How to change the Windows 10 Pro User Account Control level
User Account Control, usually called UAC, is a Windows 10 security feature that asks for permission before an application or system action makes important changes. These changes may include installing software, modifying protected folders, changing system-wide settings, or altering other user accounts.
The notification level affects how often Windows 10 Pro interrupts your work with a security prompt. A higher setting provides stronger protection against unwanted changes, while a lower setting creates fewer interruptions. The right choice depends on how often you install software, how much control you need over system settings, and whether other people use the computer.
Changing the UAC setting takes only a few steps, and the setting can be adjusted again whenever your needs change. Before lowering it, it helps to understand what each option does and what protection may be reduced.
What User Account Control does
UAC separates everyday activity from actions that require administrator-level permission. Even when your Windows account belongs to the Administrators group, Windows generally runs ordinary programs with standard permissions. When a program requests elevated access, UAC asks you to approve the action.
This design helps limit the impact of malicious software, unsafe installers, and accidental system changes. For example, a downloaded application may need administrator access to write files into the Windows folder. The UAC prompt gives you a chance to verify that request before Windows allows it.
A UAC notification does not automatically mean that a program is dangerous. Legitimate installers, driver packages, and Windows tools can require elevation. However, an unexpected prompt deserves attention, especially when you are not installing software or changing a setting.
UAC also works differently depending on the account type. An administrator may only need to select Yes, while a standard user may need to enter administrator credentials. The exact wording can vary according to the selected notification level and local security settings.
Check the current notification level
The quickest way to view the current UAC setting is to open the Start menu and search for Change User Account Control settings. Select the matching Control Panel result. You can also open Control Panel, choose User Accounts, select User Accounts again, and then click Change User Account Control settings.
A vertical slider appears with four positions. The marker shows the level currently used by Windows 10 Pro. Moving the slider changes how Windows responds when applications or users request administrative access.
The default setting is usually the second position from the top. It provides a useful balance for most home and small-office computers: Windows warns you when an application attempts to make changes, but it does not usually interrupt you when you change Windows settings yourself.
Before moving the slider, consider whether the computer contains personal documents, financial information, work files, or multiple user accounts. A stricter setting is generally appropriate when several people use the device or when applications are installed frequently.
Understand the four UAC options
Each position changes the timing and appearance of permission prompts. The settings are arranged from the strongest notification behavior to the weakest. The slider changes notifications; it does not turn Windows security features such as Microsoft Defender off.
| UAC setting | What Windows does | Practical effect |
|---|---|---|
| Always notify | Prompts whenever you or an application attempts to make administrator-level changes | Highest awareness and strongest interruption level |
| Notify me only when apps try to make changes to my computer, with secure desktop | Prompts for application changes and dims the desktop during the prompt | Default balance for most users |
| Notify me only when apps try to make changes to my computer, without using the secure desktop | Prompts for application changes without dimming the desktop | Fewer visual interruptions, with less protection against input interference |
| Never notify | Does not notify you about elevation requests | Lowest protection and generally not recommended |
Always notify is the most cautious option. Windows can display a prompt when you make changes yourself, such as adjusting system settings. The desktop is dimmed during the prompt, which helps prevent other programs from interacting with the approval window.
Notify me only when apps try to make changes, with the secure desktop enabled, is the normal Windows 10 Pro choice. The prompt appears when an application requests elevation, but routine changes made directly through Windows usually do not trigger the same level of interruption.
The third option keeps application notifications but disables the secure desktop effect. This may be useful if dimming causes display problems or takes too long on a particular computer, although it offers less separation between the prompt and other running processes.
Never notify effectively disables standard UAC prompts for the account. This can make the computer feel less restrictive, but it also makes unauthorized changes easier to approve or carry out. It is best avoided for ordinary daily use.
Change the UAC slider safely
After opening the UAC settings window, drag the slider to the desired position. Read the description beside the slider so you can confirm the behavior you are selecting. If you are unsure, leave the setting at the default second position.
Click OK. Windows may display a confirmation prompt asking whether you want to allow the User Account Control Settings program to make changes. Select Yes if you are intentionally changing the setting. The new level normally takes effect immediately, so a restart is not usually required.
Test the result by opening a trusted administrative tool, such as Computer Management or a system settings utility. Do not use an unknown program merely to test UAC. If the prompt appears as expected, the new configuration is active.
If the slider is unavailable, the account may not have sufficient rights, or a local security policy may control the setting. On Windows 10 Pro, administrators can also manage UAC behavior through Local Security Policy or Group Policy. Those advanced policies can override or refine the behavior shown by the slider, so avoid changing them unless you understand the effect.
Choose a level for everyday use
For most personal computers, the default setting is the most practical option. It warns you when an application requests administrator access while avoiding repeated prompts during ordinary work. This allows you to review unexpected software activity without making common Windows tasks unnecessarily difficult.
The highest setting can be useful for a shared family computer, a device used for testing unfamiliar software, or a system where strict change control matters. It may produce more prompts, but that extra attention can help prevent accidental modifications.
The third setting may suit users who find the dimmed desktop distracting or experience a graphics-related problem during UAC prompts. The security difference is important: the secure desktop helps isolate the approval screen from other processes, so disabling it should be a deliberate choice rather than a way to silence an annoyance.
Avoid choosing Never notify simply because an installer or application keeps requesting permission. Repeated prompts may indicate that the application needs elevation by design, is poorly configured, or should not be trusted. Check the publisher, download source, and file name instead.
UAC changes do not repair damaged system files, resolve every permissions error, or improve computer speed by themselves. If Windows is showing broader update or system problems, use a focused troubleshooting process. For example, the steps in this Windows Update guide can help when update failures, repeated restarts, or pending installations are involved.
Troubleshoot prompts and unexpected behavior
If UAC prompts appear too often, first note which application is generating them. A legitimate program may be configured to run with administrator privileges, or it may be trying to write files into a protected location. Reinstalling it from the official source may correct a damaged installation, but do not approve prompts from software you cannot identify.
If a trusted program stops working after you increase the UAC level, do not immediately disable UAC. Try launching the program normally, check for an updated version, and review its own settings. Some older applications were designed for earlier Windows versions and may need compatibility adjustments.
A prompt that appears when you are doing nothing deserves special attention. Cancel it, open Task Manager if necessary, and inspect recently installed applications or startup items. Run a scan with Windows Security, particularly if the prompt began after downloading a file or visiting an unfamiliar website.
If the prompt does not appear at all, confirm that the slider is not set to Never notify. Also check whether a work or school administrator manages the computer. Managed devices can apply policies that limit the settings available to local users.
Problems with a blank, frozen, or incorrectly scaled UAC prompt may involve graphics drivers, display scaling, remote desktop software, or secure desktop behavior. Updating Windows and trusted device drivers can help, but make changes one at a time so you can identify what resolved the issue.
Apply these sensible UAC habits
A notification level is most effective when combined with careful approval decisions. The goal is to recognize legitimate administrative actions without training yourself to click through every prompt automatically.
- Keep the default UAC level unless you have a clear reason to change it.
- Approve a prompt only when you know which program requested access and why.
- Use the highest level when testing unfamiliar software or protecting a shared computer.
- Avoid the Never notify option on computers used for banking, work, or personal records.
- Keep Windows, Microsoft Defender, browsers, and commonly used applications updated.
When an application repeatedly asks for elevation, investigate the application rather than treating UAC as the problem. A trusted installer may need permission once, while a program that requests access every time it starts may have a configuration or compatibility issue.
It is also useful to remember that UAC is one layer of protection. Maintain backups, use reputable download sources, keep security software active, and use a standard account for routine work when practical. These measures reduce the chance that one mistaken approval will lead to wider damage.
Apply the setting with confidence
Changing the Windows 10 Pro UAC level is a straightforward way to control how Windows handles administrator permission requests. Open Change User Account Control settings, compare the four notification levels, select the option that matches your risk tolerance, and confirm the change.
For everyday use, the default setting normally provides the best balance between security and convenience. If you change it for troubleshooting or a specific task, review the setting afterward and restore a stronger level when the task is complete. Open the UAC settings now, choose deliberately, and treat every future permission prompt as a request worth checking.
