After Windows 7 was installed, the download instructions show Windows 7 build 7600.16385. But how can we view this version number in win7? After searching online for half a day, I found this method to view the detailed version number of win7. You can use slmgr. vbs to view the detailed win7 version number.

Generally, you can enter "winver" in the running column to view the version. However, only the words 6.1 (build 7600) are displayed, and the detailed version number behind 7600 cannot be viewed.



To view the detailed version number of Windows 7, run another command: slmgr. vbs: Enter slmgr. vbs, you can see the usage of this command and various parameters, I have done a few, as follows:

1. slmgr. vbs-DLI

Display: operating system version, some product keys, and license status

2. slmgr. vbs-DLV



Display: the most detailed activation information, including: Activation ID, installation ID, activation deadline

3. slmgr. vbs-xpr

Display: whether to activate it completely

4. slmgr. vbs-IPK

Change win7 serial number

5. slmgr. vbs-ato

Activate win7

It cannot be activated directly. Although you can activate it by phone, it is troublesome. More people are on the Internet when installing the system.
Activate the key. If you are lucky, you can activate it directly. The next time you install the system, you will find that the key fails to be activated, and you will need to find a new key that can be used.
