Thanks for the answer, I have already found solution that works for me, so for the others who have similar issues:
Disable "Allow Indexing Service to index this file" file attribute for the entire drive, and then re-enable it only where desired (Documents, Pics, etc.).
Manually stop Wsearch service, delete entire All Users\Application Data\Microsoft\Search directory and reboot. All settings will be reverted to their defaults and index rebuilt.
