To use a 64-bit version of Windows Vista, you must meet the following two conditions:
1. The computer must have a 64-bit processor;
2. A 64-bit device driver must be provided for devices on the computer.
Precautions for installing 64-bit Windows Vista
1. One or more devices in the computer may not have 64-bit device drivers;
2. The device driver must undergo a digital signature;
3. 32-bit device drivers are not supported;
4. 32-bit programs may not be fully compatible with 64-bit operating systems;
5. It may be difficult to find programs for 64-bit operating systems;
6. Not all hardware devices are compatible with 64-bit Windows Vista.
Advantages of installing 64-bit Windows Vista
1. Improved memory support, and allowed the addressable memory space to exceed the 4 GB limit in 32-bit operating systems;
2. Improved the performance of programs specially designed for the use of 64-bit operating systems;
3. Enhanced security features.
The main differences between Windows Vista 32-bit and 64-bit versions are related to memory accessibility, memory management, and enhanced security features. Windows Vista 64-bit version has the following security features:
1. Kernel patch protection;
2. Support for hardware-based data execution Protection (DEP );
3. Force the driver signature;
4. The support for 32-bit drivers is canceled;
5. Support for the 16-seat system is canceled;
When using 64-bit Windows Vista, one of the biggest advantages is that it can access more than 4 GB of physical memory (RAM ). This kind of physical 32-bit Windows Vista cannot be addressable.
Based on the installed Windows Vista version, 64-bit Windows Vista supports RAM from 1 GB to 128 GB or more. This ability to address larger physical memory enables Windows Vista to minimize the time required to swap processes with physical memory. Therefore, Windows Vista can manage processes more effectively. This memory management function helps improve the overall performance of Windows Vista.
