- Enable (or Disable) the Hidden Built-in Administrator Account in Windows Windows ships with a hidden Administrator account that's disabled by default. Turn it on with one command when you need it — and, just as important, turn it back off. The safe way. Published Jul 5
- Deleted QBDataServiceUserXX? Recreate It with QuickBooks Database Server Manager Deleting the QBDataServiceUserXX account breaks QuickBooks multi-user mode (H202). Don't recreate it by hand: let Database Server Manager rebuild the account. Published Jul 5
