check if you are using wsus
First you need to check if the computer is updating via the wsus server.
Run Powershell as Administrator and run these commands :
$MUSM = New-Object -ComObject "Microsoft.Update.ServiceManager". $MUSM.Services.
Check the output : if you are reading Windows Server Update Service
it’s the signal that source of updates is a wsus server.
Remove wsus from computer client
Sarch for the folder
Delete the entire folder WindowsUpdate.
restart windows update service.
You can repeat the test of the first part to check if wsus has been removed from the client.

enable ssh access on qnap
Control panel -> Network & File Services -> Telnet /SSH

Find your folder
All of you shares are under /share/<sharename>
cd /shares/myshare1/mydir pwd find . -type f -print -delete
The ‘pwd’ command will print the name of the directory you will be deleting the files from. This command will delete every file in the directory and print its name in your console (-print option).
