After the last windows7 update Suddenly the firewall stopped working.
I did a system restore (before the update) and it worked fine again.
The problem what occurs are:
1) Firewall shutdown (error code 0x8007042x)
according to serveral forums it has something to do with the almost obligated windows 10 update
2) Lost Aero-effects
3) Some programmas don't start from task scheduler.
It seems to have something to do with the windows10 update, but I'm still on windows7 and i can't find any solution for this error.
