A few months ago Microsoft confirmed that some customers were experiencing issues when attempting to install Service Pack 1 for Windows 7.
Specifically, the software giant pointed out that users were reporting coming across two error messages, namely 0x8004a029 and 0x80004005 - E_FAIL.
The software giant explained at that time that the source of the problem was related to the number of installed network filter drivers. In Windows 7, the quantity of network drivers that can be installed cannot be larger than 14, with a default value of 8.
