Windows 1.0 PE
This is the first build to let you select what kind of mouse you're using. Most people will want to pick option 2.
The video card option screen has been updated.
The printer setup portion can actually be skipped this time!
Not much has changed about the boot screen. It only changes "Beta Release" to "Premiere Edition". I believe they used that name because this is the build that Microsoft was going to use to promote Windows.
The introduction of "ABC.TXT". Underwhelming, to say the least.
The calendar has changed considerably, as you can see.
The clock now has an icon in its "about" box.
By default, there are no window colors in this build, but you can always set some yourself!
Paint is more reliable in this build. Please excuse this terrible drawing.
Reversi seems to be the only program that has color by default.
BONUS: Here's what the "WIN1VGA" patch is supposed to look like when patched into the "Setup" program. The "Beta" build isn't officially supported, which is why it didn't show the options properly.
Unfortunately, a lot of the more unique programs, including all of the programs that involved shapes, have been removed. That's all for this one! Onto the final release builds! :)
