Yes this version of Windows is licensed and linked to my account with Microsoft. I'm glad this is the final version of Windows as I don't like it but forced to use it as some of my games require windows 10 to play properly.


I own this custom built computer, I'm the Admin for it

And for the past THREE MONTHS... every time I right click on the CMD shortcut on my taskbar, hit admin version, click on the YES to the pop up and when it comes up I put in


As you can see from the screenshot I posted, I get access is denied. I don't know what's causing it. But I'm giving you five days to figure this out or I'm gonna dump this version of Windows for Linux and get rid of the games that force me to use Windows 10 or as I call it; Windows Charlie Foxtrot.

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 won't complete

Hi,

As per the information, I suggest that you run SFC in Safe Mode with admin privileges and check if the same issue occurs.

If the issue persist, you can check for the following:

1. Scan the Hard Drive for Errors

The first thing to do is to tell Windows you want to perform a file system check on the hard drive to ensure there are no errors. If there are errors on the drive, 'sfc /scannow' may fail.

To scan the drive for errors, do the following:

• Open an administrative command prompt. In Windows XP, click Start -> Run, and type in "cmd.exe" and press Enter. Click Start and type in "cmd" (no quotes). Wait for Command Prompt or CMD.EXE to appear in the list of options and right click it, then select
  "Run as Administrator".
• A black command prompt window will appear on the screen. Highlight the following text with your mouse: "chkdsk /x /f /r" (do not include the quotes), then right click over the highlighted text and select Copy. Next, go to the command prompt and right click
  in the middle of the window and select Paste from the dialogue menu. The command you copied should have output to the command prompt. If it did not, repeat this step until it does. After the command is output, press Enter on your keyboard to execute it. When
  prompted, press "Y" to have chkdsk scan your hard drive for errors on the next reboot.

2. Enable the Hidden Administrator Account

Next we'll enable the hidden administrator account so that you can perform the 'sfc /scannow' command in a clean environment.

To do so:

• Highlight the following text with your mouse: "net user administrator /active:yes" (do not include the quotes), then right click over the highlighted text and select Copy. Next, go to the command prompt and right click in the middle of the window and select
  Paste from the dialogue menu. The command you copied should have output to the command prompt. If it did not, repeat this step until it does. After the command is output, press Enter on your keyboard to execute it.
• Please note that you will most likely want to disable the administrator account after you have finished making changes listed in this document, otherwise anyone will be able to login to your computer as the administrator user without using a password and
  make changes to the system without any authorization. You can disable the administrator account using the exact steps you just took above, except you would replace "net user administrator /active:yes" with "net user administrator /active:no".

Hope this helps

Regards

 

Chkdsk and sfc /scannow

Black screens are frequently caused by problems related to GPU drivers.
The sfc /scannow checks the operating system protected files and compares them to the files in the component store.
If problems are found they can be replaced by files in the component store.
To fix problems in the component store you can run the dism commands, scanhealth, restorehealth.
Sometimes there is corruption that cannot be fixed by either scannow or restorehealth and this can often be fixed by an in place upgrade repair.
The chkdsk checks the drive file system.
There are different switches that can be used and some of the switches vary in the depth of the cleaning.
For example chkdsk /I or chkdsk /c are less vigorous compared to chkdsk /f or chkdsk /r

scannow------------------> operating system protected files
restorehealth-----------> image or component store
chkdsk--------------------> drive file system
