There are many disadvantages of open source software. These include the following. Some open source software is not reliable, due to the fact that there is little money put into development, and anyone can view, edit, and redistribute. There is often no qualified support available, the only support, if any is usually via forums and other users. Many open source programs are not compatible with
. windows and other applications, often causing the installation costs to increase. As open source software is edited and redistributed by many users, there is no guarantee of regular updates, so your software can easily become outdated very quickly.
