How to apply the program and prior confirmation 

■Prior confirmation 

  • The PC will automatically restart immediately after the program is executed, and the update will be performed after the restart. Please close all applications in use before updating. Please save any data currently in use. 
  • There is no need to disable BitLocker drive encryption and device encryption, which are standard OS encryption functions, but if you are using another drive encryption solution, please temporarily disable it or check the guidelines for your encryption solution. 
  • Be sure to connect the AC adapter and power cord to the device. 
  • Disconnect all peripherals. 
  • Please sign into Windows as “Computer Administrator” or “Administrator” user. 
  • The username must be registered with single-byte alphanumeric characters. If you are using double-byte or single-byte space as the username, please create a new account with single-byte alphanumeric username.

  • Stop resident software such as anti-virus software. 
  • Make sure that your PC is not set to go into standby, sleep, or hibernation mode while updating. 
  • Do not restart or turn off the power while updating. 
  • If the “User Account Control” or “Open File – Security Warning” dialog appears, please check the contents, and continue the operation as indicated.
