Hi,

I would suggest you to run online virus scan to check if the issue is with virus.

Hi Vijay,

Thanks for your suggestion, I use AVAST! Internet Security Pro(PAID) & it found 0 problems, my thinking is I have inadvertently deleted needed files from WinSxS folder which was stupid on my part as I know not to mess with system files not knowing what their purpose is, I'm sure I'm not the only one to do this but maybe the only one to admit it & not blame it on the OS, LOL. Anyway I had no other choice but to re-install from a clean drive so I took the opportunity to install W10 & I am so glad I did.

I think this is by far Microsoft's best OS to date, so many great user friendly features & navigate with ease, too many changes I like to list but I do particularly like how quick it loads, about same as any Android phone, & the Task View feature when working with multiple windows, I added a sidebar with my favourite gadgets which is Always on Top so other windows dock to it.
