Some weeks ago I installed the VPN that comes with Mcafee. Only change for a long time. But I got no notifications from that, or Mcfee for that matter. So just a Microsoft glitch I suppose.

Some years ago the super computer that does the calculations for weather forecasts was hacked. This was made me think of the present attacks as a cause for my glitch.

Microsoft has a glitch,
Cough ,cough ,
Microsoft is a glitch.

Ian made a good point with his quote. I work in a large hospital. There's numerous building management and biomedical systems and when something goes wrong, I always try a reboot first and that often fixes whatever the gremlin was. It's not that we have that many issues over the course of a year, but the numbers quoted are about right when it comes to decide whether a serviceman is needed or not.

On a related note, these systems run several operating systems. They all have their upsides and downsides though all, including Windows Server, are secure and reliable. To mention a few, the PABX & paging system run Linux and the nurse call system & the voicemail server run Windows Server.

My Brother all in one printer which is about 8 years old and has worked faultlessly till now suddenly refused to print from either my laptop or our desktop, both using W10.
After doing all the usual things, restart, delete and reinstall drivers etc, etc tried getting on to Brother support.
Turns out that a W10 security update in May clobbers it.
Remove the update and voila! all fixed.
Damn Microsoft do gooders!!!
