Remove PDF files restrictions with PDF Unlocker

Some PDF document files are protected by the creator by disabling specific functions on the PDF reader. A common restriction is to prevent copying or editing the document to protect the copyrights of the owner. One way to copy such PDF files is to take a screenshot and use an OCR tool to convert it to text. An easier way is to use a PDF unlocking program.

PDF Unlocker is a free application that can remove the restrictions set by the creator. Simply drag the PDF file to the shortcut of application and it will automatically create a non-protected copy of the PDF file. (Thanks GHacks)

    PDFunlocker from www.pdf-unlocker.com is NOT freeware. Even the commercial version 2.0 cannot unlock all restrictions (as opposed to the advertisment). The filled-in fields cannot be saved to "unlocked" .pdf file by Acrobat Reader 8.

    It was a freeware when I wrote it. Seems like I have to look for another application. When I find one, I will update this post.

    Meanwhile, you can search google for the earlier version.

The task manager is ideal for real-time analysis of CPU and memory utilization. It even displays a short history of CPU utilization in the form of a graph.
