Hi Jerry
Thanks for your ID/ contact details. The serial numbers you requested are
HP Laptop Serial No. CND 329 ZWX
HP 5740 Printer Serial No. (edited)
Recently I received an warning on my screen advising me of LPA. Which apparently is a confict between HP & Microsoft software. However this warning gives no explanation. I'm therefore concerned as to what action (if any) I should take?.
Best.. Fabes

HI @Fabes1,
I understand how unsettling that sudden warning must have felt—like a flashing light with no map. The LPA notice usually points to a software conflict, but it doesn’t mean immediate harm.
May I know if you have tried to open any app/site?
Regards
