Let’s Get Started:
Look brother every morning when you restart your PC or laptop and open Microsoft Edge thinking that your trusted AI assistant will be ready by your side but there is nothing there! There is silence. This is the kind of problem that confuses many power users and daily multitaskers. When you look at the search bar or side panel you will find out why the Copilot AI Sidebar Disappears on Edge Browser After Restarting System problem has resurfaced.
In fact Microsoft Edge often loses its settings after updates or due to background cache corruption. Whenever the system reboots the browser’s session restore mechanism forgets to load the sidebar or blocks it. In this article we’ll take a closer look at why this bug occurs and how to root it out so it does not disrupt your workflow.
Otherwise manually checking your settings after every system restart is nothing short of torture. So let’s take a step-by-step look at the real reason behind this behind-the-scenes technical glitch.
Why is Edge Browser like this?
So the thing is Microsoft Edge runs on the Chromium engine and its sidebar management system relies on the browser’s session state. When you restart the system abruptly or normally Edge’s background processes msedge.exesometimes fail to properly save the cache of local user profiles. To understand this technical mechanism you can Microsoft Edge Official Documentation You can also visit here where you can get details about their background flags.
Simply put when the browser tries to recover the previous session on startup the side panel extension or webview container fails to load. There are a few main reasons behind this:
-
Corrupted Session Cache: When there is a conflict in the temporary files of the browser the sidebar disappears.
-
Outdated Edge Version: If your browser version is old then there are high chances of it having startup bugs.
-
Group Policy or Enterprise Settings: If the system is connected to a corporate network or office domain IT policies disable the sidebar after restart.
To fix this problem we’ll need to tweak some advanced browser flags and settings which we’ll cover in the next section. Chromium Project Portal But you can also check browser architectural behavior.
Now let’s get to the main point. If you want to Fix the Microsoft Edge sidebar that won’t Move even after a system restart Carefully follow the Steps Below.
First Open the Edge Browser and Click the three Dots (Settings and more) in the top-Right corner. Then go to Settings and Click Appearance from the left sidebar. Scroll down to the Customize Toolbar Section and see if the Show Copilot Toggle is on. If it is off enable it immediately.

Go to Settings and then System and performance tab.
-
‘Toggle Startup Boost off and then on or disable it for a few days and check if the sidebar disappears after a restart.
If the above methods don’t work edge://flagstype in the address bar and press enter. sidebaror copilotsearch in the search box. If an experimental flag is set to Disabled set it to Default or Enabled and relaunch the browser. This locks The sidebar to its default state.
After using this method your sidebar will not disappear from its place even after restarting.
Look if Microsoft Edge’s persistent sidebar disappearance is bothering you there are plenty of solid alternatives available. Sometimes a browser’s internal architecture becomes so complicated that bugs crop up frequently. In such a situation trying another browser can be a smart move.
To explore these alternative tools you Mozilla Firefox Portalof Brave Browser Official Site You can also visit where you get a different experience of privacy-first browsing.
-
Brave Browser: If you are Privacy-conscious and Want a clean experience without annoying Microsoft Bloatware Brave is an Excellent Choice. It features built-in Leo AI which remains stable without any Restart bugs right in the sidebar.
-
Google Chrome with Extensions: If you use the official Gemini extension or third-party AI extensions on Chrome the extensions remain stable even after the session is restored because Google’s extension manifest system is quite mature.
-
Opera One: Opera includes the Aria AI sidebar by default which remembers its exact position even after a system reboot. Its side panel design is very smooth and fast.
Otherwise if you have to use Edge only then the fixes mentioned in the previous section will solve your problem permanently.
Feature Comparison Table & Analysis
To understand how different browsers maintain their AI sidebars after a system restart below is a small comparison table. This will give you a clearer idea of which browser has the best stability.
| Browser Name | In-Built AI Assistant | Sidebar Stability After Reboot | Session Recovery Speed | Customization Level |
| Microsoft Edge | Copilot | Moderate (sometimes bugs occur) | Fast | High |
| Brave Browser | Voice AI | High (Stable persistence) | Very Fast | Medium |
| Opera One | Aria AI | High | Fast | High |
| Google Chrome | Gemini (Extension) | High | Moderate | Very High |
The obvious implication from this table is that if Edge’s update does not properly save session state the sidebar disappears. However in other browsers this state management works a little more reliably.

Advantages
-
Deep Windows Integration: Copilot is Deeply embedded with the System allowing You to Control Windows settings and Web Browsing in one place.
-

This means that until Microsoft completely patches this minor bug we will have to control it through manual settings or flags.
