There was a similar problem on IE10 on Windows 7 where certain websites would not load properly after running CCleaner. The problem was solved in the new v4.0 release so I am sure they will be fixing it on Windows 8 as well. Look under the thread lower on the page titled "IE10 on W7 Bug" for info. Try going into Internet Options on IE10 and delete Cookies and Website data to fix the problem and then uncheck everything under IE on CCleaner when you run it or the error will reoccur. You will have to use Internet Options on IE10 to delete things until the problem is corrected.
1 the issue is with Internet Explorer and not ccleaner (any eraser does it)
2 the issue is very old (as far back as ie7 if not further, and may not effect everyone the same amount/version-of-ie
3 the issue is usually tied to history or cache corruption (so those and index.dat are the only things you need to troubleshoot: uncheck each one, one at a time, clean and try internet explorer if not those try each entry, you'll find it)
4 the issue may or may-not be related to having the Internet Explorer setting for cleaning up after last close.
To fix there are two ways
1) Restart the computer
2) open internet options (from control panel if you have too) and delete settings should be right there.
It might be a different problem if you still have an error after deleting everything under Internet Options. Maybe try resetting IE in Internet Options. If that doesn't work then I am out of ideas other than reinstalling IE. If you prefer Chrome then I would just use that for the time being anyway.
I wasn't placing blame. Was just saying that there was a compatibility problem with IE10 on Windows 7 and CCleaner v3.8 that wasn't around on IE9. Everything works fine again after the v4.0 release. I thought this might be a similar problem so I told him what worked for me.
IE10 is back to normal now, following the Internet Options > General > Delete instructions above.
It only worked after unticking the "Preserve Favourites website data" box. Must say, it is slightly counter-intuitive to have to untick a box to delete something on a page of ticked delete boxes. All became clear after actually reading what the options did :-)
Haven't used CC4 since, but having now used Chrome on my new PC, I can't see me rushing back to IE10 anyway...
If I can narrow down which CC4 option causes the problem I will report back.
