Last week, Microsoft released update KB4532695 to address a number of issues in Windows 10 of the 1909 edition, also known as 'November 2019 Udate'. The update fixed the problems but unfortunately showed more that didn't exist.
Η updated version KB4532695 fixes some bugs in File Explore, but also some bugs that make the frame searchs in Explorer toolbar useless.
Unfortunately, the search remains different from the way we knew it from previous versions of Windows 10.
Ωστόσο, το τροποποιημένο πλαίσιο αναζήτησης δεν είναι το μόνο πρόβλημα που έφερε η KB4532695. Πολλοί χρήστες αναφέρουν ότι μετά την εγκατάσταση της ενημερωμένης έκδοσης, τους παρουσιάζεται BSOD, και έχουν προβλήματα με τον ήχο και τις Bluetooth connections.
There are also some posts that report problems with BitLocker and network connections. The latter issue does not appear to be due to a specific driver or network adapter and affects both wireless and wired connections.
After installing the update, the connection bandwidth drops to 1Mb / s and none of the built-in troubleshooting tools can solve the problem.
Removing the update alone will help you get your system back to normal.
