When Windows determines your PC is idle, it indexes folders, files and their contents to make searching faster. Therefore, it could create or rebuild the index of your drive when you are preparing for a gig.
The Windows Search service is responsible for indexing the content of your files and folders and making the results available for faster searching. If you disable this service, you can still search for files and folders, but your searches will be slower as the index is not available. Windows will display a message: “Your searches might be slow because index is not running”.
Refer to section Optimizing Windows Services, to disable this service if you do not need it, or if you want to get more performance at the expense of getting faster search results.

Make sure that both options are unchecked and click on OK. If asked to apply on all subfolders, confirm. It may take a couple of minutes to apply this setting to all subfolders and files, depending on how much content is on your drive.
