It is worth mentioning that Microsoft began to quote the concept of SKU from Vista. The practical significance of the so-called SKU is that the retail version of Vista installation media contains five ordinary versions (entry version, home basic version, home advanced version, business version and flagship version). When installing the system, judge and select the version according to the product key input by the user, and install the components of the corresponding version. This is convenient for users to choose between multiple versions without new installation media, but it is also convenient for piracy, cracking and upgrading. Since 20 10/22 October, the retail boxed discs of Vista will no longer be sold, but computers pre-installed with Windows Vista can still be purchased before 20 10/22 October, and the mainstream support will continue until 20 12.
Main disadvantages:
1. Poor compatibility.
Consume resources
3.UAC is useless and redundant
4.Vista is a transitional product, and Microsoft is eager to develop Windows 7.
5.Vista runs very slowly.
6.Vista requires too much hardware.
