Read this:
"Accenture is a great success story by any measure. The company’s history has been more than 60 years in the making—from the earliest days as a pioneer in the new world of information technology in the 1950s to its position today as a Fortune Global 500 industry leader.

Initially called Andersen Consulting, Accenture was formally established in 1989 when a group of partners from the Consulting division of the various Arthur Andersen firms around the world formed a new organization focused on consulting and technology services related to managing large-scale systems integration and enhancing business processes.

That same year Accenture formalized Business Integration, its framework for aligning a client’s people, processes and technology in support of its overall strategy to enable all components of the client organization to work to enhance business performance. Accenture has evolved from a systems integrator to a global management consulting and technology services company, providing the full range of consulting, outsourcing and related technology services."

Comment from my side:
Accenture was called "andersenconsulting" that est. in 1989.

That was Level 6.

Now, Level 7:
Kindle - Fire
Vulpine - a fox

so firefox is created by "mozillacorporation"

Level 8 = sabeerbhatia
Level 9 = googledoodle

so i don't find any logic.

Level 10 = sudo

related to linux, a command.

Level 12 = williamhenrygatesiii

it is something that you should know where are the comments of a photo situated to find the answer.

26 ans pls

Hey, i found the logic behind Level 8.

it says "Et tu brute" which was a dialogue from Jullius Caesar or only "caesar". So its your first clue. Write it at the right. Caesar

Now, sourcecode is "a quadrilateral" so if associated with Caesar its a square which makes Caesar Square, a coded language.

So the main text is: w!oeaiffettlmnohlhhieduoleisointdkstfadmoelhtneanyeehcrietvneool

Now, the no. of letters (64) square rooted gives 8. So write it as 8x8 square.

w!oeaiff
ettlmnoh
lhhieduo
leisoint
dkstfadm
oelhtnea
nyeehcri
etvneool

Read it vertically: welldone!thekeytothislevelisthenameoftheindiancofounderofhotmail

which when grammatically corrected gives:

Well done! The key to this level is the name of the indian co. founder of hotmail.

So search for him. He is Sabeer Bhatia
That's why answer is : sabeerbhatia

then tell the answer of level 26 plzzzzzzzzz

Level 26:
Tick Tock Tick Tock means the sound of a clock. and a clock brand "clyde" is the answer.
