Many Windows users report having encountered difficulties since installing a recent update to their operating system. Generally speaking, it can be advisable to wait a few days before updating Windows, to avoid encountering problems still unresolved by Microsoft. The same applies to Apple's macOS.
The latest optional Windows update (KB5043145) seems to be causing a few problems. According to numerous online reports, it sometimes gives rise to a blue screen, synonymous with a crash, and sometimes to connection problems with WiFi or Bluetooth. USB ports out of order and various other bugs have also been reported.
