It is not recommended to disable UAC unless you are an advanced user

User Account Control (UAC) is a security feature in Windows 11. This feature is enabled by default to keep your PC safe from possible risks when you make specific changes to with your PC. When enabled, UAC displays a warning message asking you to allow or deny those changes on your PC. It may also ask for the admin password before allowing you to make unauthorized changes. Unless you are an advanced user who wants to ignore those prompts, you should never turn off UAC prompts. When UAC is turned off, you won't receive any warning prompts about the consequences of changes. So, if you are a normal user, you better avoid changing the default state of UAC.

UAC serves as a preventative measure against viruses, malware, and other harmful software. When programs or system processes try to make modifications that can endanger your computer or jeopardize your data, it asks for your approval. By turning off UAC, you remove this line of defense and make it more likely that harmful or unauthorized acts may be carried out without your knowledge. UAC protects your system's integrity by limiting illegal changes to essential system files and configurations. Any attempt to change these files or settings when UAC is active will request you to grant permission. This lessens the possibility of unintentional or accidental adjustments by ensuring that you deliberate and approve changes.

In such scenarios, it's crucial to exercise caution and take appropriate security measures:

• Limited and Controlled Environment: You should only disable UAC in restricted settings, such as isolated virtual machines or standalone PCs. By doing this, the possible effects of any security lapses or unapproved modifications are reduced.
• Alternative Security Measures: It's crucial to put alternative security measures in place when UAC is turned off. These include using a firewall, keeping your operating system and apps up to date, and maintaining antivirus software.
• Enable UAC for Internet-Facing Activities: When engaging in internet-facing activities, such web browsing or file downloads, it's very crucial to maintain UAC enabled. This adds another line of defense against possible security breaches.

In conclusion, sophisticated users who fully comprehend the dangers involved and implement the necessary security measures should be the only ones authorized to disable UAC. Disabling UAC should be done carefully. To ensure the security and integrity of their Windows system, the majority of users should keep UAC enabled.
