How do I upgrade from the Windows 7 Home Starter or Advanced edition to the Windows 7 flagship? Can you upgrade directly? Such a problem, a pile of novice friends are more concerned about the domestic user to see the actual combat, we can understand, if interested in the words to do, The following officially started Windows7 upgrade flagship version of the actual combat.

To a lot of just buy big A (here refers to the Shenzhou notebook, in fact, other books have random gifts are the same, and even the MSDN version is also integrated with the friends will or want to the original computer with the Win7 version of the upgrade to the flagship version, or 32-bit, or 64-bit. Someone has previously introduced a direct online upgrade on the basic version of the method is simple, I tried, but the system is very unstable after the upgrade, there will be such an uncertain problem, and C disk than a clean installation of 2-3 more G. Some for clean installation, so go to the Internet to download, and look everywhere to crack the activation of the method, in fact, can not be, random comes with the Win7 CD-ROM can be directly clean installation of the flagship version of 32 (note: Direct clean installation of the flagship version, not the installation of the basic version after the upgrade, and is not required to crack, direct activation of the)

Installation process is very simple, do not need to carve, and do not need other auxiliary software, directly through the hard disk can be installed, the specific steps are as follows:

1, will randomly send the Win7 system disk into the optical drive (note: Do not point to open or run the optical drive), open the Computer window, select the optical drive (not required), right-click Copy, and then paste the CD-ROM into the root directory of any hard drive except C, such as E disk (for example, e-disk below), After copying, you can see a "cd_rom" folder in the root directory of e disk, change its folder name to "Win7", and enter the folder, "SOURCES" under the "EI" folder. CFG "File deletion.

2, remove the CD-ROM, restart the computer, in front of the system press F8 (that is, under the Shenzhou logo interface press and hold F8), go to the System menu, select the top of the "repair computer", then the system read and install interface-"Select the language (select the keyboard input method)"-"Select User name, password", are "OK" or " Next, and then go to the System Recovery options interface, then be sure to select the following option, "Command prompt," and a DOS input window will appear under the window's cursor, "E:win7setup." EXE "(such as copy" optical drive "disk is not e disk, please change to your letter), and then enter, then will appear Win7 installation interface, if not appear, please check the previous steps are correct.

3, after clicking on "Install Now", will appear "Version Selection" window, it must be the flagship version, then the "terms", tick "next", "What type of Setup do you want to install" select "Custom (Advanced)", "Where do you want to install Windows" window, select "C", Click on the "Drive Options" (important, certain points) at the bottom right of the window.

4, (if your big A's hard disk has been repartition the area, and has already removed the Win7 100M reservation (hidden) partition, do not have to take this step, directly to the next step). Click "Delete", delete the "Reserved Partition" and "C" partition, that is, the first and second partitions, delete the partition must be optimistic, do not copy the partition has Win7 deleted, otherwise it will not be installed. Click "New", "OK", it is best not to adjust the capacity of the partition, do not tip. There are still 100m of reserved partitions after the new one.

5, select the "C" section (with a reserved partition for the second partition, no reserved partition for the first partition), click "Format." This step is important, otherwise the installation will retain your original system. The reserved partitions do not need to be formatted. After the format is complete, click "Next" to enter the process of the official installation file. The process of installing from the hard disk is very fast, much faster than the disc.

6, about activation: The installation of a new system activation is very simple, right-click the "Computer" of the "properties", in the window out of the bottom line, click "Replacement Product Key", input online to find any model of the machine's flagship OEM key can be activated, after activation you can see if it is really activated!

Finally say a few words:

1, Win7 system disk as long as the same number of (32-bit or 64-bit), no matter what version is a same CD-ROM, but the inside of the Ei.cfg file is different, you can use Notepad to open the file to see know. In addition, the large a disk removed ei.cfg file and then carved disk. In the installation can only install the home base version, it is estimated that the OEM file on the disk limit, so we do not go to carve, directly with the hard disk installation.

2, about the Win7 of the 100M (hidden) partition is removed, we can search on the Internet, their decision, I was the hidden partition removed.

3, large A of 4G memory in the 32-bit system to fully play a role? I am not in favor of using 4G software to crack memory, which will cause system instability.
