Windows - how to open and remove them for cleaning

This is the style of double-hung window the builder has installed in our condos.

This is the window in the front bedroom of my condo.
I happen to have two identical double-hung windows side-by-side. Other condos may have only one double-hung window in the front bedroom.

This is the right side of the window showing the security lock on the left and the tilt latch on the right.
There is another identical security lock and tilt latch on the left side of the window.

The window is locked when both of the security lock handles are pointed to the left.

To unlock the security lock, use your finger tip to pull the handle towards you and swivel it around so that it is pointing to the right.

After you have opened both security locks, place your fingers beneath the lip at the bottom and pull the window straight up.
In this photo the window has been pulled all the way up and the lip can be seen pointing toward the camera from the bottom edge of the glass.

You can clean the lower window pane from inside the house by using the tilt latch.
To open the tilt latch, place your finger tip on the tab and slide it away from the stationary frame.
Do the same with the other tilt latch tab and then tilt the top of the lower window towards you.
The tilt latch is normally held closed by a spring and you have to hold both latch tabs open with your fingers while you tilt the window inward.
The window remains connected to the stationary frame at the bottom.

The tilt latch is shown after I have released the slider tab and the window has been tilted inward. The spring has pushed the latch closed.

The window is shown in the tilted position. It is still connected to the window frame at the bottom.
Do not remove the window from the bottom connectors. Clean the window while it is tilted inward as shown here.

After cleaning, tilt the window back into its normal position until both tilt latches are touching the stationary window frame.
When the latches are touching as shown, then push the window back into place and the latches will automatically snap back into place
as shown in the next photo (below).

The tilt latch is closed and securely latched when the slider tab is centered in the slot as shown.
Close the window by firmly pushing the lower window down and then swinging both security lock handles to the left.
