CCleaner and IE9

I've been a long time user of CCleaner and when cleaning Windows it has always been pretty quick at carrying out the task.

However, since I moved on to Windows 7 and IE9 when it came out this process takes ages. When I click on analyse it takes ages going through IE files. It never used to do this when I ran Windows XP and IE8. Is this normal.

I've even used Disk Clean Up prior to CCleaner so IE files should no longer be present but CCleaner still takes ages going through them as if they were never deleted.

Should it always take this long.
