The last few Cumulative Updates, be it security or optional, appear to be bringing down the performance of Windows 10 computers. None of the updates are available to all the general Windows 10 users and neither have most users downloaded and installed them. Hence it is a bit difficult to exactly ascertain which of the updates or all of them, are contributing to the slower performance. Nonetheless, there are few methods that users, who have downloaded the updates and experienced a general slowdown, can try and restore the earlier performance.
The last three Windows 10 Cumulative Updates, notably the KB4535996, KB4540673, and possibly KB4551762 are being blamed for slowing down the performance of Windows 10 machines. We had previously reported about multiple problems caused by the optional Cumulative Update KB4535996, which was primarily intended to fix the Windows 10 Search platform. Although many users have reported the searches are being populated with relevant and needed information, the update has reportedly caused quite a few new problems, including system instability, slower boot-up time, erratic FPS, audio stutters, etc.

Over the last few weeks, starting January 2020, Windows 10 has received optional, non-security Cumulative Updates KB4535996, KB4540673, and KB4551762.

If both the abovementioned updates are not installed on the Windows 10 PC, all those fixes are included in KB4551762. Simply put, the KB4551762 is essentially a collection of all the bug fixes and performance improvement features that were sent out separately through KB4535996 and later in KB4540673. Hence it is a bit difficult to pinpoint exactly which Cumulative Update gives rise to the issues. The most prominent issue being reported by users, is a slower boot, while a few others have claimed one of the updates even brings down the overall performance of Windows 10 machines.
Experts indicate the culprit is most likely a buggy driver or faulty software that is hindering the boot process. It is quite likely that Windows 10 machines, after getting the buggy update, may have to go through a number of additional processes to mitigate the issues and boot successfully.
