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:

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.
With preferences you make concerning single files and folders it's easy to lose track of which files you have currently set as whatever you needed them to be. This is especially important for shared files and folders since you don't always want them to be shared with everyone.
Good thing there is a list with all shared files hidden on your system - to get to it search for Computer Management in the Start menu.
On the left pane of the CM window, browse for Computer Management (Local) > System Tools > Shared Folders > Shared:
You'll get a list of items here that are shared by your computer with path and description given.
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!
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.
Under Network and Internet, click on Choose homegroup and sharing options.
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:
