Winreducer installed software in my running O.S after winreducing
Windows 10 V2004H2 with Winreducer v2.4.0.0

I found  a registery item :
After looking closer  I found an new Hive  HKEY_LOCAL_MACHINE\BCD00000000  in my registery that i named :
WR_EX_100_Boot_Software.hiv 20,480 10/22/2020 08:13 -a--

Yesterday I installed  my VPN again and took a backup :                            Boot2-OK02.TBI 3,759,009,792 10/21/2020 03:48 -a--
This morning  After discovering those registeries i took a new backup : Boot2-OK02-WR.TBI 4,089,458,688 10/22/2020 14:59 -a--
So there is a difference of 330448896 bytes between the 2 backups
Bacups are compressed, so there are  more bytes added
most program are installed onto drive D, temp ,IE Temp is onto D:

So What is happening or what is going wrong ??
