Just a quicknote to people who are upgrading their Toshiba tablet PCs from the Toshiba customized version of Tablet PC OS to Windows Vista build 5472. MAKE SURE THAT YOU EITHER BACKUP OR IMAGE YOUR HARDDRIVE!!!!
After upgrading, I get a BSOD immediately and haven’t gotten around to figuring out which software component is causing the problems.
Clean installs work well (if only Toshiba would update their utility programs!).
