The HTLM5 asks for so much Cache ?? I found this for Chrome, it seems to work for Edge too (just the name of the registry key to change) To put with other entries that we can have (UserFeedbackAllowed, etc ...)
- Open the Windows Registry by tapping on Windows-R, typing regedit and hitting the enter key.Browse to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Edge
- Add the Dword DiskCacheSize with a right-click on Chromium and the selection of new > Dword (32-bit value) from the context menu.
