Windows 10 update process not running through fiddler

[CW]

Hi,

i have installed the latest fiddler version on a Windows 10 PC. After that i have configured the ssl decryption, enable tls 1.1/ 1.2 and set the winhttp proxy settings. Traffic runs through fiddler but the Windowsupdate funktion runs only if i disable the proxy settings. I see that i getting many 408 Request.

Could some one help me?
