I did you one better. I removed password protection from your original file. See attached. I would post the steps but I don't know if that violates some sort of EE policy.

Save the file in Rich text format RTF
Open the file with WordPad
Save the RTF file with a different name
Open the new RTF file with Word
Save the document as a word document
Delete the two rtf files

It destroys formatting though. Attached is your doc after applying the steps above.

The document only has Forms protection, which is to prevent accidental changes to the fixed data. It is not a security measure, so PAdocIT has not violated any policy.

However, since this a how-to, and not a do-it-for-you site, perhaps PAdocIT has misunderstood its spirit.

You can create an unprotected document by inputting the file into a blank document. In 2007 and on, that is via Insert tab, Text group, Object dropdown, Text from file... and browse for the document. In 2003 and earlier, it is Insert menu, then File... and browse.

Well in that case this is what i did using office 2010 Notepad++ and HxD Hex Editor

1.) Open a protected document in MS Word
2.) Save as "Web Page (*.htm; *.html)", close Word
3.) Open html-document in any Text-Editor
4.) Search <w:UnprotectPassword> tag, the line reads something like that: <w:UnprotectPassword>ABCDEF01</w:UnprotectPassword> (password is already in hex-format)
5.) Keep the "password" in mind
6.) Open original document (.doc) with any hex-editor
7.) Search for hex-values of the password, which is stored in reverse order. (e.g. If password is AB CD EF 01. Then the password is in the .doc file as 01 EF CD AB)
8.) Overwrite all 4 double-bytes with 00, Save, Close
9.) Open document with MS Word, Select "Tools / Unprotect Document" (password is blank)
