Google Chrome Task Host Process
chrome-taskhost.exe is safe. It's a legitimate Chrome helper process that hosts background tasks and utilities, enabling extensions, syncing, and site features to run in the background without impacting the main UI.
chrome-taskhost.exe is a Windows helper binary used by Google Chrome to host background tasks, utilities, and sandboxed workers. It enables Chrome features to run in separate, isolated processes, improving stability and security while background tasks such as extension support, site permissions, and syncing operate without blocking the main browser UI.
Located in the Chrome application folder, this process runs as a separate Windows process to host lightweight background tasks. It isolates work from the UI, helping prevent a single task crash from affecting the browser and enabling secure IPC between Chrome components.
Quick Fact: Chrome's taskhost approach supports multi-process isolation; chrome-taskhost.exe handles background duties so the main UI stays responsive.
