Generally for mirror files, if the use of WinRAR to face the ISO file, in fact, there is the process of decompression, if it is a large file, it will have to wait for a long time. So we are using the virtual optical drive software to install. But since we have win8, we don't have to find a virtual CD-ROM to install the software, because the WIN8 is already built.
1, we can the ISO and other mirrored files directly right button, and then click Load.
1. Browse the disc image and extract the files directly

Our people now basically use computers, everyone will be in the Win7 flagship computer watching the Web page watching TV, there are many uses, although the computer has a DVD function, but the basic users will rarely use these features, we will feel that this function is useless, watching video can also be viewed directly on the Web page, But we still need to see some tutorials users need to use this feature, we insert the disc will find that the optical drive can not read the phenomenon of no r
Let's share with you today the specific steps and methods of the Windows7 CD installation tutorial.

This is tested with the platform Core E8400 processor, ASUS X48 video card, 4gb/1600 memory and ASUS GT240 graphics card.
The start of the test time to enter the BIOS to adjust the boot after the start to save the restart start timer, until the beginning of the Windows7 desktop, the error in 5 seconds. (PS: Use u disk installation, when the system first reboot must be in the BIOS inside the first boot to the HDD, otherwise the system will be unlimited implementation of U disk installation.) )

A virtual optical drive is a tool for simulating (cd/dvd-rom) work, you can generate a CD image that is the same as the one you installed on your computer, and it works by first virtual one or more virtual optical drives, storing the applications on the disc, mirroring on the hard disk, and generating a mirrored file for the virtual CD drive. , and then you can put this mirrored file into the virtual CD drive to use.

For future use, I would like to carve a CD-ROM.
The problem is, 900M capacity can not be engraved.
If the compression package directly engraved on the CD, in the future use, and then slow decompression ... A
