Windows 10: KB5015807 breaks sleep in power plan

hiAfter installing KB5015807, my desktop Windows10 21H1 power plan is broken: it shuts down instead of sleeping after the specified delay which is a pain, as I then have to rely on sorting out "recovered" files... and booting up takes a lot longer than waking!Uninstalling KB5015807 reinstates the proper sleep behaviour.Until now, updates have been installed automatically, and windows update claims everything is up-to-date except for this one offending update.No changes have been made to BIOS, or system drivers.Any ideas?Thanks.

Power plan?

Upon checking, it seems that there's nothing wrong with your system. It is usual that you have to double-click your mouse before your monitor wakes up.

For the meantime, we suggest changing the power plan by following the steps below:

• Press Windows key + S.
• Type in Power Settings.
• On the pop-up window, choose Additional power settings.
• Select High performance.

After changing the power plan, we suggest that you monitor the changes made and check if that will work for you.
