hi! windows update downloaded the latest updates and it shows as successful.But when i shut down the system it tells me not to unplug or power off the system and it says as installing updates.So i was waiting for the updates to finish installing and i waited for 12 hours but it still did not finish installing.So i had to power off the system.When is restarted the machine the next day i see a exclamation mark next to the shut down button and when i shut down it again says it is installing the updates and starts installing and it shows two dots moving from right to left.I don't know how to remove those updates so that it shuts down the normal way. help would be appreciated.mahesh
