My banking app is nagging me to do this, so suppose I must.

I'll do my Win7 Pro laptop first.

Have Googled it, but as usual as many questions as answers.

Ideally, the update would retain all my files data and apps. Obviously
some apps may need updating too - but assume they'd tell me if this is so,
if it doesn't happen by magic?

Ebay has plenty CDs etc for sale for a modest sum that promise to do just
this.

I do have the laptop backed up - using the Win7 facility - to an external
HD. Would I be able to retrieve my files from that if anything goes wrong
to the new Win10 while installing? Or should I do a second backup of the
files I know I might want later? JPGs and so on.

As usual, an idiots guide would be appreciated.
