Hi to both of you,
Well the link you gave Mike was what I had already read on Google before I asked in the forum. The fellow is explaining about removing the Task etc. and there is no context option to "import files" into the SoftwareProtectionPlatform directory and second problem is how do you save a file in "notepad" with a "file" extension.
So, the first step was to own the file to the Registered User. It did not accept the Administrator (strange!).and did not have to delete or remove the Task from the Task Scheduler.
Next, I opened the same file and copied the xml content from Windows 8.1 and compared it to the original (faulty) file.
Finally, pasted the contents to the SvcRestartTaskLogon There was only one parameter that was wrong. Since then no more errors.
As for the mouse (or the Set along with the Keyboard) is not that old (since Feb. 2014) and the store (just round the corner) we bought it from is willing to take it back and replace it with a new one (my office also buys many things from them).
Bizarrely enough, hell's bells, no more mouse errors and that beats me. It has really nothing to do with the mouse.I am skeptic it may just be a fluke and will pop up again one of these days.
There were a few malware insurgents which MBAM removed , but these were only a few days old.
Thank you all for the help and happy trails..
