By now, you have probability started hearing the buzz about Windows 8. Maybe it's the new interface, Metro, which brings touch screen ease of use and the simple tile look of the Windows 7 phone to the desktop. Or maybe it's the Metro apps, that with a connected Windows Live account, can be downloaded and used on any Windows 8 computer you login to. Or, my favorite, the improved multi-monitor options. But did you know you can try it out right now for free with the Windows 8 Developer Preview?

Now I have to warn you that the Windows 8 Developer Preview is a pre-beta version of Windows 8. Fun to play around with but in no way should you use it in a production environment. And remember that some of the features and/or functions may not work properly.

You can upgrade an existing version of Windows XP, Windows Vista or Windows 7. But be forewarned that you cannot uninstall this release. You can also create a multi-boot setup, with Windows 8 on a separate partition. I use Oracle's VirtualBox to run experimental operating systems like this. I downloaded to latest version and it already had pre-configured settings for Windows 8.

Here's a quote from the Windows 8 Developer website:

The Windows 8 Developer Preview is a pre-beta version of Windows 8 for developers. These downloads include prerelease software that may change without notice. The software is provided as is, and you bear the risk of using it. It may not be stable, operate correctly or work the way the final version of the software will. It should not be used in a production environment. The features and functionality in the prerelease software may not appear in the final version. Some product features and functionality may require advanced or additional hardware, or installation of other software.

Note: You can't uninstall the Windows 8 Developer Preview. To go back to your previous operating system, you must reinstall it from restore or installation media.

System Requirements

The Windows 8 Developer Preview works great on the same hardware that powers Windows Vista and Windows 7:

• 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
• 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
• 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
• DirectX 9 graphics device with WDDM 1.0 or higher driver
• Taking advantage of touch input requires a screen that supports multi-touch
• To run Metro style Apps, you need a screen resolution of 1024 X 768 or greater

Notes about installing the Windows 8 Developer Preview

A clean install is supported on all builds, but you can upgrade if you are installing a download without the developer tools. You will receive the full set of migration options when setup is launched in Windows. To dual-boot, you must first boot from media and choose an alternative partition.

One of the most useful items I use daily is keyboard shortcuts. Especially shortcuts that I can perform with just my left hand, allowing me to keep my right hand on the mouse. You can use keyboard shortcuts to open frequently used files, folders, and programs like File Explorer. Windows has a ton of built-in keyboard shortcuts (see links at the bottom of this article), plus you can create your own custom keyboard shortcuts. Here are my favorite left-hand keyboard shortcuts:

Press	To
+ E	Open My Computer / File Explorer
+ R	Open the Run dialog box
+ D	Display the desktop
+ F	Search for a file or folder (Windows 7 / 8.1)
+ S	Search for a file or folder using Cortana (Windows 10)
CTRL + A	Select all
CTRL + X	Cut
CTRL + C	Copy
CTRL+ V	Paste
CTRL + ALT + (KEY)	Custom keyboard shortcut (see below)

create your own Windows keyboard shortcuts

You can create keyboard shortcuts that use CTRL + ALT + (your choice of a key) for frequently used files, folders, and programs. You will need to have a shortcut to the file, folder, or program you want to open first. You can use an existing shortcut (on your desktop or the Start menu) or create a new one. Once you have a shortcut:

1. Right-click on the shortcut
2. From the context menu, click Properties
3. On the Properties box, select the Shortcut tab
   
4. Click inside the Shortcut key box and press the key in which you want to combine with CTRL + ALT

Note:
You can not use the following keys for keyboard shortcuts: ESC, ENTER, TAB, SPACEBAR, PRINT SCREEN, SHIFT, or BACKSPACE.

A while back. I wrote an article about creating panoramic images with Microsoft Image Composite Editor (ICE) and Photosynth. With ICE and Photosynth, you can create panoramic images and then upload them to the Photosynth website. But what if you wanted to upload them to your website? That's where HD View comes into the picture.

Microsoft HD View is a new viewer to display large images (gigapixels) across the internet. It allows you to create panoramic images for web pages that do not take a lot of bandwidth. When someone views the image, they are only downloading what is required for that view. It is only when they pan or zoom that more of the image is downloaded. HD View / Deep Zoom is now included in ICE, also as a stand-alone command-line utility, and (here's the best), a Photoshop plug-in.

So if you're a Photoshop user, you can now export those panoramic images that Photoshop can create directly to HD View / Deep Zoom format. The Photoshop plug-in is available in both 32-bit and 64-bit. Here's a quote from the HD View website:

About HD View
HD View is a new viewer developed by Microsoft Research's Interactive Visual Media group to aid in the display and interaction with very large images. The HDView development team included Johannes Kopf, Matt Uyttendaele, Howard Good, and Michael Cohen along with Jonathan Fay of the Next Media group.

Recent advances in camera and sensor technology and software for stitching images together has led to the creation of images containing billions of pixels (gigapixels). These images are often panoramic, that is, they cover very wide fields of view. Since monitors typically contain only one to two million pixels, it is only possible to actually see 1/1000th of such image data at once. Also, viewing very wide fields of view require unwrapping of an image projected onto a curved surface (think of a map of the world) which can cause distortions.

HD View leverages current graphics hardware to allow smooth panning and zooming as well as the viewing transformation described below.

HD View was developed with a number of goals in mind. It should:

• allow smooth panning and zooming on large images,
• only download enough data to create the current view (and possibly look ahead to the next), and
• always display the current field of view with an appropriate projection. This means that when zoomed way in you should be presented with a standard perspective projection providing a sense of immersion, and when zoomed out you experience a curved projection so that get a full overview of the scene. In between the projection should smoothly transition.
• Finally, it should be easy to create your own HD View content and present it to the world via the web.

The HD View plug-in currently supports all major browsers on the Windows platform. The first time that you visit a page with HD View content you will be prompted to install the HD View plug-in.

Note: This article was based on OpenOffice 3. Since this article was written, OpenOffice version 4 has been released. Click here to read the newer OpenOffice 4 article.

A client recently asked me if I knew of any alternative to Microsoft Office. As a firm believer in open-source software, I told him about OpenOffice.org 3 from Oracle. It is a complete office software suite with a word processor, spreadsheet, multimedia presentation, graphics, and database programs.

OpenOffice.org is Java-based and requires it to be installed. It is compatible with other commercial office software and can read/write various file formats. XSLT and StarOffice formats are supported, but you will need to choose the custom installation to enable these filters. You can also expand the functionality of OpenOffice.org by using third party extensions. And you can also export to PDF in all of the applications. And best of all, it's free.

Programs included in OpenOffice.org

Writer
Writer lets you design and produce text documents that can include graphics, tables, or charts. You can then save the documents in a variety of formats, including the standardized OpenDocument format (ODF), Microsoft Word .doc format, or HTML. And you can easily export your document to the Portable Document Format (PDF).

Calc
Calc is a spreadsheet application that you can use to calculate, analyze, and manage your data. You can also import and modify Microsoft Excel spreadsheets.

Impress
Impress lets you create professional slide shows that can include charts, drawing objects, text, multimedia, and a variety of other items. If you want, you can even import and modify Microsoft PowerPoint presentations.

Draw
Draw lets you create simple and complex drawings and export them in a number of common image formats. You can also insert tables, charts, formulas, and other items created in OpenOffice.org programs into your drawings.

Base
With Base, you can access data that is stored in a wide variety of database file formats. Base natively supports some flat file database formats, such as the dBASE format. You can also use Base to connect to external relational databases, such as databases from MySQL or Oracle.

Math
Math provides numerous operators, functions, and formatting assistants to help you create formulas.

OpenOffice.org 3 is available for Windows, Linux, and Mac operating systems. For more information on OpenOffice.org 3, please visit their website OpenOffice.org.

When it comes to computer repair, you have to a detective of sorts. And once in a while, I come across a really good mystery. I recently got an HP M7360N in the shop that would randomly freeze-up in Windows XP when you moved the mouse. It would run perfectly fine in Safe Mode. Maybe a bad driver?

A check of the event logs yields absolutely nothing, not a single error. I check Device Manager and find the hard drive controller listed under the Unknown category, even though it is correctly identified as an Intel controller. I uninstall it inside Device Manager and then scan for hardware changes. The hard drive controller reinstalls back into the Unknown category.

The system is still freezing up randomly when the mouse is moved. I tried a PS2 and USB mouse and got the same results with both. I disable all non-essential drivers and reboot with no change. I download the original and latest drivers for the system, trying all with no luck. Maybe a corrupt installation?

I create an image of the hard drive and then wipe it clean. Using the supplied recovery disks, I proceed to re-install the operating system and recovery partition. The system froze-up three times during reinstallation. But this time, the hard drive controller is under the correct category, IDE ATA/ATAPI controllers. It's starting to look like a hardware issue.

I run a few DOS-based utilities to test the memory, hard drive, etc. with no luck. I even try the HP recovery diagnostics. Every test I run tells me that there is nothing wrong with the hardware. Using the keyboard only in Windows, I can install another utility to test all of the motherboard components. I allow it to run for six hours, and the system passes every test.

The BIOS is the next place I look and find it's a few versions older than what is currently available for download. I download and install the latest BIOS version, and it still keeps freezing up randomly when the mouse is moved. I start searching the internet for clues.

After a few different search queries, I come across an article at Badcaps.net discussing symptoms of capacitor failure on motherboards, one being 'system randomly and frequently freezes'. I check the motherboard thoroughly and find no capacitors that look bad. I start checking the expansion (add-in) cards, and all at once, the mystery was solved.

There on the graphics card was a bank of capacitors that the tops were swollen.

The movement of the mouse on the screen was causing the graphics card to freeze-up. I re-assembled the system with a new graphics card, and the issue was gone. Another computer repair mystery was solved.
