Windows automatic repair after use tweaking program

[Laurent]

Hello
In first, sorry for my bad english, i'm french

I used tweaking program on a computer who had some issues with windows 10, and after reboot, i have the "preparing automatic repair" and "diagnosing your pc"

I tried a system restore but it didn't work
i tried also a sfc and a chkdsk, but it didn't work also

I don't know what i can try more to solve this problem
Can you help me?
Thank you a lot

As you've said you have tried restore points, sfc /scannow and a chkdsk, I'm not sure what the status of your machine now is - is it working or not ?

Can you get into the advanced boot options to try Startup Repair to see what it reports ?

That can produce similar notifications to what you've had and will report what it is able/unable to do.

If that reports it is unable to repair, reboot to normal mode and open a Command Prompt (Admin) and enter these cmds which can take a while to complete.

dism /online /cleanup-image /startcomponentcleanup

dism /online /cleanup-image /restorehealth

sfc /scannow

shutdown /r /t 00

and see what you get after the reboot.

BTW - Your English is fine.

Thank you for your fast answer 
For his status, it isn't working at the moment
I forgot to say it in my first post, but i tried a startup repair also, but it didn't work also, i have the message "startup repair couldn't repair your PC"
I will try tommorow those cmds.
I really hope it will work

In case, is there other cmds to do ifyour cmds here won't work?
Thank you

The machine would need to boot up to access a Command Prompt (Admin) to execute those cmds.

Does the machine do that ?

If it does and you can open Windows Explorer/This PC then the next step would be for a repair install which doesn't affect personal stuff or installed programs.

You will need Win 10 install media to perform that which you can create after reading the instructions at https://www.microsoft.com/en-gb/software-download/windows10

When you insert the install media, double click on its drive which when using a DVD will start the process but will open to its files when using an USB where you would then double click on setup.exe Application to start the process.

Yes, the PC can acces to command prompt with adavanced option
In case i have a bootable usb key of windows 10
i will try this afternoon all what you say
Thank you

I once did a trial repair install of my 1903 version of Win 10 and it took about 7½hrs compared to about 4hrs with earlier versions of Win 10.

Unlike previous versions of Windows, Win 10 doesn't ask for a product key during a repair install as it's digitally activated.

Hopefully those cmds will do the job without the need for the repair install.

I hope so also
