Hello everybody,
I have an HP laptop which originally had Windows 7 and now runs with Windows 8 (not 8.1). So far, things have been going smoothly.
Yesterday, however, the computer started to get really slow and I noticed that I am not able any more to perform various functions: I cannot open the Control Panel, I cannot open CCleaner, I cannot open Windows Live Mail, I cannot open programmes as administrator. Right now, I cannot open any programmes at all actually. In all these instances, there is either only a white window with no content (for the control panel), a small black window appears (trying to open Windows Mail) or nothing happens at all (e.g. trying to open cmd as an administrator).
I called Microsoft Support and they said that the problem is due to the CCleaner which changed stuff in the Registry. I have no idea whether this is true or not.
I cannot perform right-clicks any more nor can I copy my files on an external HDD with CTRL+C and CTRL+V. It starts copying, but never finishes. Do you have any suggestions for me? Thank you in advance, I would be really glad!
