ATLOCK is a Windows privacy utility for people who share a computer with family members or other users and want to limit access to selected files or stored credentials. It combines file protection, a password-organizing tool and a system-locking function in one application. These tools support different privacy needs without requiring a separate program for each task.
File Guard protects selected files, including documents, receipts and photos, by changing their account ownership and placing them behind a custom password. This can help prevent other users from moving, editing or deleting those items, whether by accident or intent. The feature is intended for specific files rather than an all-purpose computer account system, so users can keep shared access to the PC while restricting access to chosen data.
Password Vault provides a place to record usernames and passwords and organize entries by the platform or service they belong to. This can replace handwritten credential notes with a digital list inside ATLOCK. Users can group related entries for easier reference, while the vault's purpose is credential organization rather than broader account management. Total System Lockdown offers another kind of protection: it locks the PC when its user steps away, helping prevent someone nearby from using an unattended session.
The three features suit different situations in a shared household or other setting where a computer is used by more than one person. File Guard is for keeping selected personal or important files away from casual access; Password Vault is for keeping login details arranged in one place; and Total System Lockdown is for temporarily securing the whole computer. Using the relevant feature lets a user address a particular privacy concern without withdrawing the computer from everyone else's use.
ATLOCK is freeware for Windows 10 and Windows 11, with support for 32-bit and 64-bit Windows 10 systems. Its compact set of tools is focused on access control and privacy rather than general-purpose system maintenance. The interface includes text labels and instructions, although text scaling and interface resizing are not available. As with any password-based utility, users should choose a memorable password and keep a separate, secure record of credentials needed to regain access to protected information.
