Toshiba stated to me that I must purchase my original recovery software for Satellite S55-B5289-S/N PSPRBU-004001, and pay $39.95 plus shipping and tax • SW Media - USB-Satellite S55-B-Windows 8 64bit Std-SP . Why can't I download FREE from Toshiba Support website, I asked and Toshiba Tech said no, is that true? Also, MICROSOFT TECH SUPPORT , twice had done a downgrade from an upgrade of WINDOWS 10, and now my 2013 version has a product key identification number that is not correct, so the Toshiba tech stated if Microsoft did it correctly in the first place, they should have accessed the recovery software from the partition drive . PLEASE ADVISE AS TO WHAT I SHOULD DO, BECAUSE I EXPERIENCED PROBLEMS WITH UPGRADING TO WINDOWS 10,WHICH CAUSED WINDOWS UPATES NOT TO FUNCTION PROPERLY, SO AT LEAST WINDOWS 8.1, IS WORKING, YET SOME UPDATES FAIL TO INSTALL ON A REGULAR BASIS.
