At present, many brand-name machines and laptops are pre-installed with win7, and most computers are installed with the home or home advanced version. Although it is easy to use, however, upgrading is required to break through some functional limitations. It is said that the pirated system cannot be upgraded. Therefore, if you are pirated, you can simply reinstall the flagship version.
It is very easy to upgrade. Just enter the upgrade key and perform one-click operations as follows:
1. Right-click the computer --> properties,
Then you can see
2. Click "Get functions of the new version of Windows 7", select the key, enter the key, and wait until the key is complete.
