Key notes

Microsoft recently released a new cumulative update for Windows 10 21H1 preview; it contains several bug fixes, among them a few ones that address high CPU usage.

This new cumulative update, KB5000842, makes for the bigger update that Microsoft has launched for those who are part of their Insider program.

Notable improvements in this new build that any Windows user can benefit from are being brought to theperformanceofFile Explorerprocesses.

Namely, the developers have addressed issues where the Explorer search froze or where the program used too much memory.

Toward a more reliable File Explorer experience

Being an important component of the Windows 10 OS, File Explorer has been constantly improved via the latest Windows updates. The newest addition is a faster search bar.

However, Explorer has also been underperforming for many users, and with this update, Microsoft seems to have fixed several issues:

We fixed an issue with a heap leak that might causeexplorer.exeto consume high amounts of memory.

We fixed an issue that might cause File Explorer and other applications to stop responding for several minutes. This issue occurs after a client reconnects to the corporate network and attempts to use mapped drives to access file shares on the corporate network.

We fixed an issue that causes multiple instances ofexplorer.exeto run on a system when AppLocker is enabled and the system is not on the internet.

The update also fixes an issue where the Explorer column header gets stuck with aComputing Filtersmessage appears or the program simply freezes when you click on filters.

In case you’re still experiencing problems with File Explorer, checking for malware or removing temporary files area few useful basic stepsto troubleshoot the situation.
