With Daddy G temporarily no longer involved in the studio, Davidge and 3D steered "LP4" on their own. Enlisting the vocals of [[Sinéad O'Connor]] and Horace Andy, ''100th Window'' was mastered in August 2002 and released in February 2003.<ref name=allmusic100thwindow>{{cite web|url={{AllMusic|class=album|id=r620022|pure_url=yes}}|title=AllMusic ((( 100th Window > Overview )))|publisher=[[AllMusic]]|access-date=22 May 2009|last=Bush|first=John}}</ref> Featuring no samples or cover versions, ''100th Window'' was not as critically well received in Britain as the other records, although the album received a warmer reception internationally, scoring a 75 out of 100 on review aggregation site [[Metacritic]].<ref>{{cite web|url=https://www.metacritic.com/music/artists/massiveattack/100thwindow?q=massive%20attack|title=100th Window|publisher=Metacritic|access-date=17 September 2014}}</ref> The group collaborated with [[Mos Def]] on the track "I Against I", which appeared on the "Special Cases" single and the soundtrack for ''[[Blade II]]''. "I Against I" is also notable as the only track from the ''100th Window'' sessions that features a writing credit from Daddy G. ''100th Window'' sold over one million copies and was toured extensively (including Queen Square, Bristol—a one-off sell out concert set up in the city centre park, which was seen as a homecoming).<ref>{{cite web|url=https://www.bbc.co.uk/bristol/content/goingout/2003/08/26/massive_review.shtml|title=BBC&nbsp;– Going Out in Bristol&nbsp;– Massive Attack wow home crowd|publisher=BBC|access-date=20 May 2009}}</ref>

Also in 2003, 3D was arrested on allegations involving child pornography, which were reported widely in the media.<ref>{{cite news|url=https://www.theguardian.com/uk/2003/feb/27/arts.childprotection|title=Police question musician over child porn|newspaper=The Guardian|date=27 February 2003|access-date=22 May 2009| location=London}}</ref> 3D was soon eliminated as a suspect<ref>{{cite web|url=https://www.smh.com.au/articles/2003/03/22/1047749989803.html|title=Police clear Massive Attack star in child porn inquiry|work=The Sydney Morning Herald|date=23 March 2003|access-date=22 May 2009|last1=Barnes|first1=Anthony|last2=Marshall|first2=Nina}}</ref> (although he was charged with [[Ecstasy (drug)|ecstasy]] possession and unable to get a U.S. visa for a while) with Daddy G and fans offering their support. The arrest affected the beginning of the ''100th Window'' tour schedule.

In 2005, 3D and Davidge agreed to an offer from director [[Louis Leterrier]] to score the entire soundtrack for ''[[Unleashed (2005 film)|Danny the Dog]]'', starring [[Jet Li]]. [[Dot Allison]], who had sung with the band on the ''100th Window'' tour, sang the end title track, "Aftersun". 3D and Davidge also scored the soundtrack for the ''[[Bullet Boy]]'' film, with 3D on the end title vocals.

In 2005, Daddy G started coming into the studio, although little came of the material. He decided to instead work with a production duo, Robot Club, in another studio, feeling that he would be more free to develop tracks in the way he wanted. Meanwhile, 3D and Davidge recorded with a number of different singers as well as creating a track named "Twilight", for [[UNKLE]]'s ''[[War Stories (album)|War Stories]]'' album. Later that year, Massive Attack decided to release their contractually obliged compilation album ''[[Collected (Massive Attack album)|Collected]]'' in 2006. They released it with a second disc, made up of previously released non-album songs and unreleased sketches.<ref name=allmusic100thwindow/>
