What are perfwci.ini Error Messages?


General perfwci.ini Runtime Errors

perfwci.ini file errors often occur during the startup phase of Windows, but can also occur while the program is running. These types INI errors are also known as “runtime errors” because they occur while Windows is running. Here are some of the most common perfwci.ini runtime errors:

Most INI errors are due to missing or corrupt files. Your perfwci.ini 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, perfwci.ini file corruption could be caused from a power outage when loading Windows, system crash while loading or saving perfwci.ini, bad sectors on your storage media (usually your primary hard drive), or malware infection. Thus, it’s critical to make sure your anti-virus is kept up-to-date and scanning regularly.

Download perfwci.ini Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying perfwci.ini to your appropriate Windows system directory. Microsoft typically does not release Windows INI 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 perfwci.ini and all other INI files for Windows. An incorrectly installed INI file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
