According to foreign media reports, Windows 7 is faster than Windows Vista in the same hardware environment, but the RC version of Windows 7 is no better than the beta version.
After testing, Windows 7 RC starts quickly, especially if you have a WDDM1.1 driver installed, your computer will not slow down even when multiple windows are open.
Next, let's take a look at the installation and performance of Windows 7 RC:
Performance: By default, RC has a full set of features that can work well in modern home and office computers, and is an excellent environment for running applications.
The installation process is faster: if you need to manually modify the configuration files, you can upgrade the installation, however, the file transfer time spent upgrading the installation is much longer than the net installation.
Installation: Microsoft recommends that users perform a net installation of Windows 7 RC and, of course, you can upgrade from a beta version to an RC.
