To enable virtualization on a machine with a Z77X-UDH3 motherboard run the BIOS by hitting Del while booting the computer.
Once inside click on the BIOS Features tab and look for the Intel Virtualization Technology entry. If it's set on Disabled, set it on Enabled. Afterwards save the changes made to your settings and quit the BIOS using the last tab from the main tab-line.
In some cases when you try to get a virtual machine running with Virtualbox or similar virtualization software you will get an error stating that 'VT-X is not available'. This relates to BIOS settings which, depending on your processor, determine whether your computer is able to virtualize stuff. These settings are not set automatically however, so it's worth a look into your BIOS whether you can actually change the setting and if your processor allows it.
The keyword to look for in the settings is 'Virtualization', it's probably placed in some advanced tab if there are some of those in your BIOS.

While SkyDrive needed complex folder mapping to be accessed from your computer's file system in the past it is now possible to download a desktop app from the Microsoft website: http://windows.microsoft.com/en-us/skydrive/download
Scroll down and click the Download the desktop app button to start downlowding. Install it afterwards by double-clicking the executable:
After the installation your SkyDrive folder will be placed in your User's folder by default:
By default Windows computers participate in file-sharing of local networks - it recognizes other devices in that network such as other computers and printers and shares all data in the folders set to do so.
If you want to turn this feature off at all or partly you can do so through the Control Panel. Open it from the Start menu and head to Control Panel > Network and Internet > Network and Sharing Center > Change advanced sharing settings.
Here you find two drop-down-menus where you can decide over public- as well as home-network specifics:
Save changes afterwards!
Windows hides certain files and folders by default to prevent the unexperienced users from messing with them. In some situations however it is necessary to view them, e.g. to backup some data from the hidden App Data folder.
So to make hidden files visible, open the Control Center and head to Appearance and Personalization > Folder Options. Open the View tab and under Advanced Settings check the Show hidden files, folders and drives checkbox. Confirm with Apply or OK and every hidden file and folder will be visible as transparent item in the explorer from now on.
When something crashes on Windows you will often see a dialog showing that Windows is checking for a solution of the problems. Frankly, Windows has never found a solution for my crashes itself and it made more sense to abort the search and go for it myself.
If you are feeling the same way you might want to turn the dialog off completely. To do that, left click the little flag icon on your task-bar once:
Select Open Action Center and head to Change Action Center settings on the left side pane, then scroll down and click Problem reporting settings where you have the option to select Never check for solutions. Confirm with OK and you should be good to go.
All of us know the situation where everything crashes around us (on the monitor) and you don't know what caused it. A nice way to track the problem on Windows is to use the event viewer - a program that lists all the events and information that are logged while the computer is powered.
To get to it, press Windows Key + R to open a Run prompt and enter eventvwr into it.
The window that opens offers you a nicely sorted overview over everything that happened - browse the left pane for the categories and click on an event in the middle pane to get information about it below:
PrtScr is the key that is used on Windows keyboard to make screenshots - this key however is specific to Windows keyboards and does not exist on Mac keyboards. So if you attach one of those to a PC you will face a problem whenever you want to make screen shots.
Now a possible solution is given with the F13-F15 keys of the Mac keyboard which are sometimes mapped as different keys on a Windows computer. It is possible that one of those acts as the PrtScr key on your machine (most likely F13) - try and press them all and then pasting a screenshot into Paint to see if Windows has mapped one of them!
After some critical problems that might appear in Windows it can happen that its own explorer crashes - the Windows explorer is the process that generates the windows and the taskbar, so if it's canceled, those will no longer be visible.
The workaround in this case is pretty simple. Call the task manager by pressing Ctrl + Alt + Del and clicking the appropriate option (on Windows XP, it starts up right ahead). On the task manager, go to the Applications tab. On the bottom of the window click on New Task...:
A Run prompt opens that you can use to start programs and processes - type in explorer here and confirm. The taskbar and all stuff belonging to it should now start up again.
Error 0x80070052 is one that appears upon copying stuff onto removable drives - at some point, no new files and folders can be created on the drive as well as be copied onto it. That problem is due to restrictions of the format the drive is using - different formats have a different number of files and folders that can be placed in the root directory of a drive (meaning the drive itself, not any sub-folders) no matter how large they are.
So to get rid of the error put all of the files on the root directory into sub-folders. If you need space to create those, delete some data temporarily. The drive should be back to normal afterwards!
