(v) To the extent included with Windows, Word, Excel, PowerPoint and OneNote are licensed for your personal, non-commercial use, unless you have commercial use rights under a separate agreement.

no if the trial license expired.

technically, it is expired becoz Win10 allowed you to use full feature for few days on first startup. once the evaluation expired, the water mark appears and appearance customization are disabled but other features are still usable.

regardless, it is consider illegal becoz u dont have license to use the OS once evaluation is over.

5. Authorized Software and Activation. You are authorized to use this software only if you are properly licensed and the software has been properly activated with a genuine product key or by other authorized method. When you connect to the Internet while using the software, the software will automatically contact Microsoft or its affiliate to conduct activation to associate it with a certain device. You can also activate the software manually by Internet or telephone. In either case, transmission of certain information will occur, and Internet, telephone and SMS service charges may apply. During activation (or reactivation that may be triggered by changes to your device’s components), the software may determine that the installed instance of the software is counterfeit, improperly licensed or includes unauthorized changes. If activation fails, the software will attempt to repair itself by replacing any tampered Microsoft software with genuine Microsoft software. You may also receive reminders to obtain a proper license for the software. Successful activation does not confirm that the software is genuine or properly licensed. You may not bypass or circumvent activation. To help determine if your software is genuine and whether you are properly licensed, see (aka.ms/genuine). Certain updates, support, and other services might only be offered to users of genuine Microsoft software.
