As of 2015, Flash players available for Windows XP are Adobe Flash Player and Silverlight. To download Adobe Flash, visit Get.Adobe.com, and follow the prompts. To download Silverlight, visit Microsoft.com and follow the directions on the Installation Instructions tab.
Silverlight is a free Web browser plug-in by Microsoft. It can be used on PCs, Macs and Linux systems and is supported by most major browsers such as Firefox, Google Chrome and Safari. It is currently not available in the Microsoft Edge browser.
Adobe Flash Player is supported by almost every browser that still uses Flash. However, Google Chrome and Mozilla Firefox browsers no longer support Adobe Flash due to an irreparable security flaw.
