Mcupdate.exe Errors

Though not common, there are instances when users may and do encounter errors with the mcupdate.exe process. Errors associated with this process, tend to be fairly common problems. Your only job need only be to tackle the problem as soon as you can.

Here is some of the problems people report experiencing with this process:

  • The mcupdate.exe process consumes 100% of system resources, for an extended period of time.
  • Task scheduler encounters an error: Task mcupdate_scheduled: the task image has been tampered with or is corrupted within Event ID 1101, 245, 1554, 7654.
  • After doing a startup repair, the mcupdate.exe process fails to load.
  • The mcupdate.exe process repeatedly crashes, with the following error message: APPcrash-mcupdate.exe with System.IO.FileNotFoundException
  • Two scheduled tasks; both mcupdate_scheduled and mcupdate are created by Media Center.

These errors can morph into even bigger problems if not immediately addressed; these problems include but are not exclusive to the following:

  • Microsoft Windows takes a considerably long time to boot up.
  • Certain applications refuse to run while in Windows.
  • System performance decreases quite considerably.
  • Certain applications will not install on your computer.
  • The system occasionally crashes.

Cause of Mcupdate.exe Errors

The mcupdate.exe error that you’re experiencing may be due to a corrupted system file. Corruption of system files will adversely affect system performance, and operating system integrity.

There are many different scenarios that may have occurred on your computer that resulted in the corruption of integral system files. These are:

  • An improper installation or uninstallation.
  • The improper removal of a hardware device or application.
  • An improper shutdown of your system.
  • The result of a virus attack.

All of the scenarios outlined above, may result in the corruption or deletion of your Windows system files. This corruption may result in the operating system referencing incorrect file data that is required for the proper working of some applications.

The multitude of malicious files can affect your system in so many different ways, such as by modifying and/or corrupting the registry, so that the computer fails to load correctly. After these malicious files are tracked down and removed, the registry is forever altered, so your system performance may still run well below par. That is the main reason why you must also repair the registry if you want a fully restored system.

Any and all files on your computer will typically be found in their default file locations, however, some of these files can be easily moved or have their names altered by malicious files. If you suspect that you may have a malicious file on your computer, you should first verify the location of the suspected file. You should also use Windows Task Manager, to see what is running on your computer at that moment.

To load Windows Task Manager, simply right click on the Taskbar and select Open Task Manager, once Windows Task Manager loads up, click on the Processes Tab, to see what is running on your system, and how much resources it’s consuming.

Any DLL files that may be running in the background will not show up in the Processes Tab area of Windows Task Manager, this is because DLL files operate as part of other processes. If your computer is infected with a malicious file, then you may see similar program names running at the same time, only with slight misspellings; this is a form of disguise deployed by the computer hacker. You may also see a malicious file with a file name very similar to mcupdate.exe. Make sure you verify the file location on any files or processes that you suspect.

Use Windows Restore

In the event that the recommend programs above fail to repair the error(s), you could attempt to use Windows restore to fix the error. It’s a long shot, but definitely worth a try.

It’s most likely that the solutions above are sufficient in fixing the problem; however, if not, then I recommend Windows restore as your final option. For more help, I recommend you check out my post on the Restore feature.

Run a Registry Scan

The registry is an integral area of the computer that is the culprit for a great many DLL errors. These errors are usually caused by the large number of DLL files that are utilised on your system. Every time you use your system, at least a hundred different DLL files are located, with help from the Windows registry. The main problem is that registry entries are hardly ever removed by the operating system, even if the associated application has been uninstalled, as the built-in uninstallers are typically unable to effectively do that.

If this area of the operating system gets damaged or corrupted, it typically manifests itself in the form of errors, such as the mcupdate.exe error you may be experiencing right now. Fortunately, it is possible for you to do something about it. Repairing the registry manually isn’t much of an option, given the complexity and the inherent dangers of fooling around with this area of the system. The most viable option is to use a professional registry cleaner tool like RegCure Pro, which is capable of accessing your registry, detecting and repairing where applicable.

Run a Malware Scan

I’ve stated, in many instances in this article, that mcupdate.exe errors are typically caused by virus infections. Thus, to fix these problems, you can opt to either replace the mcupdate.exe file (which is not advisable) or run a full virus scan of your system, which is the best option.

There are several solutions around that are capable of effectively locating and removing malicious files from your computer. I’m going to assume that you already have one of them, installed on your system, so go ahead the scan your hard drive, in it’s entirety.
