I upgraded from release preview to 26xxx 17?? and showed 8 gb update files ran wise care pro and seemed to delete them then update to 18xx then 20xx and showing 16 gb update files, ran windows delete temp files and it went down to 8 gb again. The strange thing is my size on disk was the same as the size in 22xxx ( no update files reported) then 26xxx so either they got cleaned out and the system is misreporting or the 8 gb has been there in all versions but hidden before so not reported I've no idea which but as long as everythong works OK I'm not bothered
after the 26100.2033 update I started getting consistent memory corruption errors, but no errors in event log checked RAM (32 Gb.) with quick 15 min test - everything was fine ran 5 wimlib compress and verify tests and got 5/5 errors seems to be back to normal after reboot pretty weird thing
