I am newly told I don't have permission to do simple things
Windows 7 Home Premium, 64 bit. I am the administrator (although an admin. password was never set up). For no obvious reason I am now often told I don't have permission for simple operations such as moving a file from one folder to another. Then I get a momentray black screen then "Do you want this program to alter your computer". After that sometimes I can carry out the operation, sometimes I am told I don't have permission and must abort the operation. This happens with other operations which I can't remember at the moment.
Word is a particular nuisance. If I open and amend a Word file and try to save it under the same name by pressing CTRL + S and it saves immediatley. Abnormally, instead of the save being carried out, I am offered a Save D. Box with the file name in it. If I then choose Save I get the error as in the attachment to this post. I must assign another name which I do. The save is then successful. But then I can't delete the old file ("You do not have permission"). This happens every time. My machine is getting littered with un-deletable Word files. (No problem with Notepad nor, I think, with other programs).
I have User Account Control Settings set at default ("Always norify..."). (In any case, that just involves changes being made to Windows.)
How can I get back to normal please?
Thanks.
EDIT: In one folder, (not others) when trying to delete a Word file, I get a D. Box that mentions networks. I am not on a network! (Please see second attachment.)
