The Getty Conservation Institute, of Los Angeles, and Egypt's Ministry of Antiquities completed the project, the facets of which included shoring up the tomb's wall paintings and adding a new ventilation system to protect against future damage. The tomb has been visited by a great many people through the years, and those visitors have stirred up dust and, merely by breathing, added large amounts of carbon dioxide to the area.

One particular point of concern for the conservators was a number of brown spots thought to be growing in the paintings on the walls. Scientific investigation confirmed that the spots were microbes but that the microbes were dead and had not spread in the past century. The one thing that the microbes had done was grow into the wall paintings themselves, so removing the microbes without damaging the painting wasn't possible.

The tomb of King Tut, who reigned about 1353–1336 B.C., was not exactly off-limits during the restoration:

• Egyptian officials in 2015 conducted extensive searches of the tomb and announced that they thought that the tomb contained a hidden chamber.
• A National Geographic Society follow-up survey in 2016 found no such evidence.
• A team Italian archaeologists had another go in 2017.
• In 2018, the Egyptian Ministry of Antiquities did their own intense radar scans of the tomb and said definitely that no hidden chambers existed inside the tomb.
