What is Secure Delete in Windows good and suitable for?
Detailed user questions and answers about Secure Erase in Windows 10, 11, and 12. The questions are divided into 10 categories to cover the different application areas.
1. What does "Secure Delete" mean in Windows and why is it important?
- Secure deletion means that files are overwritten in such a way that they cannot be recovered. This protects sensitive information from misuse, even if someone has access to the hard drive.
2. How exactly does "Secure Delete" work in Windows 10, 11, and 12?
- It overwrites the file multiple times with random numbers or zeros, making the original data unreadable. This method prevents recovery with conventional data recovery software.
3. What are the benefits of securely deleting data in Windows?
- It increases data security and privacy because deleted files are irretrievably destroyed. Perfect for anyone who wants to make sure that confidential data does not fall into the wrong hands.
4. When is it necessary to securely delete data?
- Especially with sensitive data, such as personal documents, business information or confidential projects, secure deletion is a good idea before passing on or disposing of the PC.
