Win7 on how to install and upgrade the purchase of 7 questions (1)

Microsoft's latest operating system Windows7 officially released, we have some answers to the most concerned questions of netizens. Most of the questions are about how to install and upgrade the purchase.

I received a lot of e-mails, are asking questions about the Windows7. So I think it's time to share the most common and interesting questions and answers. If you have more questions, or if you want to talk about your own ideas, please post a comment after this article.

1 # Q: If I replaced the 64-bit version of Windows7, my 32-bit applications can use it?

A: The application can be run. But for system-related software, such as hardware drivers and anti-virus software, you need a 64-bit version. Keep in mind that 32-bit plugins cannot be used on 64-bit applications. The biggest example is Flash, which is hard to believe, but Adobe has not yet released a 64-bit version of the IE plugin, so to browse Flash-based web pages, you need to run a 32-bit browser.

2 # Q: netbooks do not have DVD drives can be installed Windows7 it?

A: Yes. You can download the operating system image file and then install Windows 7 on your netbook using a USB flash drive. U disk must have 4GB or more storage space, you need to delete other content. If you are familiar with the command line, you can use Diskpartutility, but most people will like to use the fool-like Windows7USB/DVDDownloadTool. As the name implies, the tool will also create a bootable DVD that you can install as if you were buying an installation CD in the store, but if you don't want to go out and buy an external optical drive, it's useless.

3 # Q: What Windows7 upgrade and buy a new installation is the difference?

A: I did not know why anyone would want to buy a new installation Windows7 it? If your computer is already running Windows XP or Vista, you should upgrade. If you are planning on a new system from parts, you can get a cheaper OEM version. So who needs a "new" version? The only thing I can think of is that those who want to run Windows 7 with BootCamp on the Mac, those who use Linux or older versions of Windows like Me, 98 or even 95. (In fact, the last category of people most of all the change the hardware)

In fact, the upgrade and new installation is the same. The difference is, what happens to your system: If the upgrade installer does not find an active Windows XP or Vista installation on your machine, you will not be able to complete the installation.
