repper Jessi 王嘉尔:Window Vista

本人最近下了一个测试xp能否升级为vista的软件,可测试结果是英文,如下:
We're sorry, but your PC cannot currently install and run the core experiences of Windows Vista.
However, you may be able prepare your computer for Windows Vista by upgrading your PC hardware.
You will need to take the following actions to run Windows Vista.

Additional hard drive storage

15GB free space required (Your computer currently has 4.04 GB)
You will either need to:
a) upgrade your hard drive to increase its capacity, or
b) create additional free space on your existing drive by removing unwanted files.
If you decide to upgrade your hard drive, we recommend 40GB capacity at minimum for premium editions of Windows Vista. Contact your PC retailer to see if an upgrade is available.
Upgrade your hard drive controller

Your Hard Drive controller does not currently support Windows Vista
No Windows Vista driver could be found for your system's hard drive controller. You should not upgrade this system to Windows Vista unless you are able to first upgrade your hard drive controller or obtain a suitable Vista driver for your existing hard drive controller. Contact your PC retailer to see if an upgrade is available.
