There is a plenty of failed updates. I had restarted the computer before, but I got black screen with cursor, so I had to restart it again. Do I have to reinstall Windows? Is there a way to redo updates? EDIT: I have Windows 7 Professional.
i have a question to your question;which windose?? you cant expect members to provide answers if for all they know it could be w95, you know.
Reboot to safe mode, delete the "c:\windows\softwaredistribution" folder and reboot into normal mode, run WU.
I am not sure now if Windows installed right updates, after I had deleted SoftwareDistribution content in Safe Mode.
C:\windows\softwaredistribution is the folder where updates are collected and processed. There are two others folders (more in reality), one is Download where the updates are downloaded and DataStore where a database with edb files are stored. When you delete the folder SoftwareDistribution, Windows must rebuid these informations as it was the first time you launch updates. Clearly some of this files were corrupted with precedent updates, that is why it is ok now. Sometimes not.
