Adobe provides product support from the general availability date of Adobe Acrobat and Adobe Reader for five years. The five-year date was October 15, 2017, meaning Adobe Reader XI and Acrobat XI have reached end-of-life. As a result, Adobe will no longer be providing technical support for those products. This also includes both product and, more importantly, security updates.
If either or both of these programs are installed on your computer it is strongly advised that you uninstall them as soon as possible. If you wish to stay with Adobe products, the Adobe Acrobat Reader DC can be downloaded from here.
Note: UNcheck any pre-checked additional options presented with the download. They are not part of the software and are completely optional.
If you use Windows 10, Microsoft Edge works great to read PDF documents. In addition, new features are included in the Windows 10 Fall Creators Update. See How Microsoft Edge will beat Chrome as the best PDF reader with the Fall Creators Update for additional information.
Another alternative is Free PDF Reader - Sumatra PDF.
