How to secure your Windows 11 Home PC and Microsoft Office 2021 Standard

Security policies for Windows 11 Home and Microsoft Office 2021 Standard

In an increasingly digital world, it is more important than ever to protect your systems and data. Both Windows 11 Home and Microsoft Office 2021 Standard contain built-in security features, but their full effectiveness depends on proper configuration and best practices.

Why safety counts

Whether at home or in the office, cyber threats such as phishing, malware and ransomware are omnipresent. By taking proactive measures, you can protect your devices, personal data and professional files from unauthorized access and data loss.

1. always keep Windows 11 Home up to date

Regular updates are crucial to fix known vulnerabilities and implement new security features. Windows 11 Home installs updates automatically by default - but check the status regularly.

• Open Settings > Windows Update
• Click on "Check for updates"
• Install all available updates and restart your system

2. activate Microsoft Defender Antivirus

Windows 11 Home comes with Microsoft Defender Antivirus, a powerful real-time protection against viruses, ransomware and other threats.
To check whether it is active:

• Go to Settings > Privacy & Security > Windows Security > Virus & Threat Protection
• Make sure that Defender is activated and no threats have been found

3. use a local account or a Microsoft account with 2FA

When setting up Windows 11 Home, you can either log in with a Microsoft account or a local account. For maximum security, we recommend using a Microsoft account with two-factor authentication (2FA) enabled.

4. protect Office 2021 with a password

Office 2021 Standard offers options to protect your documents with passwords. This prevents unauthorized access to confidential information.

• Open a document > File > Information > Protect document
• Select "Encrypt with password"
• Enter a strong password and confirm it

5. use the protected folder in Microsoft Defender

The "Monitored folder access" protects important folders (e.g. documents) from unauthorized changes by ransomware. Activate it as follows:

• Go to Windows Security > Virus & Threat Protection > Ransomware Protection
• Click on "Manage monitored folder access"
• Activate the function and add important folders

6. deactivate macros in Office if not required

Macros are a common attack vector in Word or Excel documents. If you do not use macros, deactivate them by default:

• Open Word or Excel > File > Options > Trust Center > Trust Center settings
• Click on "Macro settings"
• Select "Deactivate all macros"

Activate two-factor authentication (2FA) for your Microsoft account

If you are using Microsoft Office 2021 Standard, your Microsoft account is probably linked to the license key and cloud services such as OneDrive. Activating the Two-factor authentication (2FA) for your account can prevent unauthorized access even if your password is compromised.

How to activate 2FA:

• Visit https://account.microsoft.com and log in.
• Go to Security options.
• Select Further security options and activate the Two-stage verification.

You can set up 2FA via an authenticator app, SMS or email confirmation codes.

Protect your Microsoft Office 2021 documents with a password

Microsoft Office 2021 Standard offers integrated options to protect your sensitive files with a password. This is particularly useful when working with confidential documents.

How to protect Office documents with a password:

• Open a document in Word, Excel or PowerPoint.
• Click on File > Information > Protect document.
• Select "Encrypt with password".
• Enter a secure password and confirm it.

Attention: If you lose your password, Microsoft cannot recover it. Keep it in a safe place.

Use Microsoft Defender SmartScreen when surfing the web

The integrated SmartScreen filter in Microsoft Edge warns you about malicious websites, phishing attempts and suspicious downloads. This function is integrated in Windows 11 Home and Edge and helps to prevent cyber attacks.

To activate SmartScreen:

• Open Microsoft Edge.
• Click on the three dots at the top right > Settings.
• Go to "Data protection, search and services".
• Make sure that "Microsoft Defender SmartScreen" is activated.

Use strong passwords for Windows and Office

A strong password is your first line of defense against unauthorized access. Avoid simple passwords such as "123456" or "password".

Tips for strong passwords:

• At least 12 characters
• Combination of upper and lower case letters
• Numbers and special characters
• No personal information (date of birth, name)

Install trustworthy security software

In addition to Windows Defender, you may want to consider a third-party security solution, especially if you need advanced features such as VPN, parental controls or password managers.

Popular options:

• Bitdefender
• Norton 360
• Kaspersky Internet Security
• McAfee Total Protection

Conclusion

Securing your Windows 11 Home PC and your Microsoft Office 2021 Standard environment is an ongoing task. Through regular updates, the use of integrated security features and best practices, you can protect yourself and your data from a variety of cyber threats.

If you follow these steps, you will not only increase the security but also the reliability of your system - and that will give you the peace of mind you need in the digital age.
