I have a desktop computer and a laptop both running Windows XP. recently i was running a program called hamachi on my desktop when it asked me if i would like to update the program. i said yes and as soon as it finished my internet stopped working.
I have tried restaring my computer many times. I tried rebooting with last known good configuration but that did nothing. I have also turned off saving system restore points apparently. It is not a problem with my router since my laptop still works.
