome Remote Desktop provide remote access capabilities. While they are designed for legitimate purposes, if misconfigured, they can open up your system to unauthorized access.
Remote Management Tools
: These tools are often used by IT administrators for system maintenance and troubleshooting. Like RDP, if not managed carefully, they can be exploited.
Signs that Someone is Accessing Your Computer Remotely
If you suspect someone is accessing your computer without your permission, look for these signs:
-
Unexplained Changes
: If you notice changes in files, settings, or applications that you didn’t make, it’s possible someone else is accessing your system. -
High Network Activity
: Monitor your network to see if data is being sent or received at unusual hours or levels. -
Unfamiliar Applications
: New software you didn’t install, especially remote access programs, can be a sign of unauthorized access. -
Slow Performance
: If your PC is slower than usual and you are not running resource-intensive applications, it may be because someone is accessing it remotely.

How to Prevent Remote Access on Windows 11
Now that you understand the landscape of remote access, let’s explore various strategies to secure your computer.
1. Disable Remote Desktop
If you are not using Remote Desktop at all, it’s a good idea to disable this feature to eliminate associated risks.
Steps to Disable Remote Desktop:
2. Configure Your Firewall
Windows Firewall helps protect your PC from unauthorized remote access. Make sure it is active and configured properly.
Steps to Configure Windows Firewall:
You can also create rules to block specific applications or connections if needed.
3. Use Antivirus Software
Using a reliable antivirus or anti-malware program can add an extra layer of security. Look for software that offers real-time protection and can block known threats.
4. Manage User Accounts
window user accounts can be targeted for unauthorized access. By managing accounts effectively, you can prevent unauthorized logins.
Steps to Manage User Accounts:
Make sure to set strong passwords for all accounts, using a combination of letters, numbers, and symbols.
5. Regularly Update Your Operating System
Windows updates often include patches for security vulnerabilities. Keeping your system updated minimizes the chances of exploits.
Steps to Check for Updates:
6. Disable Unused Services
Windows 11 runs several services that can be used for remote access. If you are not using features like Remote Assistance, consider disabling them.
Steps to Disable Unused Services:
7. Change Default Settings of Third-Party Remote Access Tools
If you use third-party software for remote access, review its settings to ensure maximum security. This can include:
-
Disabling File Transfer
: If this isn’t needed, turning it off can prevent unauthorized file access. -
Two-Factor Authentication
: Enable this option if available, as it adds an additional layer of security. -
Monitor Active Sessions
: Regularly check to see if any unknown sessions are active. Most applications provide an interface for this purpose.

8. Secure Your Network
Your home network may be an entry point for unauthorized remote access. Here are a few practices to secure it:
-
Change the Default Router Password
: Most routers come with default usernames and passwords that are easy to find online. Change these as soon as you set up your router. -
Use WPA3 Encryption
: Ensure your Wi-Fi is secured with the highest available level of encryption. -
Enable a Guest Network
: If you have visitors, create a separate network for guests. This limits access to your primary devices. -
Regularly Update Router Firmware
: Firmware updates often include critical security patches. Check your router manufacturer’s website regularly.

9. Monitor Your Computer
Keeping an eye on your computer’s performance and network activity can help you spot any irregularities early.
-
Task Manager
: Press
Ctrl + Shift + Esc
to open Task Manager. Check for unfamiliar applications or processes that are consuming high resources. -
Resource Monitor
: In Task Manager, go to the
Performance
tab and click on
Open Resource Monitor
for a more detailed examination of network activity.

10. Use a VPN for Enhanced Security
Using a Virtual Private Network (VPN) can help protect your data when you are online. It hides your IP address and encrypts your internet traffic, making it harder for hackers to intercept your information.
11. Implement User Education
Educating yourself and anyone else using the computer about best practices in security can significantly reduce the risk of unauthorized access.
-
Avoid Phishing Scams
: Be cautious of unsolicited emails or messages asking for personal information or directing you to untrusted websites. -
Social Engineering Awareness
: Understand the techniques used by malicious actors to manipulate individuals into providing access. -
Regular Training
: If you’re in a business setting, consider regular training sessions on cybersecurity.
