recover Edge session

Support tickets about Edge losing tabs after a Windows reboot have been climbing steadily, and the pattern is consistent: Edge opens to a blank new tab page, the previous session is gone, and the user has no idea why. The fix is usually a single settings change, but getting your tabs back right now is a different job. This guide covers both, starting with the fastest recovery methods and working through to file-level session recovery for the cases where the easy routes don't pan out.

What Causes Edge to Lose Your Session After a Reboot?

The short answer: Edge doesn't lose your session, it just doesn't restore it by default. Out of the box, Edge is configured to open a new tab page on startup, not to resume where you left off. That's a deliberate default, and it catches people out constantly, especially after a Windows Update forces a reboot overnight.

The most common culprit is simply that the startup setting is wrong. Under Settings then Start, home, and new tab page, the default option is Open a new tab rather than Open tabs from the previous session. If you've never changed this, Edge has never been trying to restore your tabs. It's doing exactly what it was told.

The second most common cause is the clear-on-close setting. Edge has an option at edge://settings/clearBrowsingDataOnClose that lets you automatically wipe data every time the browser closes. If Browsing history is ticked there, Edge deletes the session history it would need to restore your tabs. This one is particularly frustrating because it silently blocks every recovery method including Ctrl + Shift + T and the Recently closed panel.

There's also the question of how Edge closed before the reboot. If Windows shut down normally and Edge closed gracefully, no crash-restore prompt will appear on the next launch. That prompt only shows up when Edge detects it didn't close cleanly. A normal reboot looks like a normal close to Edge, so no prompt, no automatic offer to restore. And if the reboot happened mid-session with Edge still open, Windows may have force-closed it before session files were fully written to disk.

Finally, multiple Edge windows complicate things. Edge saves one primary session. If you had three windows open across different tasks, Edge typically only restores the last active window's tabs. The other windows show up in History under Recently closed as separate grouped entries, but they won't come back automatically. This trips people up a lot, especially power users who run several Edge windows at once.

Understanding which of these applies to your situation tells you which fix to try first. If you've never touched the startup setting, start with Tier 2. If you need tabs back right now, start with Tier 1.

These methods work without changing any settings and have a decent chance of getting your tabs back if the session data is still present. Try them in order.

These steps fix the underlying problem so you never have to scramble for tabs after a reboot again. They also have a decent chance of recovering the current lost session if Tier 1 didn't work.

Advanced Recover Edge Session Fixes: Session File Recovery (30+ Minutes)

This is where things get a bit more technical. Edge stores session data as binary files in your Windows user profile. If the settings-level fixes didn't get your tabs back, these files are your last realistic option before you'd need to consider specialist data recovery software. Proceed carefully, and back everything up before you touch anything.

As a side note: if you're dealing with broader data loss on your system, not just Edge session files, the same principles of working quickly before data is overwritten apply. We've covered this in depth in our Samsung 980 Pro firmware recovery guide, which walks through how storage-level data loss works and why acting fast matters. The logic transfers: the longer you wait after a reboot, the more likely session files are overwritten by new writes to disk.

For context on how browsers handle session persistence generally, HowToGeek's browser session restoration overview is a solid reference that covers Edge, Chrome, and Firefox side by side. Edge's behaviour here is actually more configurable than most people realise, which is part of why it catches people out: the defaults aren't set up for session recovery.

Preventing Recover Edge Session Problems in Future

Once you've got your tabs back, spend five minutes making sure this doesn't happen again. The most important step by far is enabling Open tabs from the previous session in Edge startup settings if you haven't already. That single change prevents 90% of the support tickets we see on this issue.

Second priority: check edge://settings/clearBrowsingDataOnClose and confirm Browsing history is off. You can still clear cache and cookies on close if you want, but Browsing history needs to stay intact for session recovery to work. These two settings together mean Edge will always have the data it needs to restore your session.

Third: learn Ctrl + Shift + T. Seriously. It's the fastest recovery tool you have and it works before you've changed a single setting. The moment Edge opens after an unexpected reboot, that shortcut is your first move.

For tabs you absolutely cannot afford to lose, save them to Favorites or Edge Collections. Collections in particular are good for this: they're synced across devices, they survive profile resets, and they're not dependent on session files at all. Think of them as a manual backup for your most important tab sets.

One last thing: close Edge properly before rebooting Windows. Click the X, wait a few seconds for Edge to finish writing its session files, then reboot. Force-closing Edge or letting Windows kill it during shutdown can leave session files in a partially written state, which is exactly the scenario where the Tier 3 file method becomes necessary. A clean close takes five seconds and saves a lot of grief.

Avoid aggressive system cleaning tools that target AppData folders. Tools that promise to "clean junk files" sometimes delete Edge session data, which is stored in AppData and can look like temporary data to an overzealous cleaner. If you use one of these tools, check its exclusion settings and add the Edge User Data folder to the protected list.

Recover Edge Session: Summary

To recover Edge session data after a reboot, start with Ctrl + Shift + T and the Recently closed panel in History. These work immediately and require no settings changes. If the session data is already gone, enable Open tabs from the previous session in Edge startup settings and check that Clear browsing data on close isn't wiping your history. For cases where settings-level fixes don't help, manual recovery using Session_XXXXX and Tabs_XXXXX files in C:\Users\YourUsername\AppData\Local\Microsoft\Edge\User Data\Default\Sessions is the last resort, though it carries risk and needs a backup first. Going forward, the combination of the correct startup setting and Ctrl + Shift + T muscle memory means you should never need to recover Edge session data the hard way again.
