I believe that some of you may ever receive a PDF with password protection in which you are not allow to edit, selecting texts and even printing the file content. Actually this is a great feature to prevent your content to be stealed by someone, but some time the file’s owner can also forget the PDF password. In this case, how to solve the problem? Hehe! I found a great tool that allow you to decrypt and remove password from any PDF file with “owner” password set, this tool named PDF Password Remover Tool. Note that this tool does NOT remove “user password” that prevents unauthorized access to PDF file.

When we talk about PDF, then we will think about Acrobat Reader which it is a great tool to view, print and collaborate on PDF files. The drawback of Acrobat Reader is that it just can view the PDF files, but it can’t use to modify the PDF files.

When I worked in office last time, there are some of PDF files need to be modified, but I was too lazy to search from Internet to find a tool to modify PDF files, so I have wasted my times to retype in Word document files. But now, I know there are 3 great tools which can modify PDF files easily and they are free.

1. PDF-XChange Viewer – is a smaller, faster and more feature rich than any other FREE PDF Reader/Viewer/Editor available.

2. doPDF – is a free PDF creator that does what the name suggests, creates PDF files.

3 PDFTK Builder Portable -  is the lightweight PDFTK Builder packaged as a portable app, so you can modify, split and watermark your pdfs wherever you go.

Once I play online game, I can play few hours and even more than 10 hours, it is seem like I have crazy life. I know there is one software named Eyes Relax can helps avoiding eyes-related problems when working at a computer for several hours, it can reminds me about taking those break, but I think it’s seem not useful for me.

Anyway, if you have children at home, and you want to control their computer playing time, then Eyes Relax is very helpful as it can enter the password-protected Parent Mode in which the user is forced to take breaks (during the break the computer is locked). This is very useful since children often forget about the real world and play video games much too long.

If you don’t have too much time to monitor your children playing computer, then you can try Eyes Relax to lock their computer and stop them play computer at your desired time.
