Hi Andrea Calderón,
The error codes shown (0x80131500, followed later by 0x00000191) generally indicate that Microsoft Store is having difficulty communicating with its backend services. This is most often related to local Windows configuration, Microsoft Store app data or network and security settings.
Since the same behavior occurs when signing in with both your student and personal accounts, this further suggests the issue is device‑ or connection‑level rather than an account restriction.
I can see that Q&A Assist has already provided the initial recommended steps. Please make sure to try those first, as they address the most common causes, such as Microsoft Store cache, Windows updates, time and region settings and TLS security configuration.
If the issue persists after completing those steps, you can try the additional actions below, which focus on deeper network and system‑level factors:
1. Check proxy or network filtering
-Go to Settings > Network & Internet > Proxy
-Make sure Use a proxy server is turned off
-If you are connected to a school or secured network, try temporarily connecting to a different network (for example, a mobile hotspot) to check whether Microsoft Store opens
2. Change DNS settings
Some DNS configurations can interfere with Microsoft Store connectivity. As a temporary step to rule this out, you can try switching to a public DNS provider.
-Open Network Connections, right‑click your active network, and select Properties.
-Select Internet Protocol Version 4 (TCP/IPv4), then click Properties.
-Choose Use the following DNS server addresses, and enter one of the options below:
+Option 1 – Cloudflare DNS
- Preferred DNS server: 1.1.1.1
- Alternate DNS server: 1.0.0.1
+Option 2 – Google Public DNS
- Preferred DNS server: 8.8.8.8
- Alternate DNS server: 8.8.4.4
-Click OK, restart the device, and try opening Microsoft Store again.
*Note: This change is intended for testing purposes only. You can switch the DNS settings back to automatic afterward if needed.
3. Repair or reset the Microsoft Store app
-Go to Settings > System> System components and search for Microsoft Store
-Click on three dots icon then select Advanced options
-Try Repair first and if needed, select Reset
-Restart the device afterward
4. Verify required Windows services
-Press Windows + R, type services.msc
-Confirm the following services are running and set to Automatic:
- Background Intelligent Transfer Service
- Windows Update
- Microsoft Store Install Service
- Windows License Manager Service
As an additional check, please confirm that the device is fully up to date in Settings > Windows Update, including any optional or out‑of‑band updates, and let me know if any recent updates were installed around the time the issue started.
Once you’ve tried these steps, feel free to share the outcome and we can take it from there.
