Just today I've noticed something new to be occurring that never happened before until my graphics card crashed recently which resulted in a Blue Screen of death. Upon opening Windows Task Manager occasionally there will be 2 processes running that disappear once the Task Manager has been open for a couple minutes. SearchFilterHost.exe & SearchProtocolHost.exe I've seen these 2 processes running before however it was quite rare. Now if I leave Task Manager closed for quite a while then re-open it, these 2 tasks reappear & won't disappear until I've left Task Manager open for a couple minutes. This is a regular occurrence I've noticed for the past few hours today. Although they're not using up a whole lot of memory or CPU it does strike me as odd why they're re-appearing every time I open Task Manager when it's been closed for over 5 minutes or so. What could this mean? Could Defragmenting help even though my HDD is only 2% fragmented? What should I do?
