Many CAD enthusiasts have created .cuix files that restore the look of AutoCAD 2008. You will find these on CAD forums (CADTutor, The Swamp, AUGI). Note: These are user-made, not official from Autodesk.

How to install a Classic .cuix file in modern AutoCAD:
You are looking for a .cuix file (Customization User Interface). The standard name usually used by the community is Classic.cuix or AutoCAD_Classic.cuix.
Option A: If you have an old installation
The best way to get this file is to copy it from an old computer running AutoCAD 2014 or older. The file is located at:
C:\Users\<Username>\AppData\Roaming\Autodesk\AutoCAD 2014\R19.1\enu\Support\acad.cuix (Rename this to classic.cuix or use it as is).
Option B: Download from the Community Since I cannot provide direct download links to external unverified files, I recommend searching the Autodesk Forums or CAD forums (like Cadtutor).
If you cannot find a safe download link, you can build the classic look manually in 2 minutes without a .cuix file: descargar autocad cl%C3%A1sico 9.1 cuix
If you genuinely need AutoCAD 9.1 (released ~1992):
Recommendation: If you need a free, classic-style DWG editor, use DraftSight Free or NanoCAD Free. If you require full AutoCAD functionality, consider an Autodesk subscription or a legitimate older version (e.g., AutoCAD 2008) from authorized resellers.

The following story explores the quest of a veteran drafter to reclaim the workspace he knows best. The Ghost in the Interface
Elias sat in his dimly lit home office, the blue light of his monitor reflecting off his thick glasses. After thirty years as a structural drafter, his hands moved with a muscle memory so precise it was almost rhythmic. But today, that rhythm was broken.
His firm had finally forced the upgrade to the latest version of AutoCAD. When he opened the software, he didn’t see the familiar gray toolbars and compact icons that had been his "digital workbench" since the 90s. Instead, he was greeted by the Ribbon—a sprawling, colorful tab system that took up too much screen real estate and hid his favorite commands behind layers of menus. Many CAD enthusiasts have created
"Where is my 'Draw' toolbar?" he muttered, clicking fruitlessly through the 'Annotate' and 'Parametric' tabs. "Where is 'Modify'?"
To the younger guys at the firm, the Ribbon was modern. To Elias, it was like someone had rearranged his physical workshop while he was sleeping, putting his hammers in the attic and his saws in the basement.
He opened a browser and began his search. He didn't want a tutorial on how to use the Ribbon; he wanted his life back. He typed the string he had seen on a CAD forum: "descargar autocad clásico 9.1 cuix".
He knew what he was looking for. A .cuix file is a Customization User Interface file. Version 9.1 was the legendary community-made script that could strip away the modern clutter and inject the DNA of the 2008-era "Classic" workspace into the sleek, modern engine of the new software.
After navigating through dusty forums and archived technical blogs, he found a link. It felt like an archeological dig. He clicked 'Download' on the file: AutoCAD_Classic_9_1.cuix.
He went back to the software and typed the command CUILOAD. His heart raced slightly—a strange reaction to a software setting, but this was his craft. He navigated to his downloads, selected the file, and clicked 'Load.' How to install a Classic
For a second, the screen flickered. The Ribbon vanished. Then, like old friends returning home, the toolbars began to snap into place. Two columns on the left: Line, Polyline, Circle. A row on the right: Erase, Copy, Mirror, Offset. The command line at the bottom shrunk to its humble, three-line height. The workspace opened up, giving him back the vast black void of the model space where he did his best work.
Elias leaned back, a small smile appearing. He typed L for line, clicked a point, and dragged his mouse. The crosshairs moved smoothly. The "Classic" 9.1 workspace was more than just a skin; it was a testament to the idea that tools should adapt to the craftsman, not the other way around.
He picked up his coffee, took a sip, and began to draw. The rhythm had returned.
