Microsoft Store downloads getting stuck at 99% is a common issue, especially after Windows updates or when there are glitches in the Store's cache or background services. While frustrating, it's usually fixed with a few troubleshooting steps. Here's how to resolve it:

1. Restart the Microsoft Store Download Process

Sometimes the download is actually complete but the UI hasn't refreshed. Try pausing and recovering the download:

• Open Microsoft Store .
• Go to your Library (click the three dots ? > My Library ).
• Find the app stuck at 99%.
• Click Pause , wait a few seconds, then click Resume .

If that doesn't work, try canceling the download and restarting it.

2. Reset the Microsoft Store Cache

A corrupted cache can prevent downloads from completing.

1. Press Windows R to open the Run dialog.
2. Type wsreset.exe and press Enter .
3. A blank command prompt window will appear — wait about 10–15 seconds. The Microsoft Store will open automatically when complete.

This clears the Store cache and often resolves stuck downloads.

3. Check and Restart Background Services

The Windows Store Install Service (InstallService) must be running.

1. Press Windows R , type services.msc , and press Enter.
2. Scroll down and find Windows Store Install Service .
3. Right-click it and select Restart .
4. If its status isn't "Running," right-click and choose Start .
5. Set its Startup type to Automatic to prevent future issues.

Also, ensure the Background Tasks Infrastructure Service is running — it's required for Store operations.

4. Run the Windows Store Apps Troubleshooter

Windows includes a built-in troubleshooter for Store apps.

• Go to Settings > System > Troubleshoot > Other troubleshooters .
• Find Windows Store Apps , click Run .
• Follow the prompts and apply any recommended fixes.

This can automatically detect and fix common issues with the Store.

5. Re-register the Microsoft Store (via PowerShell)

If the Store is malfunctioning, re-registering it can help.

1. Right-click the Start button and select Windows Terminal (Admin) or PowerShell (Admin) .

2. Paste the following command and press Enter:

    Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

3. Wait for the process to complete (it may take a few minutes). Don't close the window prematurely.

This command re-registers all built-in Store apps, which can fix underlying corruption.

6. Check for Windows Updates

An outdated system can cause Store issues.

• Go to Settings > Update & Security > Windows Update .
• Click Check for updates and install any pending updates.
• Restart your PC after installing.

Sometimes a pending cumulative update resolves Store bugs.

7. Free Up Disk Space and Check Drive Health

If your drive is nearly full or has errors, downloads may hang.

• Ensure you have at least 5–10 GB of free space .
• Run a disk check:
  1. Open Command Prompt as admin.
  2. Type chkdsk C: /f and press Enter (replace C: if your system drive is different).
  3. You may need to schedule the check on the next reboot.

Also, run Disk Cleanup to remove temporary files.

8. Sign Out and Back Into Your Microsoft Account

Sometimes account sync issues interfere with downloads.

• In Settings > Accounts > Your info , sign out and back into your Microsoft account.
• Or go to Microsoft Store > Profile icon > Sign out , then sign in again.

Final Tip: Wait It Out (Sometimes)

In rare cases, the download is still processing in the background — especially on slower drives. Let it sit for 30–60 minutes . If there's no disk activity, then proceed with the fixes above.

Basically, most 99% stuck downloads are due to cache, service, or permission issues. Start with wsreset , restart services, and re-register the Store if needed. Usually, one of these steps gets things moving again.
