RegEdit tweaks circa Win10 22H2:

- Set RTC to UTC (if dual-booting Linux)
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation
DWORD RealTimeIsUniversal = 1
(may act flaky if you don't disable auto-timezone and auto-sync first, although it sometimes seems 
okay to turn them back on after rebooting with this setting in place?)

- Disable Cortana
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Windows Search
DWORD AllowCortana = 0

- Disable Bing search in start menu
Computer\HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Windows\Explorer
DWORD DisableSearchBoxSuggestions = 1

I also don't use hibernate mode, so I can free a chunk of drive space getting rid of hiberfil.sys.
In an admin cmd prompt:
powercfg -h off

In Win11 22H2 the Cortana and Bing tweaks still work.

- Win11 tweak to restore right-click explorer menu
HKEY_CURRENT_USER\SOFTWARE\CLASSES\CLSID\{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}\InprocServer32
(default) = "" (edit to have empty value, which is different than not being set)
