10 , install limits , beyond the Microsoft terse statements"
"1G Hz CPU speed, 1GB Ram, HDD(SSD) big enough 20GB is wrong!"
The truth is (64GB or 128 are better)real minimum limits. (you need space for huge W10 updates, and for your App.'s, like OFFICE)
There are 2 versions of W10 (besides Home, Pro, etc. versions, and that is 32bit, and 64bit.)
The ISO download is free to try for 30 days, so there is no reason to not try, really. (if you have spare time) (W10 is more secure after turning MS, spying.)
32 bit runs best if at all on old computer, but not relic computers, say over 10 years old.
64bit is best of all, but is very very limited on old PC's , in fact W10-64bit fails to load, on many older PCs that run XP to W7-64bit now.
The top complaint here (besides will not install) is dead chips, post install, ( Sound chip dead, Ethernet and wifi and even graphic Engine dead or 1/2 dead ! or stuck in 800x600 resolution for ever.)
When I said "engine", that means GPU logic inside the CPU or outside (onboard or in the PCI-e x16 slot)
In both cases 32/64, if your PC has dead chips (not bad) but old chips that support for it ended at XP,VISTA or W7, just be aware, nobody can make driver pop out of thin air. (dead support equals no drivers on earth)
64bit is limited by the processor present (Gen 4 up Gen3, upgrade only) and the HD graphics chip (and even BIOS versions) Fresh Installed of 64bit may need Gen 5 ECU up.
Geek-speaks: "Your processor needs to support CMPXCHG16b, PrefetchW, and LAHF/SAHF. "
W10-64 has many limits on the processor to get all full features and a secure OS. (W10 has newer minimum security levels that must be met)
64 bit will also fail on some Motherboards and due to wrong BIOS version.
There is no UEFI mandate, My 256GB SSD (M.2) runs MBR NTFX formatted drive ; 64bit PRO, as I type now. I run ASUS top motherboard in CSM (dual BIOS, legacy mode)
32bit is also has limits: (for sure 10 year old PCs and older...) Only because main chips in the PC are dead (dead means chip maker is GONE or flat refuses to support it now)
The first thing that will limit you, will be the GPU present and for sure how old it is.
The GPU makers are many , unlike 2 for CPU's , Video chips are just 4 makers now, 2018 (AMD-ATI, INTEL, Nvidia, and VIA) (chip means GPU engine regardless of locations)
GPU makers do NOT have drivers for Tens of thousands of GPU made for 20 years. Ok, it's not going to happen. Do not hold your breath like mom used to say.
So ask them first. AMD/ATI chips, Intel HD graphics , Nvidia, VIA , Just 4 engine makers, for GPU all others are dead, gone, absorbed and killed, or like ELVIS left the building so forget the, wiki has the dead pool list. Here)
Wishing for w10 drivers from dead chip maker is silly at the least (sad to watch) Intel page super good here on HD GMA limits.
Dead PC makers here, huge.
Learn that Microsoft can not ask the DEAD for any driver, that be IMPOSSIBLE.
In the case of Intel HD they make the base rules here, your OEM will not write drivers for Intel HD.
The intel HD graphics limits are here, and 32bit on GEN4 is by SKU, (means based on each OEM PC makers rules!!!)
Basically, Intel Graphics, the HD 4200 and above is supported but not below.
The newest driver page at Intel for HD Graphics engines are here.
The 4200 came with the Haswell CPU GT2 in 2010 all the older HD engines are not supported Ivy Bridge and Sandy Bridge or older, Intel can change their mind in nano second but this is true now 2018.
That means 2000 to 4000 GPU is not supported.
The W10 support page for CPU compliance and other factors , but not covering non Intel graphics engines is where.
AMD-ATI, and Nvidia has rich support on W10, if you have their GPU, do not skip going there 2nd, after OEM checks.
If on a Desktop (real ATX spec) you can upgrade to better GPU Video card, easy. (w10 supported and VAST)
The worst case are laptop, due to 2 reason and more, the laptop GPU is soldered down (99% true on cheap laptops/notebooks) But not my Elitebook.
The other big reason is custom video ram on the mobo, or shared with main memory (cheap Emachine like) and intel only provided a base driver (kit) and the OEM made many changes to that base.
FINGER POINTING 101: (OUCH)
If you look closely in the links above, Intel is dropping 32bit support, it's days are numbered. (remember 16bit, yeah same deal)
Intel is also dropping w7 support on new processors !!! W7 is doomed by MS and now by Intel, soon. (I'm sure dream come true for them and vastly better support in the future)
Sure w10-32 may load on many old PC, but is not supported, so if there is problem don't ask them. (ask your OEM sure, it is their design and theirs alone)
Do not forget that if something is dead, you can replace it.
Desktop PCI-e slots, put in a new card there that replaces that which is found dead forever running W10, (ethernet,wifi,sound,video)
On laptops there is no PCI-express slots. So in this case buy a USB Dongle that will replace that which was found dead.
Now the facts of life, and how to point fingers (best is not, until the truth is known, ok?)
Intel did not make your PC nor design it, (exceptions) your OEM did that, like HP or DELL, and yes, point fingers there. (if need be)
Microsoft did not make your PC either (it's not an Xbox), and they got the PnP driver from your OEM, so again, don't blame MS.com? it's not their design. (nor is the PnP driver theirs )
So if the OEM says no W10 support believe it, and that puts the finger pointing squarely on you. (a fact)
They told you not to upgrade, but failed to listen, ( I too do what I want and replace parts that the OS does not like, using new PCI-e cards or new USB dongle device, killing the other dead in BIOS first)
I can also turn off the onboard GPU chip in BIOS and insert my w10 rated, GPU PCI-express card and W10 is happy to load and run .
But as they say JUST DO IT. (hdd must be good and I test it first)
But trying W10 costs you nothing with a blank 8GB thumb drive in you repair kit. (we keep a box if those with w10,w7 and linux ready to boot)
Try it , then if one chip fails to work?,then you talk to THE chip maker, not the OEM they already told you NO. (in vast cases)
What chip fails, I can not predict that, nor can intel with their odd "some SKU fail" foot notes. (this means some OEMs fail and SKU is the OEM full model number part number )
Knowing this facts make solving problems more easy or avoiding too.
If chip maker ends support it is not a conspiracy, no chip makers has drivers for every chip they made for 36 years, it's not going to happen.
Now my beef with MS.com
Why in the world not publish a compliance engine,
Down load it and ("can_ I_ use_ W10. exe) and run it.
My guess their answer is " gee it's free to try, so use the free version to test". OK I lose. (so they saved a fortune at MS, by allowing 30 day trials)
Dead means (not a bad chip blown out) (if your OEM PC maker has no drivers for W10 , you can look further below)
My use of this term means ,any maker of chips (or chipsets), is no longer in business, left the business, or merged with Kraft and now makes Catchup (LoL) ?
or they ended support on old chips now, and only support chips 10 years old or newer, (cry to their board of directors? ok? I bet they called the shots, no?)
Case in point Intel ends W7 support on new processors and related chips. (Warning will Robinson !)
Nvidia click line 1, pick legacy and read.
Learn to go to your chips, makers website and read what is there, (Broadcom or Realtek)
Drivers come from 3 sources:
1: Chip makers. (Intel, ADM/ATI, Nvidia, and many more)
2: The OEM gets it from above and may modify it.
3: Microsoft.com gets it from #2, so if missing above ,so will MS, be empty.
If all 3 told you there is no driver, believe them.
Here is a list of baseline dead makers.
