Windows 10: CMD not opening anymore, SFC /Scannow cannot fix any files, etc

I have had issues with my PC the past couple of days and am trying to find out how to fix them, only for it to get worse and worse.1. I tried opening the Command prompt, only for it to say the app doesn't exist anymore on my PC.2. I looked online and opened up Powershell in Admin to run an sfc scan on my PC, only for it to come back as "Cannot fix any of the errors" in both normal mode AND safe mode.3. Windows Update keeps giving me download error 0x800f0900 no matter what, meaning I cannot update anything on Windows.Is there any way for me to fix all of this, or is my HP Gaming Laptop finally

:)

 

SFC scannow not working but verify only is working

there is no problem in chkdsk I've checked When I select command prompt and sfc scannow from f8 and repair.. it shows that a reboot is required for pending repair and pending renames folder in winsxs is full of files.. what should I do??

 

sfc /scannow

Hello WGKirbyWoodwork,

My Name is Paul one of the Community Expert and a Windows User like you. I do apologize that you are having issues performing the system file checker command and its stuck at 71%. Let's try another CMD command that works similarly with SFC.

Run DISM scan

* Click Start and search and open CMD as ADMIN.

*When Command Prompt opens enter dism /online /cleanup-image /restorehealth and press Enter.

* Wait for the process to complete.

DISM scan allows you to repair your system, and if sfc /scannow stops or if it can’t fix the problem, you can use DISM to fix it.

Regards,

 

SFC /SCANNOW Errors After Update

I've just updated a Windows 8.1 Pro PC to Windows 10 using the Techbench ISO which updated without any problems. However, I've just run sfc /scannow and it found errors it could not repair. I have managed to get sfc /scannow to run without errors - see what I did below:

1. Ran sfc /scannow which showed error "Windows Resource Protection found corrupt files but was unable to fix some of them."
2. Ran Dism /Online /Cleanup-Image /ScanHealth which reported "The component store is repairable."
3. Ran Dism /Online /Cleanup-Image /RestoreHealth which failed with Error: 0x800f081f "The source files could not be found.Use the "Source" option to specify the location of the files that are required to restore the feature."
4. Mounted the W10 Techbench ISO and ran Dism /Online /Cleanup-Image /RestoreHealth /source:wim:G:\sources\install.wim:1 /limitaccess which reported successfully "The restore operation completed successfully."
5. Ran sfc /scannow wich completed successfully with report "Windows Resource Protection found corrupt files and successfully repaired them."

Please advise:

1. Why would sfc /scannow fail on a newly updated installation which ran sfc /scannow error free immediately before the upgrade?
2. Why did I have to use install.wim from the Techbench ISO at step 4 above for Dism /Online /Cleanup-Image /RestoreHealth to work and will I have to use install.wim from the Techbench ISO every time I need to run this Dism command?
3. How can I configure my PC so it has the correct install.wim file for the Dism command to work properly?
