You may have to do the delete while in Safe Mode of Windows. The following is the advised method of clearing the W U download folder, and you'll notice at top a "stop" of the automatic update service, and at the end a re-start of it.
From main Start menu, select RUN, type in
CMD <Enter-key>
type in
net stop wuauserv <Enter-key>
Go to Windows Explorer.
Look on your system drive (usually C ) and look at the Windows folder name. Like Windows or WINNT.
Modify following as appropriate.
If your Windows folder is C:\Windows. Look at this folder
C:\Windows\SoftwareDistribution\Download
If you find files in there, delete them. That folder is where files are stored from W U downloads.
Go back to Command prompt window.
type in
net start wuauserv <Enter-key>
EXIT <Enter-key>
