Windows 10: Is there any LOCK button?

1. Is there any LOCK button for parents to lock PC that is being used by kids?2. Scenario 1. After the time is up, the children ask for more time. Then I gave an extra hour. The children use the PC for half an hour before they take a break. After taking a break, they want to continue using the remaining 30 minutes but it says the time is up. Why are the remaining 30 minutes still running even though they have signed out?3. Scenario 2. When the pc is locked, the child asks for extra time, I give one hour. But the child does not want to login yet. After a few hours, when the child wants to log

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??

 

unable to scroll lock screen after update htc mozart

If you can not slide the lock screen it may well be an issue with the digitizer.

The only other suggestion I have is perform a hard reset to return the device back to factory defaults. If that does not work, you will have to send it in for repair/replacement sushi21.

Steps to hard reset using phone buttons:

• With the phone turned off, press and hold the VOLUME UP and DOWN buttons, and then briefly press the POWER button.
• Wait for the screen to show the instructions on how to do the factory reset, and then release the VOLUME UP and DOWN buttons.
• Follow the instructions onscreen to factory reset your phone.
