Enter the file name, and select the appropriate operating system to find the files you need:

There may be many causes for the failure of some file of Windows OS, but most of the causes are as follows:

  • Abnormal shutdown of the system results in missing or corruption of the file
  • The file is accidentally deleted or replaced by some software, or the original file is modified
  • The file ismodified or destructed by viruses maliciously
Generally, if your operating system can run normally, and you can enter the operating system successfully, we suggest you do not reinstall the system, because it's too cumbersome and time consuming to reinstall system. You can first try to download normal file and place it back into the original folder, and the corresponding problems will be solved accordingly.

If your operating system is attacked by virus, for the first step, you should download some certain anti-virus software, and let the anti-virus software check the files of all hard disks in order to remove all viruses, and then you should download the normal files and placethem back in the original folder.

Tip: How to correctly select the file you need
1 If you know MD5 value of the required files, it is the best approach to make choice
2 If you do not know MD5 value of files, you can choose the appropriate files by adopting the following three steps:
 (1) View the operating system version. (Method: Click "My Computer" on the desktop-> "Properties" to view the operating system version)
 (2) If your original file is just corrupted but not lost, then please check the version number of your files. (Method: Click your original file, and then click on the right key to select "Properties" from the pop-up menu, you can see the version number of the files)
 (3) Depending on the version number of your existing operating system, and version number of the files, you can select the corresponding files from the list below to download the required files.
If you still can't find the file you need, you can send an Email to us. (file@pconlife.com)
