There's usually a 'cap' in the BIOS as far as how much of your system memory can be assigned to the iGPU aspect.

I'd start there, and see what's set in the BIOS - not much sense looking for a solution within Windows if the issue is at a hardware/firmware level.

as Barty says, the setting is in bios, the max cap for shared memory is 2GB.

windows has set it to 32mb? how much memory does your laptop have? 4GB? 8GB? windows 10 is hungry like chrome, it wants as much RAM as it can, it may have changed your bois shared memory settings to allow it to perform better (at the expense of graphics).

from intel:


Dedicated Memory Reporting
The graphics driver now reports some amount of fictitious “dedicated” graphics memory to the operating system (128MB by default) to work around applications issues in a number of games. These games incorrectly look for some amount of “dedicated” graphics memory because they weren’t coded with the unified memory architecture for processor graphics. The amount reported can be modified or disabled if desired by changing the following registry value:
HKEY_LOCAL_MACHINE\Software\Intel\GMM
create a REG_DWORD value named “DedicatedSegmentSize”. The value is interpreted as number of MB to report (0-512MB). A value of 0 disables reporting the dummy memory segment. If the registry key/value is not found, the driver will report the default 128MB.
