Defraggler is a rogue hijacker of Windows' built-in HDD defragmenter.
Because of Defraggler, my SECOND computer CAN'T complete a defragmentation process on 100% (fully / to the finish). Windows' built-in HDD defragmenter is used.
2) Re: hijak computer. . . what? there is no way for Defraggler to do this, it's not like systernals Process explorer where it can replace the built in
3) sounds like you made something happen. can you Without bold or caps describe to us what steps you took and maybe, more in depth what you mean hijacked the computer? Start with what Version Windows you are using and what version of Defraggler
