Troubleshooting the 0xC002001B Error Code in Windows 10
As Windows users, we’ve all encountered our fair share of frustrating error codes. One of the more common ones is the cryptic 0xC002001B code that prevents us from updating or installing apps from the Microsoft Store.
This issue arises for a variety of reasons but can ultimately be resolved with some diligent troubleshooting. In this guide, we’ll walk through the top methods for banishing error 0xC002001B to the recycle bin once and for all.
What Triggers the 0xC002001B Error?
Before diving into solutions, let’s briefly cover what causes 0xC002001B to rear its ugly head. Potential culprits include:
- Outdated Microsoft Store apps that need updating
- Corrupted files or incorrect permissions in the Store’s cache folders
- Issues with the Microsoft Store Install Service
- Incorrect date and time settings in Windows
The error most commonly occurs when attempting to update or open UWP apps from the Microsoft Store itself. Sometimes a particular app triggers it, while other times it pops up more randomly.
Installing the KB5015020 Update
The first thing to try is installing Microsoft’s KB5015020 update . Microsoft specifically released this cumulative update in May 2022 to address authentication errors that were blocking access to the Store.
To install it, head to Settings > Update & Security > Windows Update and click Check for Updates. If available, download and install KB5015020. A reboot may be required.
Running the Store Apps Troubleshooter
Another handy built-in Windows tool is the Store Apps troubleshooter. It can automatically scan for and correct common Microsoft Store issues.
To run it, go to Settings > Update & Security > Troubleshoot > Additional Troubleshooters. Locate and launch the "Windows Store Apps" troubleshooter. Follow the prompts to complete the automated repair process.
Resetting the Store Cache
Sometimes clearing out the Store’s cached data can resolve error 0xC002001B. Here are the steps:
- Open the Run command (Windows + R)
- Type "wsreset.exe" and hit Enter
- Let the command finish (it may take several minutes)
- Restart your PC
This will reset and recompile the cache used by the Microsoft Store. Upon rebooting, try updating or installing an app again.
Checking Date and Time Settings
Along the same lines, verify that your date and time settings are correct in Windows. Inaccurate system times can interfere with authentication processes in many apps, including the Microsoft Store.
Go to Settings > Time & Language > Date & Time and make sure "Set time automatically" and "Set time zone automatically" are both enabled. If not, turn them on to sync your clock with the internet.
Enabling the Store Install Service
Another potential culprit is the Microsoft Store Install Service. Make sure it’s set to run automatically:
- Open the Run command (Windows + R)
- Type "services.msc" and press Enter
- Find "Microsoft Store Install Service"
- Open its Properties and set Startup Type to Automatic
- Click Apply and OK
- Restart your PC
This ensures the background service that enables installing apps from the Store launches correctly each time you boot up.
When to Contact Microsoft Support
Hopefully one of these troubleshooting tips resolved your 0xC002001B woes. This error can be tricky to pin down, so don’t hesitate to contact Microsoft Support if you continue experiencing issues with the Microsoft Store after trying these fixes. They can run deeper diagnostics and potentially suggest other novel solutions.
In the meantime, hang in there – with a little perseverance, you’ll have that Store running smoothly again in no time. Let us know in the comments if you discovered any other methods for banishing error 0xC002001B!
