Something wasn't done correctly. I just ran the command on my computer and had the sfcdetails appear on my desktop.
Let's rerun the sfc /scannow and then use the command.
The sfc /scannow command scans all protected system files and replaces corrupted and incorrect versions with correct Microsoft versions.
Click on the Sart orb and then type cmd in the Search programs and files box.
In the pane above the search box Programs will appear with cmd below it, right click on cmd and choose Run as administrator.
If you are prompted for an administrator password or for a confirmation, enter the password, or click Allow.
A page similar to the one below will open.
Type in sfc /scannow and then press Enter to start the scan. Please notice the space between sfc and the /scannow.
If the scan finds no integrity problems in the first portion of the scan it should stop, to be sure that the scan has stopped wait five minutes, then type in exit and press Enter to stop the scan.
After the scan is finished open the command prompt as you did to run the scan and then copy and paste the command below. Once this is done you should have a new icon on the desktop titled sfcdetails. Be sure that you copy the entire command.
