The windows should be closed immediately.

To change the given sentence "Close the windows immediately" into the passive voice, you can follow these steps:

1. Identify the subject and the object of the sentence:
- Subject: You (implied)
- Object: windows

2. Move the object (windows) to the beginning of the sentence:
- Windows (object)

3. Use the appropriate form of the verb "to be" followed by the past participle of the main verb (close):
- Windows are closed

4. Add the optional agent (the doer of the action), using the preposition "by" before it:
- Windows are closed (by someone)

Putting everything together, the sentence "Close the windows immediately" in the passive voice becomes:
"The windows are closed (by someone) immediately."

Note: If you don't know who closed the windows, you can omit the agent, and the sentence would be: "The windows are closed immediately."
