How to upgrade from Windows7 Home Junior or Advanced to Windows7 Ultimate? Can I upgrade directly?

Such a problem, a bunch of novice friends are more concerned, look at the actual combat of a domestic user, everyone can increase the understanding, the following text begins -

A lot of people just bought a big A (here refers to the Shenzhou notebook, in fact, other books are also randomly given the same, even the MSDN version is also integrated) friends will or want to match the original machine The win7 base version is upgraded to the flagship version, or 32-bit, or 64-bit. In the past, someone introduced the method of online upgrade directly on the basic version. The method is simple, I tried it, but after the upgrade, the system is very unstable, there will be such undetermined problems, and the C drive is more than the clean installation. Account for 2-3 G. Some for clean installation, so go online to download, and look for ways to crack activation, in fact, you don't have to, the supplied Win7 CD can be directly installed 32-bit flagship version (Note: it is a direct clean installation of the flagship version, It is not upgraded after installing the basic version, and it is not required to crack, directly activated genuine!) The installation process is very simple, no need to engrave the disk, and no other auxiliary software, can be installed directly through the hard disk, the specific steps are as follows:

1. Put the random win7 system disk into the CD-ROM drive (note: don't open or run the CD-ROM drive), open the “Computer” window, select the CD-ROM drive (do not need to open it), right-click and select “Copy”, then Paste the "optical drive" into the root directory of any hard disk other than the C drive, such as the E drive (the following is the E drive as an example). After copying, you can see a "CD_ROM" file in the root directory of the E drive. Folder, change its folder name to "win7", enter the folder, delete the "EI.CFG" file under the "SOURCES" folder.

2, remove the CD, restart the computer, press F8 before entering the system (ie press F8 in the Shenzhou logo interface), enter the system menu, select the top "Repair the computer", the system read and install interface will appear - "Select language (select keyboard input method) - "Select user name, password", both "OK" or "Next", then enter the "System recovery options" "Interface, then you must select the bottom option "Command Prompt", a DOS input window will appear, enter "E:\\WIN7\\SETUP.EXE" under the cursor of the window (such as copying the "CD-ROM" disk is not E disk, please change your drive letter), then enter, then the win7 installation interface will appear, if it does not appear, please check the previous steps are correct.

3, click on "Now After the installation, the "Version Selection" window will appear, definitely choose the flagship version, then the "terms", tick "Next", "What type of installation do you want to make" select "Custom (Advanced)" , "You want to install windows In the "Where" window, select "C", click on the "Drive Options" at the bottom right of the window (important, certain points);

4, (If your big A's hard drive has been re-zoned, and already Delete the 100M reserved (hidden) partition of win7, you don't have to go through this step, go directly to the next step. Click "Delete" to delete the "Reserved Partition" and "C" partitions, ie the first and second partitions, delete the partition Be sure to be optimistic, do not delete the partition with copy win7, otherwise it will not be installed. Click "New", "OK", it is best not to adjust the capacity of the partition, regardless of the prompt. There is still a reserved partition of 100m after the new

5. Select the "C" partition (the second partition with the reserved partition, the first partition without the reserved partition), click "Format". This step is very important, otherwise it will be retained during installation. Your original system. The reserved partition does not need to be formatted. After the formatting is completed, click “Next” to enter the formal installation file. The process of installing from the hard disk is very fast, much faster than the CD.

6 About activation: The installation of the new system is very simple. Right click on the “Properties” of “Computer”. In the bottom line of the window that comes out, click “Replace Product Key” and enter the flagship OEM of any type of machine you are looking for online. The key can be activated. After activation, you can see if it is actually activated!

Finally, say a few words:

1. Win7 system disk should be the same number of bits (32 bits) Or 64-bit), no matter what version is the same CD, but the EI.CFG file is different, you can use Notepad to open the file to see. In addition, the big A disk to remove the EI.CFG file After the installation, you can only install the home basic version. It is estimated that the OEM file on the disk is restricted, so you should not use the hard disk to install it directly.

2. Regarding whether the 100M reserved (hidden) partition of Win7 is removed, you can search on the Internet and decide on your own. I removed the hidden partition.

3, how does the big 4G memory play a full role in the 32-bit system? I am not in favor of cracking memory with 4G software, which will cause system instability.

The principle of other brand machines is the same, this article is only for technical exchange and reference.
