He comenzado hoy a utilizar CCleaner y lleva 12 horas con el software actualizándolo y aun llega por la mitad. Es normal que tarde tanto?
No it is not usual for updates to take so long - so one is probably sat waiting for some user input.
And of course CCleaner cannot give it any input; so it just sits there with nothing happening.
(I’d take a guess that it’s probably Microsoft Office related).
Cancel and/or Close CCleaner.
(If it is still stuck then you may have to use Task Manager and ‘End Task’).
Restart your computer.
Open CCleaner and look to see what software it says has updates - DO NOT try to update any from CCleaner.
Open each one in turn and update it from within the software itself.
(Any Windows Updates listed should normally be left for Windows to do).
Just to add:
How may things are you updating?
When using CCleaner’s Software or Driver updaters in future (or any kind of updater) do things one at once, don’t try to do everything in one go because that can lead to problems as you have found…
