I believe the following commands will fix it. After setfacl trashes the
permissions, you need to temporarily take ownership of "C:\", restore the
permissions then set the owner back. Of course this is contingent on either
having backed up the permissions beforehand, or perhaps transferring them from
a clean virtual machine.
icacls 'C:\.' /save 'C:\acl.txt'
setfacl --remove-all /cygdrive/c
takeown /f 'C:\.'
icacls 'C:\.' /grant users:f
icacls 'C:\acl.txt' /grant users:f
icacls 'C:\.' /restore 'C:\acl.txt'
icacls 'C:\.' /setowner 'NT SERVICE\TrustedInstaller'
