Whenever you create, copy or move a file or folder, Windows Search Indexing feature scans the location in order to index all the contained items. The indexed items help speed up the search process. Once search index is built for all locations and saved items, Windows can provide you with search results instantaneously, as it no longer has to manually find the item from the specified location. The Windows search is basically responsible for retrieving and displaying the search results from the list of indexed items. The search index keeps running in the background as a Windows service named WSearch. Although it significantly speeds up the search process, it may consume significant system resources. While people who are using high-end PCs do not care about processes that consistently consume physical memory resources, users with slower computers can feel a difference in the response time while performing even routine tasks. Another reason for disabling the service is that if, for some reason, the indexed items are not being displayed correctly, turning it off and performing a cold reboot of your system can fix the issue. Read on to find out how to disable the search indexing service in Windows 8.
