The folders with a long string of strange letters are usually updates that are installed such as service packs, they can be safely deleted if the service pack has been successfully installed. Beware that if you deleted a windows update folder, and wanted to go back to a restore point if that folder is missing it may prevent your system from going back to a previous restore point. Other than that it is pretty safe to delete the folders.

Basically they are the temp folders used during a patch update and can be deleted.  Usually little space used by them though if the patch installed correctly.

thanks to all of you, you have been very helpful, indeed the service pack 1 has never been successfully installed though it has been attempted many many many times. I have deleted  the  folders now, got 10GB of space back.
