The system on which I am typing this has upgraded itself to the latest version of Microsoft's Edge browser.
No problem there as I believe in keeping a working system up to date.
However I have had to go into settings and make some changes from the default in order to maintain privacy and what devices I want it to synchronise with etc – Basically how I want to run it.
Before someone jumps in and says why do they have to disrupt things, the new version offers a far higher degree of customisation, which in my opinion looks to be useful – but I have just had to set things up before using the new system.
IMHO the upgrade and the increased options for security is worthwhile – but you must check it does what you want first.
