What Causes The Error 4201

Normally these kinds of errors are caused because of the program that it relates to and so below are the main causes of the following error:

  • Specific Windows files and settings are damaged or corrupt
  • Registry keys cannot be found
  • Files have been removed

How To Fix The 4201 Error

Step 1 – Rename The WMI Folder

The “WMI” folder is basically what Windows uses to help load up a number of important pieces of software & data for your system. If you are experiencing the 4201 error, it generally means that the references to this folder are damaged and should be changed. Here’s how to do this:

  • Use msconfig to switch to safe mode boot
  • Boot to safe mode
  • Run cmd.exe as an administrator
  • Type “cd C:\Windows\System32\LogFiles\WMI”
  • Type “rename RtBackup RtBackup2”
  • Use msconfig to switch to normal boot mode
  • Reboot and find event viewer working

Step 2 – Clean Out The Registry

One of the big causes of the 4201 errors is through the “registry” database of your computer. This is a large database which stores vital information & settings for your PC, and is used continually to help Windows to read the files, settings & options that it needs to run. Although the registry is one of the most important parts of every Windows system, it’s continually causing a large number of problems thanks to the way it will often become corrupted and unreadable. This is the cause behind many 4201 errors, and needs to be resolved by using a reliable “registry cleaner” application.

This step is best completed by downloading RegAce System Suite, and letting it clean out any of the problems that your system may have inside.
