PowerToys Run is fantastic as an app launcher. Not quite as good as Alfred on MacOS but then nothing is. There's a bunch of similar apps for Windows (I used to use Hain) but none ever worked quite right for me, PowerToys Run does though.
FancyZones is awfully nice too for just putting a window somewhere at a reasonable size and location.
As other folks have noted SysInternals is another similar rogue Windows product by Microsoft. Process Explorer from there is indispensible, as is Autoruns.
Listary is pretty much the best I've encounter on Windows. Fuzzy search for all applications & files with dynamic ranking of results based on usage habit + possible customization with search engines.
When I'm on a laptop of someone else, Listary is the one that I miss so much.
2. I personally tried really hard to track down a source that DOESN'T ULTIMATELY LEAD TO ADRIAN ZENZ but has failed to do so. As GameOfFrowns commented earlier, he is at a position with many reasons to fabricate/exaggerate negative facts against China. If hundreds of articles from many different organizations/countries are based on one single person, it's hard for me not to regard this Adrian Zenz as a pretense. Even interviews with so-called family relatives are connected to this magical Zenz.
Many BBC reports/articles claims a resource of "some investigation" or "some research" that either leads to nowhere or to Adrian Zenz. If one claims that it's barely possible to know what's really happening in an authoritarian country, these reports are at least as untrustworthy as China's claims. It's even more amazing that Adrian Zenz has this power to do the investigation that all other organizations/governments cannot do.
3. My personal option: China started this so-called educational camp because of the peak of terrorism in Xinjiang in 2009. And it's very possible that the anti-terrorism action went beyond what it should have. Investigations, evidence etc. should be encouraged to correct any mistake that have happened and prevent them from happening in the future. That being said, if this motive also goes beyond what it should be and turns into a means against China, the accusation makes no difference from what's accused of.
