Microsoft releases KB4571744 for Windows 10 v2004 to fix many bugs

2 min read

Since the Windows 10 v2004 test period, users have found that the defragmentation function is faulty, and the system cannot correctly record the completion time of the defragmentation.

The defragmentation function itself is executed automatically on a regular basis, and this failure will cause the system to continuously repeat defragmentation and optimization, which will affect the performance and life of the hard disk.

Windows 10 Build 17738

However, it was not until the middle of last month that Microsoft issued an official announcement acknowledging the existence of the problem. At this time, it has been nearly four months since users first discovered the problem.

Today, Microsoft finally released KB4571744 cumulative update to fix this problem, but it is still testing the fix and has not released a stable update to users.
