I have a machine with IE11 and when I clear the internet history, the progress bar won't go away until 6 seconds. Also if I clear the IE cache from the browser with just history selected, it takes about 12 seconds until I see "internet explore finished clearing your history" on the bottom.
For the progress bar method, I would use this in cmdprompt: RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 1, which research says clears the history.
In perfmonitor > Disk, doing this shows a lot of stuff going with log files being read/written to in the "webcache" folder. So I tried deleting it after killing task host, but it just created a new folder "webcache" and the clearing history process still takes just as long
C:\Users\username\AppData\Local\Microsoft\Windows\WebCache
What other things about my machine can be causing history deletion to take so long every time? Is there additional history information I can clear somewhere else?
