I has found that Searchprotocolhost.exe in Windows 7 is running all of the time and uses high cpu or memory, such as using up to 36% of CPU. searchprotocolhost.exe is slowing down my old computer.
what is Searchprotocolhost.exe? It is Windows Search Protocol Host which is created by Microsoft Corporation and located in the C:\Windows\System32 folder.
How to safely disable searchprotocolhost.exe or stop searchprotocolhost running?
Type services into the search box and press enter --> Double-click the Services(Local) --> look for Windows Search --> Right-click it --> choose properties --> click stop. Change startup type to disable then click apply.
