Quick reality check

If your UiPath sequence treats window sizes like optional suggestions you will get flaky automation and cryptic failures. Maximizing the target window with the Maximize Window activity makes selectors more predictable and gives your workflow a fighting chance to behave across different resolutions and multiple monitors.

Attach to the correct window first

Start by locating the target window with Attach Window or Use Application Browser. Pointing to the wrong window makes everything downstream act like a confused robot. Use a precise anchor element inside the window so the automation does not accidentally click on the wrong guest star.

Use the Maximize Window activity instead of hotkeys

Yes hotkeys are tempting because they feel clever. In practice they fail when users move monitors or when focus is imperfect. The Maximize Window activity talks to the UI framework directly and reduces mystery failures. Run it right after attaching to the window to get a consistent DOM layout for your selectors.

Harden your selectors for the maximized state

When a window is maximized some attributes will change. Update selectors to match the maximized structure and add wildcards for volatile attributes. Prefer stable anchors like titles or fixed element ids. If an element moves around use relative selectors or anchor base elements to avoid brittle XPaths that break when a tiny dialog shows up.

Add verification checks and avoid blind waits

After Maximize Window use Wait For Element or Element Exists to confirm the UI reached the expected state. A short Delay can be a safety net for race conditions but do not rely on blind waits for long periods. Log the result of Element Exists so failures are easy to trace and do not feel like random gremlins.

Test across environments and resolutions

Run the sequence on different screen resolutions and with multiple monitors attached. Test with the app window restored and with it already maximized. Log window existence, selector matches, and any fallback behavior so you can troubleshoot instead of guessing.

Quick checklist

• Attach to window with Attach Window or Use Application Browser
• Apply the Maximize Window activity early
• Update selectors for the maximized layout and use wildcards for volatile attributes
• Use Wait For Element and Element Exists after maximize
• Prefer anchors and stable attributes over absolute paths
• Test on different resolutions and monitor setups and log outcomes

Follow these steps and your UiPath automations will stop losing their minds when a user moves a second monitor. Use Maximize Window before critical interactions and pair it with verification checks so your automation behaves like it actually wants to work.
