each folder is linked to a programme, in the folders see “DateInstalled” and change it, if not create the key and type the date.

to hide vm in dxdiag/display:
open regedit
go to hkey local machine > system > controlset001 > control > class > "display adaptaters" > 0000
and change the names
in dxdiag/basic:
shut down your vm
go to your vm .vmx file, edit it with notepad
at the end of the file type smbios.reflecthost = "TRUE"
leave a space
don't forget to hide the vm in tskmgr, for windows 10 you have to get rid of "Virtual machines: Yes" which isn't the case in Windows 7.
