Thx for trying to help.

But no, there is actually no info at all by searching Google on the net. I've been searching all over for around 10 hours.
Bobulator does not close TCP port 135. Bobulator does exactly what I wrote I've done manually, that is just disable DCOM. Steve Gibson states himself that disabling DCOM, TaskScheduler and MSDTC will close down TCP port 135, which is what I've been trying, but when I close down all three my TCP port 135 stil remains open. Most info on the net is just 100 times copy of DCOM disabling info.

Thx tho

PS. No apps to fix system configurations. Hands on manual step by step procedure is what I need. Don't trust apps. Tho Steve's little Bobulator actually doesn't modify system or reg, unless you run the patcher.
