1.First download Windows PsTools. This tool is provided by Microsoft for maintaining processes and services through command line.
Download
2.This tool is provided in zipped format and you need to extract it somewhere.
3.Create folder called - PS on C: drive
4.We will extract all the contents of the zip file in C:\ drive into the folder PS (which we just created)
5.After that you need to start command prompt with Administrator privileges. To do this--
--Open task manager.
--Go to File
--Create New Task
---Check the "Create this task with administrator privileges" checkbox.
--Type cmd
--Press Enter
6.You will see the command prompt.
Type- c:
Type- cd /
Type- cd PS
Type- psexec -i -d -s cmd
7.Click- Agree on the license agreement dialog box
8.Then you will get another command prompt running under "nt authoriy\system"
To check if the command prompt is running under "nt authority\system"--
9.Type- whoami
You should see nt authority\system.
10.Type- sc delete WLMS
11.Type- regedit
The above command will open registry editor
12.Navigate to- HKEY_LOCAL_MACHINE-System-CurrentControlSet-Services
Locate- WLMS
13.Right click the Key and press delete.
14.Restart the computer

The simple way of doing it would be to open command prompt with administrator privileges and run the command "sc delete WLMS" and then delete the WLMS key from the registry. However, if this doesn't work, you can try the above method which will work for sure..

Now your computer won't restart every hour. Best of luck.
