Several users have contacted us with questions after finding that taskhostex.exe consumes a lot of system resources or behaves inconsistently. Other users will see a boot error associated with this executable, wondering if it is a legitimate Windows component or a potential security risk.

What does Taskhost.exe do?
Windows uses taskhost.exe as the host for all DLL-based services. The process is very similar to svchost.exe (discussed above) because it is a generic method that can load other entities. For this reason, taskhost.exe can open several instances of itself to handle DLLs that are not necessarily linked.
