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!
When you enter a home network with a device for the first time you will be asked what data you want to share with that network. If your thoughts on that matter have changed since then and you want to add or remove data to the list of shared types open the Control Panel.

Now you can check or uncheck the components you want to change. Afterwards, click on the Save changes button.
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.
When there are new updates available for your installation of Windows 7 or 8, it prompts you with a Window asking you to either restart the computer or to postpone the installation for 10 minutes, one hour or four hours. Either option may not be the best sometimes, so why not postpone it by a full day in the first place? To achieve that, open the Local Group Policy Editor by searching for group policy in Windows' main menu.
In the left pane, navigate to Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Windows Update. Click it once and select Re-prompt for restart with scheduled installations. Double-click it and check the Enabled checkbox. Now a counterbox becomes available on which you can specify a number of minutes, enter 1440 for a whole day, then apply the changes.
