  5. SFC /scannow already run with no errors found

One physical disk

  1. A primary partition c: with the OS (Windows 7 Ultimate 64-bit SP1)
  2. An extended partition that contains

    • Logical drive d: (NTFS)
    • Ext4 partition with Ubuntu 11.10
    • an Ubuntu SWAP partition
    • Logical drive F: (NTFS) with Windows swap file

But it is handled by GRUB.

All things worked painlessly, but a Windows Update I started experiencing some problems. One example to make it clear:

If I go to Start » Run "notepad" , then I type something on notepad and try to save on "C:\filename.txt" I receive the "Out of files" error. I can even create a new directory of which I'm the owner with the same results.

If I go to Start » Run "notepad c:\filename.txt" then the file is created without problems.

Just to complete the scenario, even if I enable the built-in Administrator account and log in, same errors are given.

Hi Daniele. Please don't rollback edits unless you have a very good reason to do so. – slhck Apr 10 '12 at 11:59
I just made some typo – Daniele Berti Apr 10 '12 at 12:42
Is Notepad the only program this happens in? Can you use the "right mouse click"/New/Text Document to add a text file to the root of C:? – CharlieRB Apr 10 '12 at 13:28
Microsoft Support does not acknowledge an "out of files" error. Search yourself if you like. Not saying you are not seeing what you see, just pointing out MS doesn't want to agree. You also say "no viruses" but what about Malware and Spyware? Yes, it is possible the Windows Update is borked. So, uninstall the update, or try using a restore point from before the update. You might even have to reinstall W7. – Bon Gart Apr 10 '12 at 13:54
Could you add a screenshot of the error? – Bob Apr 10 '12 at 13:58
