用户帐户控制：修订间差异

User Account Control received a design refresh again to match with the new Fluent design aesthetics introduced with [[Windows 11]].

The [[Windows 11 2024 Update|2024 Update]] largely improves upon the existing User Account Control mechanism by introducing ''Sudo for Windows'', an open-source command-line tool directly inspired by the Unix <code>[[w:Sudo|sudo]]</code> command, which allows users to run other programs as the <code>root</code> superuser.<ref>Adoumie, Jordi. [https://devblogs.microsoft.com/commandline/introducing-sudo-for-windows/ Introducing Sudo for Windows!], ''Windows Command Line''. 8 February 2024. Retrieved 9 February 2024.</ref> Despite the name, Sudo for Windows is not based on its Unix counterpart, and is instead written from scratch in the [[w:Rust (programming language)|Rust]] programming language. It does not aim to be compatible with the original implementation either due to the differences between the Windows and Unix permission systems, notably the absence of a superuser account. It can be enabled via the <code>sudo config --enable</code> command, or within a developer-specific toggle included as part of the [[Settings]] application.

Sudo for Windows supports multiple modes of operation with varying levels of isolation from unelevated processes. The new window mode merely triggers a User Account Control prompt for the given command and exits. The input disabled and inline modes work by running a second, elevated instance of Sudo itself which runs the given command and redirects its standard streams (excluding the standard input stream if running in input disabled mode) via [[w:remote procedure call|remote procedure call]]s to the original, unelevated instance.

With [[Windows 11 build 27718|build 27718]], the elevation prompt has been changed slightly. In [[Windows 11 build 27754|build 27754]], the prompt has been slightly updated with the heading and application name in boldface, as well as minor padding and button size adjustments.
