The "RT" in Windows RT stands for RunTime. It is because Windows RT is designed to run on lower power ARM processor tablets. A smaller runtime version of Windows 8 will be used, hence the name. Windows RT won't have the power of a full Windows 8 capable Intel x86 processor computer. But the Windows RT models will be cheaper and capable of doing the same as iPads and Android tablets today.

Without doing anything special and without any warning, my Blackberry Bold 9000 showed a white screen (The White Screen of Death!!!) and the message:

If you need to access your SkyDrive from a Windows XP computer you cannot use the official Microsoft app, it is only for Windows Vista and 7. Instead there's a free third-party program that I've been using for a while and I've found it reliable:

Introduction
If you write instruction documents or you work on a help desk, you need to take screen shots and annotate them easily and quickly. Of course Windows has the standard functionality:

Press PrtSc (Print Screen key) to capture the entire screen
or
Press Alt-PrtSc to capture the active window

But what about the next step? Pressing the PrtSc key just puts the image into the clipboard and where do you save it? You can paste into a Word document - but really that is terrible, it is hard to see it and it inflates the size of the Word document greatly. If you are writing an instruction document then save your screen shot first, then insert it into Word, don't paste.

Somehow you really need to save the screen shot in an image format. But don't use Paint and save as BMP, you'll get a huge file. The best format for screen shots is PNG, you get a high quality image with a small size.

In effect it means there are a number of steps to getting a usable screen shot ready to use. What if you could reduce those steps?


Snipping Tool
Microsoft include a nice little program called Snipping Tool with Windows Vista and Windows 7. Learn more about it here:

Greenshot
If you are using Windows XP or you want to try something different, Greenshot is a good choice. When you press the PrtScn key Greenshot takes over, it allows you to capture a part of the screen, with or without the pointer included. It will be saved as PNG and opened in Greenshot where you can draw lines, arrows and write comments. Find out more here: http://greenshot.org/ and here http://getgreenshot.org/


Conclusion
I've been using Greenshot for a while now and the best thing about it is the speed at which you can capture a screen, save it as PNG and add arrows and other notation to it. If you have to quickly take screen shots to send to people for support, Greenshot is an excellent choice. I recommend you try it.

Problem
In Excel 2010, when you try to create a pivot table it give the following error message:
Data source reference is not vaild

Solution
Often this happens because you opened a CSV or other data file directly from another program.

Make sure you save your data file first, before you attempt to create a pivot table. It will work if it is a saved csv, xls, xlsx, etc.

Introduction
FreeFileSync is a small, simple program for synchronising the files in two locations. For example, if you store files on C: but keep a copy on a USB flash drive as a backup, you can use FreeFileSync to keep the files up-to-date in both locations! That's the advantage over just copying the files. Also, you don't copy all the files each time, you just copy the ones that have changed or that are new. For further explanation click here.

There are of course many file/folder synchronisation programs available, the choice is yours which one you chose. In this article we'll focus on FreeFileSync - more details can be found at: http://freefilesync.sourceforge.net/ 

As an example of using FreeFileSync, we'll synchronise the files from a folder on the C: drive to a folder on a USB drive (this could be a flash drive or an external hard disk drive). We will only cover the basics, this is just a guide to get you started with FreeFileSync.


Download
http://sourceforge.net/projects/freefilesync/files/

At the time of writing, February 2012, FreeFileSync is at version 5. I downloaded FreeFileSync_v5.0_setup.exe, it was about 10MB in size.


Install
Insert your USB drive.

Double click the setup exe file (FreeFileSync_v5.0_setup.exe)

Accept the license agreement

Click Portable - this doesn't install to your computer, instead it allows you to run FreeFileSync directly from your USB drive.


Change the installation path to your USB drive and folder name FreeFileSync. This is where the program files will be stored. In our example J:\FreeFileSync, see the screen shot.

Click Install


Simple Folder Synchronisation
After it has finished installing, in Windows Explorer browse to your USB drive and into the folder as shown in the image below:


Double click FreeFileSync.exe

It will ask you 'Do you want FreeFileSync to automatically check for updates every week?' - click No

On the left you'll see 'Compressed view' - just to make the screen easier to read, click the X in the corner of this box to turn it off.

At this point your screen should look like the following:


The FreeFileSync screen is split into two main columns; left and right. I've marked these in orange in the above screen shot.

In the left box type or use the Browse button to select the folder you want to synchronise/backup.


In my example (above) you'll see I've selected C:\Docs. For you this could be any folder.

NOTE: By default when selecting a folder, all files and folders below that folder will be synchronised. 


Create the first folder on the destination drive (USB drive):


You only need the first folder but it's good to do this otherwise all the files from below C:\docs would go into the root (beginning) of the USB drive.

On the right hand side enter your destination folder - in my example J:\Docs:


Click Compare - in my example (above) it compared the files in C:\Docs with J:\Docs. Because this is the first time I am synchronising these folders, the right hand pane J:\Docs is empty (there are no files on the USB drive yet).


Click Synchronise


Click Start

When it has finished it will play a tune and say Completed - click OK.

The next time you want to synchronise the folders:

1. Insert the USB drive
2. Browse to the USB drive \FreeFileSync
3. Double click FreeFileSync.exe
4. Enter the source into the left (C:\Docs in my example)
5. Enter the destination into the right (J:\Docs in my example)
6. Click Compare
7. Click Synchronise

Save the configuration
Once you have the source and destination folders on the screen, click Program | Save configuration

Save the SyncSettings.fss_gui file to your FreeFileSync folder on your USB drive (J:\FreeFileSync in my example).

The next time you start FreeFileSync you can click Program | Load configuration and select the SyncSettings.fss_gui file.


Sychronisation - an example
I've created a new file in my C:\Docs folder called new.txt. I've started FreeFileSync, clicked Program | Load configuration and selected the SyncSettings.fss_gui.

I clicked Compare and this is what I see:


You can see that FreeFileSync is detected the new file (new.txt).

Click Synchronise 


It will copy the new file to the USB drive.


What next?
When you need to synchronise your files (back them up perhaps!) then do the following:

1. Insert the USB drive
2. Browse to the USB drive \FreeFileSync
3. Double click FreeFileSync.exe
4. Click Program | Load configuration and select SyncSettings.fss_gui
5. Click Compare
6. Click Synchronise
