Let Windows start, and then open "Scratch 1.0". Then just watch Scratch through the eras (with slightly low-quality images from the Scratch Wiki) with Windows 95 music. After that, just enjoy some nostalgia.
Thanks to OrionDark7 for the Windows 95 music from his Windows 95 simulator. Thanks to MicrosoftSam for the Windows 3.1 Start-up sound from his Windows 3.1 simulator. Thanks to Microsoft for Windows XP designs. Thank you Scratch, for 10 years of imagining, programming, and sharing! I should have joined ages ago!
