Favorites quit working.

Have you tried resetting Internet Explorer and deleting the browsing history?

How do you reset Explorer 9 ?

Try following the instructions here.

I don't want to rest the whole thing and it was working fine last week. Is there another fix?

Resetting IE is not the same as resetting (reinstalling) Windows.  Except for whatever (if any) changes you made to IE settings (Security, Advanced), you won't notice any difference.  PC problems - be they hardware or software - are often there in a moment.  Just because it was working before doesn't mean anything ... a file could have gone missing or gotten corrupted, a virus could have been installed, a block of the drive could have gone out, etc.

I would try what has been suggested first.  You might be able to resolve it by doing a System Restore to a previous point when it was working.  I would suggest running a full scan for malware with Malwarebytes.  I would also suggest a CHKDSK /R from your command prompt and SFC /SCANNOW to fix any file/file system problems.

Windows remembers the last size of your window ... simply closing a full-screen window should remember it for the next time it is opened, but if it doesn't, then with only one window open (in full-screen), hit ALT to bring up the Menu Bar, click File, then Exit.

Thanks but even after reseting the browser and doing what you said it still doesn't work.

Have you done the following:

I did a full scan but how do yo do the command prompt?

I don't know how to edit the above post or add the snips.

It looked OK, here are 2 snips; could the answer be int he folder options in the control panel?

Thanks flash, I reset ie explorer 9 again and finally got it working! Now my top toolbar is black but I am glad the programs open maximized .I tried pressing F12 and setting the window size but that didn't work........good now.

Well that wasn't it. It was only a temporary fix because I chose to see full screen so it only opened to full size one time.
