FLAME--A new cyber threat

Overview of WINDOWS 8

If you have been following all the good press around Windows 8 and are waiting to try it on your own computer, here’s the good news. The consumer preview version of Windows 8 (just a fancy name for beta software) is now available for download and it is very likely that your existing system specs are good enough to run Windows 8.

The System Requirements for Windows 8

According to the Windows 8 FAQ, any machine equipped with 1 GB of RAM, 16 GB of hard disk space and 1 GHz processor should be able to handle Windows 8. The minimum RAM requirements are 2 GB in case you would like to install the 64-bit version of Windows 8.

Should you download Windows 8 Setup or the ISO Image?

As you may have noticed on the Windows 8 download page, the installation of Windows 8 can be done in two ways.

You can either take the easiest route and download the Windows 8 Setup program – that’s also the default option.
Alternatively, you can download ISO Images of Windows 8.
If you are planning to install Windows 8 on your existing computer, either on a different partition (dual-boot) or just want to upgrade an older version of Windows to Windows 8, the default Setup program is a good choice.

Please note that that your installed software program will only be preserved if you are upgrading from Windows 7 to Windows 8. If your planning to install Windows 8 on top of Windows XP or Vista, only the files will be preserved but not the various software programs that you may have on the disk.

The ISO image may be more handy in other situations like:

Your computer has an x64 processor but is running the 32-bit version of Windows. If you want to install the 64-bit version of Windows 8, download the 64-bit ISO.
You have an iMac or MacBook and want to install Windows 8 on the Mac using Boot Camp software.
You want to install Windows 8 on multiple computers. Download the ISO, create a bootable DVD and boot the other system using this Windows 8 disk.
You want to run Windows 8 as a Virtual Machine inside your existing copy of Windows.
You are running Windows XP.
The universal product key for Windows 8 is NF32V-Q9P3W-7DR7Y-JGWRW-JFCK8.

Will my software programs run inside Windows 8?

Before grabbing the ISO image of Windows 8, quickly run this setup utility and it will show a list of all software programs and hardware drivers on your system that are compatible with Windows 8. Else you can visit this page to see a list of all known software that are found to be working with Windows 7.

What route should you take?

You can have Windows 8 on your computer in three ways – you can install Windows 8 side-by-side (also known as dual-boot), as a virtual machine (so that it runs inside your existing Windows just like any other software) or Windows 8 can be your main OS (there’s no going back then).

If you just want to try out Windows 8 but without disturbing any of your existing set-up, the safest bet is to use a Virtual Machine. If you have a vacant partition or don’t mind creating one (it’s easy), go for the dual-boot option. Else, if you have a spare computer, you can consider upgrading to Windows 8 overwriting the previous installation of Windows. Good luck!

How to Unlock a Computer Without a Password Reset Disk

A locked computer can result in dead end frustration, potentially costing hundreds of dollars in repair bills. Unlocking your computer without the aid of a password reset disk can be done by accessing the default Administrator account from Safe Mode and unlocking your computer via console commands. This can generally be done in minutes.


    • 1
      Restart the computer.
    • 2
      Press "F8" as the computer is booting and select "Safe Mode."
    • 3
      Click on the "Administrator" account.
    • 4
      Select "Start" and click "Run."
    • 5
      Type "control userpasswords2" and press "Enter."
    • 6
      Uncheck "Users must enter a username and password" and restart the computer. It will be unlocked.

      Google has designed Chrome OS keeping the Web in mind and most of its functionalities will be available only if the Chromebook is connected to the internet. Users apps, games, photos, music, movies and documents will all be on cloud.

The bare-bones operating system is essentially a Web browser that will guide users to applications like email and spreadsheets directly on the Web, instead of storing software such as, say, Outlook or Word on PCs.

Moving day-to-day functions onto the Internet removes the burden of time-consuming tasks associated with traditional PCs, like installing software and updates, backing up files and running antivirus checks.

As also mentioned before, everything is on the cloud. Hence the laptops will be tightly integrated with Google's "cloud" online services, and will have almost no capacity to store information. Though they will have slots to plug in other storages device users buy separately.

As with the company's mobile OS Android, Chrome software will be free.

Samsung Electronics Co and Acer Inc made the first Chromebooks.Both models will have keyboards, but no hard drives for storage. The machines will be like computer terminals dependent on a connection to the Internet. The laptops come with 16 gigabytes of flash memory -- the kind found in smartphones, tablet computers and some iPods. Google Chromebooks will run on Intel Corp's Atom chip.

While Google has diligently worked to make sure Chromebooks can be used offline, the computing model ultimately relies on being connected to the Internet.

The company claims that Chromebooks will be up and running in about eight seconds. Every time a user will turn it on, the software will check online to see if there are updates, and it will always boot up with the latest version.

In case, there's a failure, for whatever reason, the OS will simply reinstall itself.

Google Chromebook comes with security features such as secure tabbed browsing (called sandboxing), data encryption, and verified boot. According to Google, "Chromebooks have many layers of security built in so there is no anti-virus software to buy and maintain

Synchronize Files Easily With Window's Briefcase

Briefcase can either store your shared data on a USB flash drive or other portable storage device, or move your files between, say, a desktop PC and a laptop via a network. Unless you edit the files directly in the briefcase, you can sync a briefcase with only one other system.
To set up a briefcase to work with a USB thumb drive, insert the device into a USB port, open Windows Explorer, and select the drive. Right-click a blank spot in the window, choose New, Briefcase, and give the briefcase a name. Double-click the briefcase to open it, click Finish in the useless wizard, and then drag the files and folders you want to sync into the briefcase. Close Windows Explorer and properly remove the USB drive.
When you use these files on another PC, don't put them on the hard drive. Instead, just insert the USB drive, open the briefcase in Windows Explorer, and then use the files as you normally would.
When you return to the first PC, insert the USB drive, open the briefcase in Windows Explorer, and click Briefcase, Update All (in Windows XP, just right-click the briefcase and select Update All). A dialog box will display the files that don't match between the briefcase and the hard drive, and it will show you which items should be replaced with which. If you disagree with an action, right-click the file to change its options. When you're satisfied, click the Update button (see Figure 1).
You can sync the briefcases on a notebook and a desktop PC if the systems are networked: Create a folder in the notebook's My Documents folder called Holds Briefcase, right-click it, selectSharing and Security, click Share this folder, check Allow network users to change my files, and clickOK. On the desktop PC, create a briefcase in the notebook's Holds Briefcase folder.
Use the files in the notebook's briefcase. When you connect it to the network, sync the briefcase as described above, using the notebook as the flash drive.

Rip Music Off a DVD

Is there a way to rip audio from a DVD onto a PC? I record songs to tape, and from there to a PC.
Tommy Kikuchi, Woodside, New York
Unfortunately, the Digital Millennium Copyright Act calls into question the legality of convenient DVD rippers such as Handbrake. But I know of a better solution than recording to tape first (and it's legal), although because of a DVD's copy protection, it still entails some loss of sound quality. Simply connect one end of a stereo audio cable to your PC's Line Out jack (where you plug in the speakers) and the other end to the PC's Line In jack (where you attach the tape player or turntable). This requires a stereo audio cable with one-eighth-inch miniplugs on both ends. If you don't already have one, you can buy such a cable for less than $5 at any electronics store.
Once you're connected, rip the music with your choice of recording software. The PC will be silent until you plug the speakers back in, but your recording program's VU meter will tell you that there's sound. Remember that selling or giving away your digital recordings of any copyrighted material is illegal.

Fix Microsoft Word's Double-Digit Numbering Glitch

Microsoft Word's numbering option (for numbering lists and paragraphs) works wonderfully until you reach 10. The double digits mess up the indentation after the numbers because the extra digit pushes the text to the next tab setting. The result: ugly. To fix the spacing, move the first tab--along with the hanging indent--a bit to right. Highlight all of the ugly, numbered text, and select Format, Bullets and Numbering. Click the Customize button. Increase the setting slightly for the 'Tab space after' and 'Indent at' fields. These two fields should have the same number--0.7" will probably do. Finally, click OK.
