Early in his life, Harry comes to the realisation that there is nobody either willing or able to take his side in anything, from protecting him from Dudley and his gang to curbing his relatives treatment of him. Rather than taking up the practice of keeping his head down, backing down, and running away as cannon Harry did, this Harry decides to stand up for himself, never take a step back, and always give at least as good as he is given in a fight, whether verbal or physical.
Someone insults him? He insults them right back.
Dudley and his thugs try their 'Harry Hunting' crap? Rather than apparating onto a rooftop after a run, Harry finds himself the last man standing, looking like shit and standing over a half-dozen equally badly beaten brats, with nobody quite willing to accept Dudley and co's story that the skinny Potter kid beat them ALL up.
Vernon locks him up in the cupboard under the stairs? Harry smashes his way out.
Vernon cuffs Harry across the back of the head? Harry kicks him in the shin.
Aunt Marge sics Ripper on him? He kicks the fucking mutt in the face.
By the time Harry gets his Hogwarts letter, he's already sleeping in the smallest bedroom; it was that, or the Dursleys would keep having to repair the door of the cupboard under the stairs, and the numerous upgrades of the locks and door to said cupboard were starting to garner them odd looks from repairmen. Vernon has probably had a mild stress-induced heart attack caused by his own weight problem and Harry consistently getting him angry beyond all belief.
Dudley and co avoid Harry wherever possible, but so do all the other kids. Even though Harry has never touched anyone who hasn't attacked him first, he's still branded as being little more than a smart-mouthed little thug by the uptight adults of Privet Drive (with good reason this time around), who warn their kids away from 'that Potter boy'.
As for the events at Hogwarts, both despite and because he never had anybody stand up for him, Harry mildly reluctantly finds himself standing up for everyone else who gets picked on; Hermione, Neville, Luna later on...and even though he never really goes poking his nose into things as cannon Harry did, he still finds himself stumbling or being dragged into dangerous situations despite his every intention of staying the fuck away.
Also, there are the Die Hard staples to add to the Harry Potter style; much more explosions, for instance. Almost every misadventure ends with an explosion or explosions. The bigger the misadventure, the bigger the boom. The fight with the basilisk should end with Harry and friends flying up the tunnel on Fawkes' tail as the Chamber of Secrets collapses in on itself in a fiery inferno. The rescue of Sirius ends with the tower he was imprisoned in collapsing, possibly with a 'why is there always an explosion with you!?' shriek from Hermione.
Harry should look more beaten up and bloody, too. Not that he hasn't looked bad after a scrap before, but he should look way worse, and take it much better; bloody head wounds, shredded clothing, cuts and bruises all over, but he just takes it all in stride as everyone else fusses over him.
And even though it only really happened in the dirst Die Hard movie, Harry should still frequently lose his shoes, often for odd reasons, but also quickly discover that Draco has nice comfortable shoes in his size. Hell, it's not like the little turd couldn't afford to lose a few.
Bit of a bonus to toy around with, and the inspiration behind this idea; John McClane and Harry Potter both have a nemesis played by Alan Rickman.
Obliviation Edit: also, I took a peek at the Wikipedia entry for John McClane...damn he's an awesome character...the relentless underdog hero...

As a combatant, McClane survives and thrives due to a number of factors û outside-the-box thinking, tenacity, a bizarre form of grace under pressure, and occasionally sheer luck. Paramount to his success, however, is his refusal to let a threat intimidate him into inaction. Whether bungee jumping with a firehose to escape a bomb, emptying a magazine full of blanks at an uncooperative airport security chief, blowing apart handcuffs with binary explosives, or launching a police car towards an enemy helicopter, he refuses to let his opponents control an encounter. Recently he's outdone himself - his battle with Thomas Gabriel forced him to engage martial-artists several orders of magnitude more skilled than the terrorists he fought in Nakatomi Tower and Dulles International Airport. Mai Lihn, a high-degree black belt, effortlessly disabled him in hand-to-hand combat. McClane decided against another beating and instead drove a Ford Expedition though the building and knocked her down an elevator shaft. Rand, a master traceur, however, proved resistant to even this approach. McClane instead dealt with him with the suicidal tactic of blasting him with liquid nitrogen, resulting in Rand getting shred to pieces by the revolving blades below him.
Any of his enemies seem to die a bizarre yet spectacular death. Hans Gruber, after getting shot by McClane, hangs on to Holly's wristwatch, McClane then takes off Holly's watch, thus resulting in Gruber falling 30 stories to his death. During the events at Dulles International Airport, Col. Stuart, on the verge of escaping, kicks McClane off the wing of the plane. Unknown to him, McClane pulled out a fuel plug, and a trail of kerosene is formed. McClane then simply lights up the trail using his lighter, and the plane is blown up. In 1995, he finds himself cornered as he is low on bullets and his nemesis, Simon Gruber (Hans' brother) is armed with a M60. Resourceful, McClane uses his last bullets to disconnect a power line above Simon's helicopter. The helicopter gets electrocuted, glows, and then lands in a fireball. Recently the new villain Gabriel himself had him at gunpoint û McClane then shot himself in through the shoulder to eliminate his own captor holding him from behind. Where most people would hesitate û and die û McClane simply acts, with spectacular results.
However, despite his impressive abilities, McClane could be considered a reluctant hero. Citing the state of his life, he says he gets involved in dangerous situations, "because there is nobody else to do it". This philosophy is central to his character.
