AÂ paging fileÂ (aka: “page file” and “virtual memory”) enables the system to remove infrequently accessed modified data from physical memory to let the system use physical memory more efficiently for more frequently accessed data. Windows also uses the page file to store data when physical memory (RAM) is full.
Encrypting the page file prevents malicious users from reading data that has been paged to disk, but also adds processing overhead for filesystem operations.
This tutorial will show you how to enable or disable virtual memory paging file encryption in Windows 10 and Windows 11.
Windows uses 128-bit encryption to help protect file sharing connections by default. Some devices do not support 128-bit encryption and must use 40- or 56-bit encryption.
This tutorial will show you how to change to useÂ 128-bitÂ orÂ 40- or 56-bitÂ encryption for file sharing on all networks in Windows 11.
Device encryption helps protect your data, and it’s available on a wide range of Windows devices. If you turn on device encryption, the data on your device can only be accessed by people who’ve been authorized. If device encryption isn’t available on your device, you may be able to turn on standard BitLocker encryption instead.
Device encryption is available on supported devices (ex: tablet or 2-in-1 laptop) running any Windows 10 edition. If you want to use standard BitLocker encryption instead, it is only available on supported devices running Windows 10 Pro, Enterprise, or Education. Some devices have both types of encryption. BitLocker is not available on Windows 10 Home edition.
This tutorial will show you how to turn on or off device encryption in Windows 10.
