=====Windows Defender=====

If the restore button in windows defender is not doing anything to a file that was on a network drive it may because it is trying to use admin privileges to restore the file to a user mapped network drive.

Try running ''"C:\Program Files\Windows Defender\mpcmdrun" -restore -listall'' in an admin cmd prompt
to list the quarantined files and ''"C:\Program Files\Windows Defender\mpcmdrun" -restore -all'' to restore them all.

If it produces the error ''QuarantineRestore failed 0x80508014'' then try using ''"C:\Program Files\Windows Defender\mpcmdrun" -restore -all -path %userprofile%\Downloads'' to restore the files to the downloads folder.

Another option is to use the registry edit in [[win:Network Drives#Admin Access to User Shares|Network Drives]] that gives applications running as admin access to user shares.
