Solution:
1. Prepare genuine windows7 CD or downloaded CD image. I use the downloaded image. No problem. I use this version (CN _ Windows _ 7 _ Ultimate _ x86 _ DVD _ x15-65907. ISO) as a soft medium (download the complete set of official retail version of Windows7 (original version of Microsoft official CD)), so just pay attention to X86 X64 version.
If you have a CD, insert it. If you don't have a CD, just load the virtual cd into the mirror. If it doesn't play automatically, please enter the CD and run setup.exe.
3. installation-because you are already a win7 system, this is not a real installation, but a system upgrade. It will prompt you to upgrade your network. Just read the tips all the way and continue. Just skip the serial number when necessary and select networking activation.
Note: This upgrade is similar to system restore, and the main effects after the upgrade are as follows.
① All installed system patches are automatically uninstalled (in the initial state, don't care about this, because all patches will be integrated when SP 1 is installed later, so it is better to uninstall here. )
② Except the default language accident, all installed system language packs are automatically uninstalled (no way, you have to install SP 1 and do it yourself).
I need a lot of temporary space on the system disk C, but I don't know how much. Anyway, I probably had a spare C drive of 10G.
④ Users who use WIN7 pirated soft activation should pay attention. After the upgrade, the soft activation is invalid and needs to be reactivated (I am one of them. . . Um ... Khan)
⑤ The cracked theme system is invalid (it will be broken later, and there are masters and Rubik's Cube. )
Most importantly, this upgrade method saves all registry information and system settings, software settings and hardware drivers, and has not changed. In other words, by restoring the system in this way, all drivers don't have to worry that the failure will not affect the use of any installed software. Even if it is a software program installed on disk C, there will be no abnormality or setting change. There is no problem with the pro-test. The greatest comfort. )
Ps: It takes a lot of patience, thinking that the upgrade process is very slow and long. Restart several times.
After entering the system, more than N system vulnerabilities were found. Don't worry. Because all the patches have been removed. Turn off automatic system update and upgrade of WIN7.
4. If the system becomes inactive, it should be activated by soft program. It is recommended to activate it by skpatch V2beta 1.exe. ..
5. Just install SP 1.
