Hi everyone,

I'm currently having major issues with my windows 8.1 laptop. After windows did some auto updates yesterday I can no longer open many of my programs, task manager will not open and anything 'system related' doesn't work (can't download anti virus or refresh/reformat windows), the window freezes when i try to go into specific parts of the user accounts menu (it seems to be related to actions requiring administrative privileges, and I definitely have admin status)

When i try to open one of the programs that doesnt work nothing happens for around 3 minutes then I get this: 'Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item'

Browser is working completely fine and some programs work fine including Skype.

Any help would be greatly appreciated, I'm at my wits end here!
