When you do a system restore on your computer, or have new computer, there are some applications you want to make sure you install; Adobe Reader, Adobe Flash Player, Adobe Shockwave, Google Chrome browser, which is the most popular web browser, a virus protection software.
Also make sure all the updates have been installed for the operating system you are running, such as Windows 7 or Windows 10 security patches and service packs. Extra bonus try using CutePDF Writer which is a print driver used to convert your documents to pdf format. Yes, I know you have the ability to convert Word documents into a PDF format, but you will be surprised by the number of times you use CutePDF Writer for other applications. I also like to run “CCleaner” which is used to clean up unwanted files and cookie from your computer. Be sure to step backup schedule for your entire operating system and applications after you have installed all the essential programs.
