Answer 1

Hi,

.ELT files are essentially for logging information from various places in one go. This may be related to Windows telemetry. I would suggest lowering this from full to basic to see if it helps from Settings > Privacy > Feedback and diagnostics.

I hope that helps.

Thanks for your reply.But the Settings is already set to basic  .

The last thing I did: windows update

The issue seems to be fixed after I disable all the non-windows service in msconfig

Maybe some programs do not work correctly in the new version

Answer 4

ok so much better if the problem is fixed, but did you do the scan? It could be a malicious program that was at startup.
