This is part of the Dell systems and it's used to automatically download all the Support Assists packages on the supported platforms.
You can uninstall the application in case you don't want to use SupportAssist in the future, but if you change your mind, then visit the official website to download the installation package again as it will be always available.
While on the download page, check the operating systems and devices to see exactly if it's supported by your device.
