this is error : i sk now - how i delete the old system files from my drive (D??
Thank you very much for all
sorry for my language

Without reformatting and reinstalling everything....there is no safe way to truely remove all the old files. This is typical as a newer operating system overrides the older one and changes the MBR of the old to work with the new.

If there is a problem with any particular file then post about repairing or removal of that file...other than that I would leave things as they are ....you could be making it very bad on trying to remove the old system files.
