The genuine prevhost.exe file is a software component of Microsoft Windows Operating System by .
The genuine «prevhost.exe» is a Microsoft system file residing in «C:\Windows\System32» which should not be removed. It is an important component of the Windows operating system’s ability to use Preview Handlers. These lightweight utilities, each custom-designed and specially registered for one file type, (e.g., «.xlsx» for Excel workbooks), enable applications like Outlook or Explorer to present a rich read-only preview of such files in the «reading pane» without starting their associated application. These are usually DLL’s for which «Prevhost.exe» is Microsoft’s default «COM surrogate» allowing the Handler to run «out of process» so that if an error occurs only the surrogate terminates, not Explorer or Outlook. (The «COM surrogate» method also enables previewing of files elsewhere on a network.) On a 64-bit system, a version of «prevhost.exe» exists in «C:\Windows\SysWOW64» to interface with 32-bit Preview Handlers; the Handler’s registry data must specify that version’s CLSID as its surrogate.

A clean and tidy computer is the key requirement for avoiding problems with prevhost.

Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
