There was a power outage on Saturday morning due to a $#%@ storm. And well the computer was on and when the power came back on i guess it had deleted the explorer.exe file. I installed to recover deleted files and unfortunatly lost all work. And now i keep on getting these messenger service pop-ups as if i had just purchased the comp and my windows update wont work and my programs access folder doesnt even work either. can someone pls help.
