Microsoft Edge was recently updated with “Startup
boost“, a new feature that allows the browser to launch
even faster after a system reboot on Windows 10.
For those uninitiated, the startup boost feature maximizes
Microsoft Edge’s performance on Windows 10 by launching certain
browser processes when a device is powered on. This allows the
Chromium browser to exist in a “state of readiness”.
Microsoft Edge 89, startup boost is automatically enabled
without user interaction and Microsoft claims it can improve
startup times by 29 to 41 percent.
Unfortunately, after Microsoft automatically enabled startup
boost, some users started reporting performance issues,
including a bug where closing the Edge window doesn’t quit the
browser and it will relaunch again. It will also continue to
run in the background — something you might never notice unless
you open Task Manager.
“Found multiple instances of Edge running in the background and
when I turned off Startup Boost, everything returned to normal.
I haven’t noticed any difference in performance when this
feature was enabled/disabled. Only that it took an impact on my
CPU which caused my games to lag horribly,” one user noted.
Users have also observed another frustrating problem where
Microsoft Edge will reopen immediately after exiting.
“On my laptop, with this feature enabled, after closing Edge,
it will open again, and close, and open again. Only by Option
-> Close Microsoft Edge can close it completely,” another
user confirmed the bug in a post on Microsoft

Fortunately, Microsoft is aware of the reports and the company
is now pushing a server-side update that will temporarily
disable startup boost.
“Hi everyone, I wanted to let you know we decided to
temporarily disable startup boost since it was causing a
frustrating issue for some users,” Microsoft noted in
an update to the FAQ page on March 19.
“Our team is working on fixing a couple of issues where some
customers are seeing the browser reopen immediately after
exiting and/or a message about reopening tabs when startup
boost is enabled,” Microsoft said in a statement.
Microsoft is also exploring other “potential solutions”.
However, in the meantime, disabling startup boost is the best
