The thread I want to turn off automatic updates contains several methods for disabling the auto-update of Skype, in addition to turning off updates via Tools > Options > Advanced > Automatic updates. Below is a summary of the three that look the most promising.
Method 1 : Block the Skype update website
- Quit Skype
- Remove any copies of
SkypeSetup.exe
that has been automatically downloaded by Skype on your computer (usually in the TEMP folder) - Add the line
127.0.0.1 download.skype.com
to yourhosts
file
Method 2 : Firewall and registry
- Block the following IP addresses in the firewall:
193.95.154.39
,204.9.163.158
,204.9.163.247
,213.166.51.4
- Set the registry entry:
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Skype\Phone] "DisableVersionCheck"=dword:00000001
- Empty the TEMP directory
Method 3 : Registry updates
This is described in this answer where a registry update script is supplied.
