How to fix
Windows Store Error 0x87AFo813
on Windows

I tried to install the converter of Youtube videos from Windows Store. Failed with an error code 0x87AFo813. Then I‘ve attempted to install a couple of other programs, but the download process ended up with the same error message. I performed Windows Apps Troubleshooter, and it said: „Windows Store cache may be damaged.“ Did anyone figure out how to solve this problem?

Error Code 0x87AFo813 is yet another Windows Store bug, which started emerging in Windows 10 operating system recently. Thorough investigation of the issue revealed that it hadn't been detected in older Windows versions, including earlier Windows 10 versions. The 0x87AFo813 error shows up when using Windows Store app only. When the PC‘s owner attempts to install programs, games or updates, he/she is not allowed to do so. The download process usually gets stuck, and the user receives a pop-up alert indicating the 0x87AFo813 error. No other specificities are provided on this alert, which is why it may be difficult for the inexperienced Windows user to find the culprit and the solution. We‘ve checked this problem carefully and found out that its culprit may be related to the damaged Windows Store cache. To check that, the PC user should run a Windows Apps Troubleshooter. If it shows that „Windows Store cache may be damaged“ message, then the following steps should help to fix 0x87AFo813 error.

Method 1. Reset Windows Store cache

• Press Windows key + R, type "C:\Windows\System32", and press "Enter". (C: stands for the root driver, so change the letter if needed).
• When the System32 folder is opened, scroll down and locate the "WSReset.exe" application.
• Right-click on it and select "Run as administrator".
• Press "Yes" on the UAC window and close everything.
• Restart Windows Store app and try to download the app you needed.

Method 2. Modify Windows Store Cache Folder

• Press Windows key + R, type "C:\Users\\AppData\Local\Packages\Microsoft.WindowsStore_8wekyb3d8bbwe\LocalState", and press "Enter".
• You should change the C: with the letter of your root drive and with your user account name.
• Once you access the "LocalState" folder, look for the "Cache folder".
• If you found it, rename it to "Cache.old".

• Name it "Cache" and close "File Explorer."
• Finally, reboot your PC and then run Windows Apps Troubleshooter.
