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.

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!
Windows' command line tool only remembers 300 lines by default - this can be a nuisance especially if you are working with long list outputs. However you can easily increase the number of lines that are shown.
Open a cmd window, right-click the title-bar and select Properties. Go to the Layout tab and under Screen Buffer Size set the Height attribute to the desired value of lines:
To retrieve the MAC-address of a networking device on a Windows machine you can enter one of two commands into the command line tool. To open a command line search for cmd in the main menu. After wards enter either
The line called Physical Address indicates your MAC address.
Every service you install is usually run on system startup. Sometimes these services do so without asking you before and sometimes they might even be malicious or just too heavy in resources. To select specific services that shall not be started by boot, open msconfig by calling a Run prompt through the main menu and entering msconfig.
Switch to the Services tab and uncheck any services you don't want to start anymore, afterwards click Apply and restart your machine.
On a normal Windows boot the operating system loads all the programs and services that are configured to run on system startup. If your machine is haunted by a worm though it might be helpful to boot it with only the basic Windows services running - that is called a Diagnostic boot.
To get going, open a Run prompt by searching for run in the main menu. Enter msconfig. The following window should pop up:
Selective startup should be the one that's ticked. Check Diagnostic startup instead and confirm by clicking OK. To undo the changes, just repeat the steps and check the item that was selected in the beginning.
It can be annoying if your audio player has an over-all quieter sound than Windows and other applications, so their sound always overtune whenever you're listening to music. To raise the volume of Winamp alone without meddling with any Windows settings you can use the built-in equalizer which has a pre-amp setting.
To get there go to View > Equalizer:
Turn the slider on the far left side up to the top and click On.
