While the Windows 10 April 2018 update was part of a massive beta test using the Windows 10 Insider programme, it seems some serious issues still slipped through.
The latest one to come to our attention is pretty serious and involves Explorer.exe crashing every 3-5 seconds, rendering a user’s machine more or less unusable.
The issue appears related to the new TimeLine feature and occurs when the TimeLine synchronizes user activity to the cloud.
According to users on Reddit two temporary solutions exist:
Go to Settings > Privacy > Activity History > uncheck the option “Let Windows sync my activities from this PC to the cloud“. Once you’ve done this, simply switch to another Settings page, and then return to the previous one. Go to “Clear Activity History” and hit the “Clear” button. Explorer.exe should stop crashing now.
The second is slightly riskier and should be used by users who know what they are doing:
Using Regedit, navigate to hklm\software\policies\microsoft\windows\system and toggle the “enableactivityfeed” key from 1 to 0. This disables the TimeLine feature
So far Microsoft has not responded to the issue, but a Feedback Hub item exists for the problem, which can be viewed here.
