I had no Windows Firewall, update, defender, remote access, BITS, BFE, security center, and just about every other windows service was corrupt and not showing up as a service. After days trying countless fixes nothing worked. THen I found this program ran it once, it took about 20 min, and fixed every problem the first time. HATS OFF TO YOU and now I will definitely donate to them as everyone should since they appear to have the leg up on Microsoft and every other scam program out there.
