General mstask.chm Runtime Errors

Most CHM errors are due to missing or corrupt files. Your mstask.chm file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Windows), or deleted by a malware infection. Furthermore, mstask.chm file corruption could be caused from a power outage when loading Windows, system crash while loading or saving mstask.chm, bad sectors on your storage media (usually your primary hard drive), or malware infection.

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".

CAUTION : We strongly advise against downloading and copying mstask.chm to your appropriate Windows system directory. Microsoft typically does not release Windows CHM files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing mstask.chm and all other CHM files for Windows. An incorrectly installed CHM file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
