    Windows 10 x86 14383 Insider Pro and Core 10240

    Installation on unsupported Intel Graphics uses too much system RAM

    The Windows 10 WinPE uses 1019MB of shared system RAM to run the Microsoft Basic Display Adapter - the same driver is also found in Windows 10 after setup.

    In Windows 8.0 the basic adapter managed with 256MB - at least on my Windows to go version - for perfectly adequate performance. In XP even less video ram is used, yet it still plays streaming videos, and movies, etc.

    The problem in 10 with using so much System RAM results in slow installation past the First reboot in the FirstWndUX phase- and thus long installation times, which are prone to failure on systems with unsupported display adapters and small intrinsic amounts of RAM, e.g. 2GB, and very slow systems, when, and if, the setup completes.

    Here's the 2 situations -1- My specs show a Pentium 4 machine with 2GB system RAM and Geforce 9500GT with 512MB video RAM, which runs Windows 10, XP, Windows 8.1 Enterprise trial, etc., without any real difference in speeds - all these OSs run at perfectly acceptable speeds for everyday use. Installation remains slow while the basic video adapter is employed, during sysprep and OOBE phases.

    Situation -2- Acer Travelmate 2423 Intel® Celeron M 1.50 GHz, and Mobile Intel® 915GM/GMS, 910GML Express Chipset Family integrated graphics - This machine can run Windows 10 - it has a compatible bios, chipset and CPU, but the graphics drivers from Intel can be installed in compatibility mode for XP SR2 in Windows 7(less than 200MB), but not in 8 or 10. It runs like a one legged sloth, and has many glitches associated with low memory situations.

    Thus the basic Microsoft display.sys drivers for that chipset are used, and they allocate half of the 2GB system RAM to the graphics leaving a Measly 1GB for the system to run in. The setup may fail in the OOBE during creation of the main user account because the system crawls to a standstill after the network tries to connect, so it's best to stay offline during the install. "Just a moment..." can take hours, while the little white dots are juggled erratically above that lying (under)statement!

    So what I would like to know is, if there is a less resource hungry Basic Display driver available, and whether it can be integrated into WinPE, for less troublesome setups, and into the Windows 10 driver store so that Windows 10 can run on some less well specified, but still compatible kit in a useful way.

    I wonder if the WinPE Gurus on this forum have any input on this?

    I'm not a guru but have upgraded about 40 machines so far. All different kinds of hardware. The specs you mentioned may fall in the range of what MS says is "minimum" requirements but no machine with those specs would run Windows 10 well. That's a pretty old chipset. What's the good in having any new operating system if it doesn't run like it is supposed to.
