SP-2 worked for my computers on the day it was released.
My computer was already clean of malware as well as other routine
maintenance accomplished.
The expected result of a successful installation was achieved.
Exactly what bugs are you referring?
SP-2 available a few months ago is identical to SP-2 today and SP-2 in
a year.
Instead of waiting, research your specific hardware and software for
possible issues and resolve them in advance.
If all you are doing is waiting, you are wasting your time.
