I'm using 2009 Toshiba W7, etc...and installed IE10 when it first came out. Used and reported as some others here no significant problems fwo or so months now.
recently tho, after the last batch of updates, I too kept loosing my saved web forums information liek passwords. So now I have to deselect "cache" and maybe another box. I was frustrated so I stopped using IE10 and got Firefox, but the same issue continues with firefox.
So as of now, I do not clean caches in IE10--- never a problem before the recent updates --- or Firefox. Its been a little confusing to establish wich boxes to check or not.
The other problem-- not related to browser --related to my start-up ---and that now appears to be fixed, since i went to my Toshiba page and downloaded some file. Sorry I forget what it was not BIOS related,
So first I started getting a stretched sign-in page and the cursor would not work,
so i would have to force quit with power button and restart, this worked ok almost every time after i did that once,
tho sometimes, I would only get black screen, but power button off fixed it each time,
and one time got not cursor movement after getting to desktop, power-off fixed it.
So, again, what ever I inloaded from Toshiba files appears to have fixed my problem because the stretched screen with non-operative cursor has not happen even once since.
Still have the new problem with browsers tho and they were not a problem with IE10, until this most recent batch of updates.
