About this tag
Discussions about dllhost.exe, the COM Surrogate process in Windows, frequently involve troubleshooting issues such as high CPU usage, memory hogging, frequent process spawning, and problems with thumbnail generation or blank icons. Users report dllhost.exe starting every few seconds, causing system sluggishness, or failing to display thumbnails for videos and certain image formats. Common solutions attempted include running SFC /scannow, recreating the IconCache.db, scanning for malware, and disabling thumbnail previews. Some threads note that ending the dllhost.exe task temporarily restores normal icon display, but the issue recurs. The tag covers Windows 7 primarily, with mentions of Windows 10 and various hardware configurations.
