Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the Windows operating system version
    Run 'winmsd' or 'systeminfo' from command prompt, or check the System Properties window (Win+Pause). Look for OS Name and Version fields.
    Affected if The operating system is Windows 2000 (any version), Windows XP (any version), Windows Server 2003 (any edition), Windows 98, Windows 98se, or Windows Me.
  2. Check the installed Windows build number
    Run 'systeminfo' and locate the 'OS Version' line, or run 'winver' command. Note the build number (e.g., 2195 for Win2000, 2600 for XP).
    Affected if The build number matches an unpatched version of the affected operating systems listed above.
  3. Verify if security update MS05-011 is installed
    Open Control Panel > Add or Remove Programs, check 'Show updates' box, and look for 'Security Update for Windows (KB885835)'. Alternatively, run 'systeminfo' and look for Hotfix(s) in the output.
    Affected if The security update MS05-011 (KB885835) is NOT listed among installed updates.
  4. Query the registry for the patch status
    Open Registry Editor (regedit), navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates\Windows, and check if KB885835 entry exists under the relevant service pack branch.
    Affected if The registry does not contain an entry for KB885835 under the Windows updates key.

The system is affected if it runs any unpatched version of Windows 2000, Windows XP, Windows Server 2003, Windows 98, Windows 98se, or Windows Me, and does not have security update MS05-011 installed.
