Architecture (XP adds)
Blue screen of death protection
- often caused by incompatible device drivers
- XP verifies third-party drivers when you install them: warns (soft blocks) and (hard) blocks - do not install
- system restore: takes back to a safe, working, status
Improved dynamic libraries handling
- run different applications with different versions of the same DLL files
- keep different versions of the same DLL
Improved memory pool management
- optimized to handle physical memory allocation better, reducing disk-based virtual-memory use
- amount of pages of memory that the OS can map for allocation is twice Windows 2000
Improved boot and registry management
