Windows 10: A new prompt

Hello All:


After other persons playback musics in my pc, the pc become very very slow!

Even I open my email account needing 2-minute.


I restarted the pc. By the end of the restart, on the stray appeared a new, I never saw,

icon. I click it, it prompted a window and said:

Run quick scan

check for protection updates

view notification options

view security dashboard


It seems that the system reminded me to Run and scan and Check ... and view ...


Where do I do these actions? What wrong with my PC?

Installation media boots to command prompt

I've just booted from known working install media to see exactly what it does when booting. The sequence of events is...

1. Windows logo on a black screen
2. circling dots appear beneath the logo
3. light blue 'Please wait' screen with circling dots
4. a command prompt window (very briefly)
5. the initial Setup page appears

Do you see steps 1-3? If so, it appears you have stopped at step 4, suggesting that something on the disc cannot be read.

Does the disc boot properly in another machine? If so, try cleaning the laptop's drive lens then try booting from the disc again.

If not, make new install media with Microsoft's Media Creation Tool, either as a bootable USB, on an ISO that you can burn to another disc. At Step 8 in Option One of this tutorial you can choose between making a USB or an ISO.

command prompt will not open in safe mode with command prompt

Would I just follow the same steps within safe mode after hooking up to the other system?
