Windows XP hangs on startup

One of several things I'm working on at the moment is migrating people from Windows XP to Windows 7. There's various ways to go about this but we are in the main provisioning new PCs and manually bringing the data over - I'd rather not use Microsoft's tool to bring settings as we often take this sort of equipment change as an opportunity for a bit of a fresh start, with bookmarks and documents being re-imported later.

Better to see if it could be fixed. Most STOP 21A errors point to issues in winlogon.exe and csrss.exe but the "status of 0xC0000135" was an important differentiator between those and thi
