How can I protect my files from being changed or deleted in Windows?

The best way to protect files from being changed or deleted in Windows is to utilize the built-in security features of the operating system. By taking advantage of user and file access control, encryption, and data recovery tools, users can ensure that their important data remains safe at all times.

User and File Access Control:

Windows includes a variety of user and file access control options that allow administrators to determine who can access specific files and folders on a computer, as well as what type of access they have. This can be implemented through the native Windows User Account Control (UAC), which allows administrators to set permissions for individual users or groups of users. Administrators can specify whether users are allowed to read, write, execute, or delete files and folders, as well as modify their properties. Additionally, UAC also allows administrators to assign specific rights and permissions to users, such as allowing certain users to view, edit, or delete specific files or folders.


Encryption is one of the most reliable ways to keep data secure, as it prevents unauthorized users from being able to access and modify sensitive information. Windows includes several built-in encryption tools such as BitLocker and EFS that can be used to protect important data. BitLocker is a tool that allows users to encrypt their hard drives while EFS stands for “Encrypting File System” and is used to encrypt individual files or folders. With these tools, administrators can protect their data with a password or key, and can even set up an automatic backup system so that any changes made to the files can be quickly recovered in the event of data loss or corruption.

Data Recovery:

Data recovery is another important component of keeping files secure. In the event that data is corrupted or accidentally deleted, Windows includes several tools that can help users quickly recover their data. The Recycle Bin is a temporary storage location where deleted files are stored until they are permanently removed from the system, meaning users can easily restore any lost files by selecting them in the Recycle Bin and clicking the “Restore” option. Additionally, the System Restore feature can be used to roll back changes to the system if necessary. Finally, Windows also includes a shadow copy utility that allows users to create snapshots of their files and folders, which can then be accessed and restored in the event that a file becomes corrupted or deleted.

Overall, there are a variety of ways to protect files from being changed or deleted in Windows, from user/file access control to data recovery. By taking advantage of these built-in security features, users can ensure that their data remains safe at all times.
