Hello,IvailoMarkov
Thank you for posting in the Microsoft community.
Regarding the 131Metadata staging failed message you mentioned, it is due to the number of tasks in the task queue being full or exceeding the quota, you can try to solve this problem by modifying the value of the quota key to increase it to the maximum value:
- Click Start, type regedit, and then press ENTER.
- Locate and then click the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Schedule\Configuration - Right-click TasksInMemoryQueue, click Edit, and then click Modify.
- In the Value data box, type 1000 (Decimal).
- Right-click TasksPerHighestPrivEngine, click Edit, and then click Modify.
- In the Value data box, type 1000 (Decimal).
- Right-click TasksPerLeastPrivEngine, click Edit, and then click Modify.
- In the Value data box, type 1000 (Decimal).
- Exit Registry Editor and reboot the machine.
Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click How to back up and restore the registry in Windows - Microsoft Supportto view the article.
