windows update problems

[lastard]

hi! windows update installed last night, but got some error message just now (can't remember which one). i cannot use internet properly (browsers are not loading). everything works super slowly. problems like skype fail to load. uninstalling via control panel does not work either. how do i fix this? ideally, i would like to uninstall the whole update in one sweep. i urgently need my computer for work today!

Angela,
We need to know the KB number of the update to be able to help....
Just in case it is SP1 -
Link below with an uninstall procedure for SP1:

Note -
If you installed SP1 yourself, you can uninstall it.
However, if your computer came with SP1 already installed, it can't be uninstalled.
