What is dasHost.exe and what does it do?
dasHost.exe is a system process that belongs to the Delivery Optimization feature in Windows 10 and later versions. It is responsible for managing the upload and download of Windows updates, as well as other Microsoft products and services. The process helps to optimize the delivery of updates by allowing users to share updates with other computers on their local network, or even with other computers on the internet.
The dasHost.exe process runs in the background and consumes system resources, including CPU, memory, and network bandwidth. While it is a legitimate system process, some users may be concerned about its impact on system performance or its potential to cause issues with their internet connection. However, it is generally safe to leave the process running, as it is an important part of the Windows update mechanism.
Can I disable dasHost.exe and what are the consequences?
Yes, it is possible to disable dasHost.exe, but it is not recommended.
