Q. Original Title: Wireless Logitech keyboard and mouse lags intermittently suddenly

Have had Logitech M185 mouse and K270 keyboard for years and got an HP preinstalled Windows 10 PC this past Christmas w/o any issues until yesterday.

I noticed huge lag in keyboard responsiveness and then slight lag with mouse. Ended up replacing with fresh batteries to no avail.

Then switched USB from hub to PC itself and 2 USB ports, resinstalled drivers (even though it said everything working well). Noticed that some of the things I did made it work temporarily and then sometimes mouse worked but keyboard not at all.

Tried to restore Windows 10 OS to last month when everything worked well but took forever and I had to leave but my wife says screen says it failed.

Using corded mouse/keyboard without any issues (had to use to restore/log in during multiple restarts, etc).

Any thoughts or suggestions? I have not installed anything lately although Windows updates itself along with a few other programs. Working well for almost 5 months.
