Windows 7 SP1 cannot install 100% what to do

1, why the installation of Windows 7 SP1 official version of the prompt "system is missing the necessary components" and caused the installation can not?

2, why install the Windows 7 SP1 official version When prompted "The system can not find the specified path"?

3, why install Windows7 SP1 after reboot after the "configuration error" and other issues (unable to configure SP installation failed.) Error code: 0x80070002. Error_file_not_found (the system cannot find the specified file)?

In fact, since the release of the official version of Win7 SP1, the company has been looking at the root causes of these problems, and is seeking a good solution.

The root causes of such problems, and the use of Win7 optimization master, Rubik's Cube, and other software to clean up the "system-driven backup" this relationship, through the January 16 Sunday of the full day of the investigation, identified and C:windowssystem32driverstorefilerepository The folders under this folder are related to ATIILHAG.INF_AMD64_NEUTRAL_0A660E899F5038A2, atiriol6.inf_amd64_neutral_bde34ad5722cca75, etc. Deleting these folders prompts Win7 SP1 to install "the system lacks the necessary components." At the same time, because restoring these two files will also result in "system cannot find the specified path" and so on, the solution is only to restore those driver backup files. By manual recovery because it involves file permissions and 32-bit, problems with 64-bit systems are more complex to fix for primary users, so in this article we recommend that you use a different method of not reloading the system and keep all the software and configuration installed-that is, using the Win7 disc to repair the system.
