The reason that HWiNFO changed how the support for shared memory (The feature Rainmeter was using to get info from HWiNFO) has nothing to do with Rainmeter and everything to do with commercial groups decided to reverse engineer how it worked and abused it without supporting the project, which I feel is really unfair to Martin (Dev behind HWiNFO) as maintaining HWiNFO is not a simple task.
We looked into it and we would have to make a fork of that fork (which we do not need more code to maintain), or do a lot of work implementing a headless browser and scraping the web server in order to implement Rainmeter support in a way that does not give Rainmeter a stupid amount of permissions.
