Which type of page of replacement algorithm is windows xp and unix are using?

Windows XP uses the Local Page Replacement algorithm. It is a type of FIFO. In this, Pages are taken from processes using more than their minimum working set and Processes initialize with a default of 50 pages. XP monitors page fault rate and adjusts working set size accordingly.
