Is this really the version you are looking for? Kentico Xperience 8 Documentation is no longer updated. Use the switcher in the header to choose your product version.
If you need to uninstall Kentico from your computer, you can use the three options provided in the Installer.
To remove Kentico after your evaluation of the system, choose the Remove Kentico 8 from my computer option. This option will NOT uninstall .NET Framework, IIS or SQL server.
There may be a few cases, when you will want to remove only the Kentico program files (the files needed to install the web projects). For example, when you want to move the program files to a different hard drive or when you want to launch a live site and you no longer need the program files on your server. For this purpose, choose the Remove only Kentico program files option.
Uninstalling the program files will also remove external utilities, like Kentico Installation Manager or Kentico Import Toolkit.
If you have installed multiple web projects (instances) and you want to remove only some of them, use the third option Remove one or more registered web projects. Using this approach, you can also choose to remove only the web project files (this option will also remove Windows services, performance counters and event log sources) and keep the database for further use.
For managing individual web projects you can also use the Kentico Installation Manager utility.
