Windows Update – Service not running or Windows System apps appear as from unknown publisher

There are two symptoms to the same problem in Microsoft Windows:

  1. Windows Update cannot currently check for updates, because the service is not running. You may need to restart your computer
  2. When you Run As Administrator mmc.exe, notepad.exe, regedit.exe and any other program, you get — Do you want to allow the following program from an unknown publisher to make changes to this computer?

These errors started to appear after one of the Intel RAID 1 (Intel ICH8R/ICH10R SATA RAID controller) drives have failed, and was replaced with the new drive. The RAID rebuilt was successful, however the above symptoms have appeared.

Where is the problem?

Windows Cryptographic Services. The service have two folders under Windows/System32 directory:
C:\Windows\System32\catroot
and
C:\Windows\System32\catroot2

One of them have the log file – edb.log, that was full of the error messages.

Also in the GUID-named subfolders there are two database files called “catdb”.
C:\Windows\System32\catroot2\{127D0A1D-4EF2-11D1-8608-00C04FC295EE}\catdb
and
C:\Windows\System32\catroot2\{F750E6C3-38EE-11D1-85E5-00C04FC295EE}\catdb

They both were missing. Folders were empty… And do not try to copy them from another PC. It would not work. Windows will automatically delete them after Cryptographic Service is started.

Where is the solution?

Update your RAID driver! Yes simple as that, update driver (to at least version: 11.7.0.1013 from 12/3/2012), and these files are regenerated automatically. On modern Intel i7 CPU it took about 1 hour.

P.S. I believe that this applies not only to Windows 7, but also to Windows 8.1 and Windows 10.
P.S.S. Running Microsoft Windows Resource Checker (SFC.exe) does not do anything useful in this case.

Disappearing folder – bug in Windows 7

In process of testing one of our automation software I hit interesting Windows 7 bug. First I found it in our software, and right away tested this scenario on Windows 7, and bug was there.

The bug. Create folder on the Desktop.

Right click on Desktop
New folder

New folder appears and cursor blinks allowing to change the name for the folder.

Cursor at the end

Place cursor at the end of folder name, and enter dot (.) character.

Dot at the end

After pressing Enter key the folder disappears.

Folder disappears

But do not worry, it will come back after reboot, or after refresh (F5 key).

After refresh

Appears that this bug/behavior… that only Windows 7 is affected. Other Windows versions I tested does not have this bug, even Windows XP and upcoming Windows 8 behaves correctly (see screenshots at the end of the post).

A side note. By “correctly” in this case I mean, that folder does not disappear, however perhaps, there is another bug. The dot “.” character disappears in all Windows versions. This of course depends on interpretation, for example, I also tested this on Ubuntu 10, and Ubuntu (and probably most nixes) allows dot (.) at the end of filename.

Why this happens? Every filename consists of two parts: filename and extension. These two parts are separated by dot (.) character. Windows Shell hides this dot from you, and when you enter “filename.”, it thinks, that this must be a filename without extension, so it stores only filename. In theory you should be able to trick shell by adding more dots, like “filename…”, but Windows 7 Shell reduces them to no dot. Of course you can create file or folder with one or more dots at the end, but for this you will need a normal file manager, like Far Manager (which is open source). Also, keep in mind, that you will not be able to delete this file or folder from desktop using Windows Shell, you will need to switch to file manager again.

Note 1. Windows Server 2008 R2 is based on the same codebase, so it has the same bug.
Note 2. Operating Systems used in the test:

  • Windows 7 Professional 64-bit
  • Windows Vista Enterprise
  • Windows Server 2008 Enterprise
  • Windows Server 2008 R2 Datacenter
  • Windows Server 2003 Enterprise
  • Windows 8 Consumer preview
  • Windows XP
  • Ubuntu 10
