Issue: How to fix error code:0x80070426?

I‘m trying to figure it out what causes “An error occurred during program initialization. If this problem continues, contact your System Administrator. Error Code: 0x80070426.” Perhaps, one of the recent Windows 10 updates is faulty? An explanation and the solution would be appreciated.

Solved Answer


Error code: 0x80070426 is likely to appear due to the mismatching system processes and initialization errors. If Microsoft Essentials happened to remain on the system and you have upgraded to Windows 10, which offers the protection of improved Windows Defender, the error might appear. Specifically, the program is not compatible with third-party applications. Another explanation stems from the unsuccessful installation of the recent Windows 10 updates. There are several reasons for such failure. In short, this error should not be ignored as it makes your operating system more vulnerable to outside virtual infections. Furthermore, due to the problem, the efficiency of the computer might deteriorate as well. This system error might also initiate Mail application synchronization issues.
