 ## Install Minio service
 
-Download and install the [Windows Server 2003 Resource Kit Tools](https://www.microsoft.com/en-us/download/details.aspx?id=17657). It 
-is old, but still works on recent Windows versions. On the latest Windows versions you'll get a warning message, but you can run
-it anyhow by clicking on "Run the program without getting help".
+NSSM is an opensource alternative to srvany. NSSM is still being updated, and works on Windows 10 as well.
 
-Start cmd.exe and install the Minio service:
+Download [NSSM](http://nssm.cc/download) and extract the 64 bit nssm.exe to a known path.
 
 ```
-sc create Minio binPath="C:\Program Files (x86)\Windows Resource Kits\Tools\srvany.exe" DisplayName="Minio Cloudstorage"
+c:\nssm.exe install Minio c:\bin\minio.exe server c:\data
 ```
 
-Now we need to configure srvany using regedit. Start regedit and go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Minio and
-create a new key called Parameters.

+When you start services, look for the Minio service and start and stop (or make it automatically start at reboots) the service.
 
-Within the new key create a new String value called Application and enter the path of your Minio binary. (eg. C:\Minio\bin\minio.exe) And create
-another String value called AppParameters with value `server c:\data` where c:\data will be the location of the data folder.

+### Configure user
 
 It is a good (and secure) practice to create a new user, assign rights to the data folder to this user and change the service Log On info to use the newly created user.
