The users who have installed win7 are naturally a lot, but there are not many users who upgrade to sp1. The reason is that sp1 is not installed frequently, but if you still want to install it, you can install it because there is a solution now. User-sharing installation process:
Yesterday morning, the SP1 package was upgraded. Unfortunately, at the beginning, like many people, the lack of components was due to the system used by the optimization master. SP1 cannot be installed without an alternate driver. Later, the spare driver in the top post was removed and skipped over. Installation is possible. However, by the end, there was an error that the path could not be found. Unable to configure SP installation failed. Error code: 0x80070002. ERROR_FILE_NOT_FOUND (The system cannot find the specified file).
After that, I tried installing [System Update Preparation Tool for Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2] (Patch No.: KB947821) Microsoft Official Link: support.microsoft.com/Kb/947821/zh-cn There are multiple versions for download. A toss. Still failing. The error description has not changed as it is. . . . . . . . . It lasted for a long time, and there was no solution in the jar. I was ready to give up SP1. Because I really don't want to install the system.
Reason for failure analysis :,, the reason for the path not found. . I guess. Really, we are all over-optimized. The system information registry information is incomplete and has been cleaned up. This causes SP1 to fail to complete the backup and restore the registry. . There is also a conflict between patches that have been blocked for patching or that are not installed.
Tucao: Many people say that they have to reinstall the system. It is indeed possible to reinstall the system more proficiently and thoroughly. Only then will there be a download and installation process for most commonly used software. Moreover, all files of system disk C will not be guaranteed, and important files must be backed up. Time adds up. . . It is also troublesome.
So, if you want to keep the C drive, don't want to download and install various software. If you don't want to backup and upgrade the hardware driver. Still assured of upgrading.
Finally, desperately, the system CD upgrades WINDOWS. This is my last chance. If you fail, you can't figure it out.
The method is as follows.
1. Prepare the windows7 genuine CD or download the CD image. I used the downloaded image no problem. I use this version (cn_windows_7_ultimate_x86_dvd_x15-65907.iso) under the soft media (Windows7 official retail version (Microsoft official CD original) download Daquan), pay attention to the X86 X64 version just fine.
2. If there is a CD, the disk will be inserted. If there is no disk, the virtual CD-ROM will load the image. If there is no automatic play, enter the disc to run the setup.exe.
3. Installation - because you are already a win7 system, so this is not a real installation, but a system upgrade. It will prompt you to upgrade the network, and see the prompts all the way to continue. It is good to skip when you need the serial number, and choose to activate the network.
Explain: This upgrade is similar to system restore. The main effect after upgrade is as follows
1 All installed system patches are automatically uninstalled (initial state, this does not care, because after installing SP1 All the patches will be integrated, and it will be better to remove them here.)
2 In addition to the default language exception, all installed system language packages are automatically uninstalled (nothing, you need to install SP1 yourself)
