One of the very common criticisms about Windows 1.0 was the fact that it was slow. In fact, one comparison made by The New York Times was that Windows 1.0 felt like "pouring molasses in the Arctic". That was on a system with 512 KB of RAM. This particular VM has 4 MB, the lowest possible setting in Virtual PC, and here it is, still lagging out and opening programs slowly.

Here we have Notepad open with one of the sample documents. Notepad is a very basic text editor with a small text buffer (under 16k!), still included with Windows to this day.
Here we now have Notepad running in "zoomed" mode. As you can see it takes up the entire screen, including the bit usually reserved for program icons.
Here we have Windows Write, which allows for some text customization but is still only marginally better than Notepad.
