How do I password-lock a Word file?

Use File → Info → Protect Document → Encrypt with Password, enter the password twice, then save. Word will ask for it when someone opens the file.

Is Restrict Editing the same as locking the document?

Yes for most “prevent editing” searches. Restrict Editing locks what people can change after the file is open. Encrypt with Password locks whether they can open it at all.

Can someone copy text from a locked Word document?

Often yes—Restrict Editing mainly blocks edits. For tighter control, combine locks with careful sharing settings, or share a PDF when copying/printing must be limited.

How do I unlock a Word document I locked earlier?

Open Review → Restrict Editing → Stop Protection, enter the password if prompted, then save. Clear an encryption password under File → Info → Protect Document → Encrypt with Password.

Can I lock a Word document in WPS Writer?

Yes. Open the .docx in WPS Writer, apply protect/encrypt options available in your build, save as .docx, and verify the lock in Microsoft Word before sharing.
