Say I have four registry values under the same key with these names:

1. ‘this\_text’
2. ‘this\_text1’
3. ‘this\_text2’
4. ‘this\_text3’

When I run the script below, two of the values will be deleted. When I  
run it again, one value will be deleted. On the third run, the last  
value will be deleted. I don’t understand why all of the values are not  
deleted on the first run.

Win32::Registry::HKEY\_LOCAL\_MACHINE.open(key,  
Win32::Registry::KEY\_ALL\_ACCESS) do |reg|

reg.each\_value do |name, type, data|

```
if name.include?('this_text')

  reg.delete_value(name)

end

```

end

end

Could someone point out what I’m doing wrong?

Thanks,  
Brad
