'Fensterscheibe' (windowpane) is a compound noun made up of 'Fenster' (window) and 'Scheibe' (pane). The '-s-' in the middle is a linking s, which connects the two words.
Der Einbrecher hat die Fensterscheibe eingeschlagen.
The burglar smashed the windowpane.
With 'Fensterscheibe' (windowpane), verbs that describe damage or cleaning are often used. Common verbs are 'zerbrechen' (to break), 'einschlagen' (to smash), 'putzen' (to clean), or 'ersetzen' (to replace).
Kannst du mir helfen, die Fensterscheiben zu putzen?
Can you help me clean the windowpanes?
This word specifically refers only to the glass in the window, not the frame or the entire structural element. If the context is clear, in everyday language you can also just say 'die Scheibe' (the pane).
Vorsicht, die Scheibe hat einen Riss!
Careful, the pane has a crack!
window
'das Fenster' and 'die Fensterscheibe' both belong to a window in a house. The window is the whole component in the wall, including the frame, glass, and often a handle. The windowpane is only the glass part. The words can be confused because the pane is a visible part of the window. If you air out a room or open a window, you mean 'Fenster'. If the glass is broken or dirty, 'Fensterscheibe' is more precise.

Nach dem Sturm ist die Fensterscheibe im Büro gesprungen.
After the storm, the windowpane in the office cracked.
Zu Hause öffnest du das Fenster, weil es im Zimmer zu warm ist.
At home, you open the window because the room is too warm.
