Difficult process of upgrading Windows 7 flagship Edition

I bought a Sony notebook last Sunday. Because the preinstalled Windows 7 Family Basic edition has many functional limitations (such as the most dazzling aero effect), you must upgrade it to the flagship edition.

I used XP all the time before. I also saw win7 installed on my friend's notebook, which is also the flagship version upgraded from my basic family class, in addition, it is OK to simply enter a key that has been searched from the Internet. However, we encountered a lot of trouble during the upgrade process.

I followed the upgrade instructions on the Internet (in fact, it is a few simple steps), entered the key (at this time there is no message about the key error), click the upgrade encounteredFirst question, You need to enable system restoration for the partition where the system is located. Click the link to bring up the windows help system, prompting you how to perform the operation. However, after clicking "Configure", the system prompts "incorrect file name, directory name, or volume label Syntax". Google, you need to enable the block level backup engine service and Windows Backup Service (you may know what the name means, at least I solve this problem ), repeat the operation to enable system restoration for system partitions.

The system shows that the system is being upgraded. After several minutes, the system will restart. "Windows Update is being configured" is displayed before logon. After a few minutes, the system prompts "failed to configure Windows Update, restoring changes ...". This isSecond questionIs also the most important and tricky issue. At first, I thought the key was incorrect. I found a few and tried it several times. After I entered the key, I did not prompt a key error. I updated the configuration after I restarted it, if you are not sure about the number of %, the system prompts a failure and restores the change. This problem was fixed for one night, and no solution was found. Repeated restart (it took several minutes to fail to configure Windows Update ), I am not in the mood to upgrade. I want to try it out first. I did some other things the next night and thought about it again after I got idle. I can't do it without upgrading the flagship version. So I continued to search online, but it still didn't work.

In the daytime, when there were not many tasks, we made full use of the time to continue searching. From the previous two days, we can see that: 1. After the key is entered, no error is prompted; 2. Because the computer was just bought, the system version is old, these two days after the machine is automatically updated, the shutdown is displayed in the installation of updates, and then started is the same result as the previous -- "Windows Update Configuration failed, restore changes... ". That is to say, the key should be correct, but it should be due to the current reasons of the system, resulting in Windows automatic update cannot be installed successfully. To successfully upgrade Windows 7 flagship edition, you must first solve the problem of "failed to configure Windows Update.

So along this line of thinking, I focused on this issue. Continue to Google, and there are more than 70 thousand results found. Microsoft's official answer search also has over 140 records. Because I was in the office during the day, I couldn't try it one by one. I recorded it first. I went back to the office for a while and finally succeeded.

The possible cause is that the software installed in the system affects system updates.

1. Try to clean the startup (refer to here) to prohibit all third-party software andProgramStart the system at startup, and select F8 to enter safe mode during startup to install and update. In addition, it is best to uninstall installed anti-virus software such as anti-virus software, because they may prevent updates and installation, and they can often be started in security mode.

I tried it like this (including uninstalling and killing software) and failed. Please continue.

2. If the problem persists after the clean startup, try the following methods to update the component.

Please download and install the following program: http://go.microsoft.com /? Linkid = 9665683

Select "Run aggressive option" during installation (this option resets the updated component ).

Restart your computer and then download and install the following patch again: Windows 7 system update preparation tool (kb947821) package (http://support.microsoft.com/kb/947821 ). Please read the instructions on this page briefly, mainly because the installation process may be slow and there are symptoms of "false death". Do not turn off urgent children's shoes. When downloading, select 32-bit or 64-bit.

Restart the computer again.

Updates that have been automatically downloaded before installation can be successfully updated. I think it is okay to upgrade the flagship version. So I entered Sony's OEM flagship key and finally successfully upgraded it to experience the "glass" effect.

Postscript:

1. If a key fails to be entered, you cannot enter a new key again. You can open the registry, search for the key, and delete the key. When you run Windows anytime update again, you can enter the new key.
