With 10GB of free online storage, Box's Personal service now is one of the more robust free offerings. Box also limits file sizes to 250MB each. It does more than sync and have online access; it also offers tools for commenting on or editing documents (it won't replace an office suite like Google Drive, which you'll find below in Office Suites, though it could just as easily go in this category).
If you use a desktop email client like Outlook, Thunderbird, or even Windows Mail, you're probably not getting as much spam-fighting power—especially with POP3 email accounts. Stick SPAMfigher on the system—it works directly with Microsoft to make it as tough against spam as possible. (The Windows version is totally free for home use; the Mac version is only free for 10 days.)
Standard and Poor's is one of the most prestigious companies in the world. If you are familiar with the U.S. stock market, then you know that the company publishes the S&P 500, an index of the 500 most promising large publicly-traded companies in various industries. Standard and Poor's also rates and provides indices for smaller companies. The company's reports focus on financial information and credit ratings and can be very useful in tracking down leads in the financial sector.
Your local library isn't just a place you go to find a new novel without paying for it. Libraries subscribe to a number of different business directories, which makes them a perfect place to get leads for free —especially for B2B salespeople. These directories aren't limited to resources like Internet reverse lookups, although such a tool can be very useful if you're looking for business leads. Many companies make it their business to organize information about both the company and their consumers. This information is compiled into a huge database, and this database is pure gold for any salesperson looking to create a new lead list.
Put the PrtScn (Print Screen) button to actual use. LightShot is a tiny utility that takes over that button. Push it and you can pick what part of the screen to turn into a screenshot, plus annotate with tools like text and arrows. It's also available for leading web browsers to capture what's on a page. Once captured, you get choices to save to a file, the clipboard, the cloud, social networks, or to just search for similar shots in Google.
