[QUOTE="Andy Ful, post: 1016843, member: 32260"] It is better. Bypassing SUA usually requires bypassing isolation between different accounts. The UAC (also max) on Admin does not change the account. See for example: [URL unfurl="false"]https://www.tiraniddo.dev/2017/05/reading-your-way-around-uac-part-1.html[/URL] [URL unfurl="false"]https://www.tiraniddo.dev/2017/05/reading-your-way-around-uac-part-2.html[/URL] [URL unfurl="false"]https://www.tiraniddo.dev/2017/05/reading-your-way-around-uac-part-3.html[/URL] Edit. There were some UAC bypasses in the wild that worked with UAC on max on Admin and did not work on SUA. I know one example that still works. It is blocked by Defender, but I am not sure if all AVs block it too. I tested the bypass a few minutes ago - here is the info from the ConfigureDefender log: ************************************************************************* ************************************************************************* Event[0]: Time Created : 27.12.2022 12:50:02 ProviderName : Microsoft-Windows-Windows Defender Id : 1116 Message : Produkt Program antywirusowy Microsoft Defender wykrył złośliwe oprogramowanie lub inne potencjalnie niechciane oprogramowanie.
