William the Conqueror lives until 1097

In 1087 King William I of England died in Rouen.
He had invaded the French Vexin to retaliate for raids on his territory and sacked and burned the town of Mantes.
When he rode out to survey the ruins he was thrown from his horse and fatally injured.

Suppose William I lives until 1097. What are his accomplishments?
 
A second Harrowing of the North?
More seriously if the Bastard lives longer then Curthose might actually get England instead of William or Henry.
