I have to ask all of you that question because my computer start quite slow than normal :(
When i first re-installed Windows 7 on my machine, It took only 56 secs.
But When i installed NIS 2010, it increased to 1min 45s. When the risk is deleted and NIS ask me to reboot, my compter takes about 3 and a half minutes to finish.
Some people told me to remove NIS by Norton Removal Tools and keep run it several times and restart each run and re-install NIS.
I have no idea about it, does it really work?
(sr for my bad English)
