By following a number of procedures, a “prevhost” application error can be resolved. Since it can disrupt the processes of some programs and even infect these with virus or malware, which can cause program or system instability, it poses a threat to your operating system. As some would agree, you should get an error of the sort repaired immediately. Otherwise, your computer will not function accordingly and can lead to errors that are more critical. If left unfixed, you may be temporarily or permanently unable to accomplish even basic tasks such as open media files via a downloaded application or utilize the media player.

What Is Prevhost?

Preview Handler Surrogate Host or prevhost, usually 31 bytes in size and can be located in a Windows System subfolder, is a hidden .exe or executable Windows file associated with Home Premium Windows Vista Service Pack 1. It is designed to assist with the function of certain programs especially those featuring media or data from a third-party source. By default, it will load automatically every time Windows or any program that relies on it is initialized. However, although not recommended, the original setting can be modified and disabled.

What Is Prevhost Error?

With it being an executable file, Preview Host will likely lead to an error or a crash if a procedure during execution has not been followed accordingly. Either that or it has been maliciously (by virus or malware) or manually disabled. If the malfunction is left unrepaired, some programs will not work properly. In addition, if you have failed to eradicate the problem while opening and running the file, high-memory usage will be a concern.

Causes of Prevhost Errors

A program is in conflict with Home Premium Windows Vista Service Pack 1

Corrupted or incomplete download of prevhost.exe or other executable files

Malicious programs have deleted prevhost

The executable file is infected with virus or malware

Windows registry keys that are associated with prevhost or Home Premium Windows Vista Service Pack 1 are corrupted

With prevhost.exe error, Win 7, Windows 8, Windows XP, Windows Vista, or any other Windows versions can malfunction and can disrupt an activity while using your computer. Since it can come up unexpectedly and can stop a program before enabling you to save your progress on it, it can be bothersome. To be safe, consider getting the download from a reliable source instead of other executable file distributors that are making it available. The product they give away may be free but they can be potentially harmful. You cannot guarantee that what you have received is uninfected with virus or malware.
