8.3.20 slowdows -> rollback to 8.3.15

I have multiple slowdowns on 8.3.20. Is it possible to rollback to 8.3.15 ?

okay it may be possible through the old windows control panel… i will try that

I confirm 8.3.20 has slowdows concerning me, after going back to 8.3.15 everything is ok. Thanks anyway for improving the product, waiting for 8.3.25 now.

Please excuse my ignorance, but what do you mean by slow downs? As in performance issues with this particular release?
