Win7 system version installation needs to pay attention to what matters

        In the process of using the computer, especially in the process of the notebook, it is likely to encounter the version of the problem, and this also makes some white people feel a headache, and the so-called win764 pure system and 32-bit system upgrade It is a headache, so this will bring a guide to the 64-bit operating system.
1, using a 64-bit operating system, the memory must be higher than 4G, which is also because the 32-bit operating system can only recognize the memory below 4G, even if there is a patch, it can not achieve a stable memory call To the extent, it is recommended that friends above 4G memory use a 64-bit operating system, which is beneficial to the maximum use of the system. In fact, in the 64-bit operating system will get better performance development, although the stability of 64-bit system has been questioned in the previous period, but in the future, with the continuous improvement of computer memory, 64-bit operating system will also Become the mainstream.
2, 64 bit is backward compatible, but in some cases, it is best to use the same system digits of software, so compatibility and stability is much higher than the same version The operating system, at the same time, you should also pay attention to the 64-bit driver is not compatible with the original 32-bit, and many software is also incompatible.
3, before upgrading (installing) the 64-bit system, some files and drivers in the original system must be backed up in time to prevent tragedy, and you can not directly upgrade the 32-bit operating system to 64 Bit operating system, because the architecture of these two systems is completely different.
4, about Windows7 in the 32-bit to 64-bit system, you must not be wrong with the system disk, one is X86, one is X64, if you delete the wrong file, there will be some system running problems, of course 32-bit and 64-bit systems can coexist on the same computer, but users need to separate the system disk, otherwise it will produce the tragedy of system file coverage.
