or why not just try it first for free?
The installer does a Nero's Up and Down thumb (if your PC complies, the MS download is Free (only the License has a cost))
Near related, is why does Windows 10 cause BSOD's (the infamous Fast boot feature sure can , so turn it off)
You can read the MS page and get lost in 10 seconds or...See my W10 myths page, here.
Rule 1: Never let Microsoft tell you what to do ever. (You decide , only!) or ask your PC maker first if they support it ! See the MS bull here.
This above comment is for those that saw the free w10 upgrade message on their screen and belived Microsoft. (and your PC is now dead)
Rule 2: Microsoft W10 updates can not be blocked fully now, only delayed a tad.. Windows 10 Pro works better in this regard.
(this is new, and many folks don't like it on dial up...or using 4G or any pay as us use bandwidth, service provider)
Or just run W7 inside Linux VM forever. (with check points)
Rule 3, Do not forget to turn on the advanced processor features on first, in BIOS . NX bit and others. nor forget to edit the BCD edit file per here.
Will W10 load over XP, say year 2001 PC? Sure fresh loaded. XP is dead, (but not on any 2001 processor).
BTW some old 2006-2006 processors will load W10 but run so slow it is super pathetic.
A Pentium D , runs (last revision chip) but is overloaded 100% at the drop of a hat.
Core 2 Duo T8200 , runs but will not run like a new machine, but runs. (with great patience on the very early Core 2 CPU's)
I don't know,why would you upgrade?, see here?
Lets do Video cards first. I am a big fan of Nvidia user, and as such , here are all all card by them that support W10.
W10 for short, Windows 10 64b , 32bit PC's are LEGACY PC's (avoid these)
News flash MS says all new processors will only run on W10, (this freezes all old PC's on w7 that do not run on 10 now) ( I take this is a MS/Intel pact, WinTEL) But really is the death deal for W7 , for sure.
A very surprising turn of events.
Legacy is a huge dead weight like a battle ship anchor on MS legs. I agree, dump all legacy support. (say a 10 year swath of years and dump older) but I do offer cures here (one example only)
Won't install, or installs and DIES.(or crawls like a slug, and you smash it to bits)
W10 does not run on vast 1GHz PCs as MS told you, say made in year 2000, sorry they are so confused. see proof here. I call it the Shot Gun blast of bits!
1GHz processors started in the year 2000 with the Pentium 4, this is not supported with W10 at all.
That is 6 years of DEAD processors here.or more year 2000+
When the talking heads tell you it runs on most PC, they lie, they lie because of a 1 reason , they get a new PC every 3 years, (silver spoon in mouth and all that bs) pure arrogance or pure ignorance.(what -eva!)
Ask the guy who does this work, real techs. doing it on vast machines, and get the truth. (or a test lab that does this and reports, note that they all see the lies told by the talking heads)
GIVENS: (my comments)
64-BIT 100% Only, no comments on windows 10- 32bit (legacy PC's)
No comments on VIA processors or ARM or other oddities nor INTEL NUC. by me, ever.
No comments on SERVERS or RAID systems of any kind, or NAS .
Consumer grade PC's only.
All comments based on newest release of w10, not old ones... ever. 2017+ September time stamped now, and forward in time.
The Trap, If you Upgrade a PC, to 64bit, Windows 10 may not install, as a fresh Install, due to your having a Generation 3 Intel Processor, (eg; I7-3xxx ) the 3 means gen 3 at Intel.com
MicroSoft ("MS")has an application program to test your system for W10 64bit compatibility. (the media creation tool and downloaded Media-creation Toolx64) < at microsoft.com.
Please do know that it can fail for trivial reasons, and in fact can be corrected easy with the following solutions. (note many of these are impossible on a laptop, so avoid laptops if you can?)
I run w10 from SSD and then the HDD RAID is seperated (by my design , and intentions) So always boots, and only need 1 driver to make my fast RAID chip work. Certificates can be a horror, and a very expenive cure.
I am testing this driver now. (raid 9750-4i
INTEL FIRST: 64bit only.
They have both processors and glue logic (eg), or SOC. (system on a chip)
The hard part of SOC chips, is both the processor and GPU inside, both need to be true 64bit compliant, and most are....
The magic year is 2006, the first Intel chips that are truely 64bit, with all features needed inside.
Just because W7-64 bit runs ok does not mean W10-64b will. (due to new security rules)
The first 64bit were called Netburst 64bit.
Most those are hopeless.
The first one that works is the Pentium D extreme or 900 series or specifically 965 and up. (if at all) Presler XE was the last one and may work. Just before, July 27th, 2006 and CORE 2 came out.
That chip was like $1000 each back then, so don't expect them to be laying around everywhere.
Not only that, most old motherboards for it were FULL OF BUGs (BIOS), making that chip not fully enabled.
Intel tells that only Generation 3 chips and up are ok, and sets limits on Gen3.
You will see all GEN4 processors and newer are complaint. eg. (i7-4xxx) .
One oddity is that the early processors say like i5-650 ( that first digit is missing, that means GEN1) i3-2xxx is gen 2.
Keep in mind UPgrades are lenient and fresh installs are NOT. (and Fresh installs have more strict driver certificate signature, rule sets, and no USER bypass , option (skip this) !)
This funky certificate rule can be super complex to fix.! This is windows 10 not 7, windows 10 has higher security rules, for sure on UEFI and fresh installed.
64BIT Windows, needs these instruction features first to be compliant,
The issues are newer instructions in the processor present and working right.
NX bit , Most Early Intel CPUs with Intel 64 also lack the NX bit (NX?)
+ LAHF/SAHF , Intel introduced this in Pentium 4 G1 stepping in December 2005 BIOS may show (enable)Virtualization Technology (VT) (VT may be optional in W10.
ALL we get from Intel.com is one statement and very hard to see foot note (1) on GEN 3 chips.... read those words carefull..
The first mobile Intel chips to support XD/NX were the Core Duo,
The only sure way to know if it works right is to let the media creation tool and downloaded Mediacreation Tool x 64 , tell you it works.
or WAY 2, go here and see your processors (1000s there) and see if the features match.
The below is Intel page quotes.
only (read this foot note with due care!) Do not let this rule kill your PC dead later , say a new HDD is
needed later!!! That little "1" mark means NO on Fresh Installs.
The best way to see what processor you own is here. (A simple FREE tool, program, called coreinfo32) Intel.com also as free app for this.
The check your shot gun blast here.....
This great page shows what I call the Shot Gun blast of bits, (feature sets) See Pentium D 965 there, and all those rows of +'s BINGO, works for at least upgrade to 64bit.
Keep in mind that page does not show die revisions or stepping revisions that can effect this greatly. (means you have do learn what you really have exactly )or learn to run and trust the MS media creation tool !
Intel says use Intel Ivy bridge and newer processors, Q2 , 2012 up. Q2 is April, May , June. see the yes rule above (bad news really)
Microsoft flat refuses to list all compliant processors, they only tell you it fails at install time, making planning , near impossble.
NX bit or XD? ( A rose is a rose , by any other name? GAME)
Also note that NX (no execute bit) can be named differently so check for the option description in the BIOS, some names could be
EDB (Execute Disabled Bit),
Execute Disable Memory Protection,
EVP (Enhanced Virus Protection),
and No Execute Memory Protect.
LEARN THAT THE BIOS IN YOUR PC , MAY NEED A BIOS UPGRADE TO USE ALL THE NEW HASWELL ADVANCES INSTRUCTIONS OR W10 WILL FAIL TO RUN. PERIOD.
Virtualization Technology (VT)
The BIOS pages have a set of enables for the above, on all good motherboards ,if not? then flash it from the makers support pages.
AMD: (only) 64bit only...
If running and old PC with AMD and nforce glue logic https://en.wikipedia.org/wiki/List_of_Intel_chipsetsICHs sorry that has zero chance of working. (more dumpster fodder) send it to North Korea ? Maybe infect their uranium centrifuges?
That ended at W7 (see legacy here and read that on obsolete Nforce chips of any kind) as seen clearly here:
As you can see all things have beginning and an end, in the real world. Sorry for Captain Obvious answers. but some don't get it.
The first AMD processor that worked on W10 is (code name die F2, Socket AM2) not older.for sure E4 and older die versions NO.
The K8 series ran for many years, most this GEAR is in the dumps now. (long forgotten now or sold at GOODwill for $20)
The 64 bit W10- will not work with any processor that does not support *cmpxchg16b, prefetch and LAHF/SAHF and NX instruction sets.
That means early AMD Athlon x2 64, Opteron 185 , are SOL (sorry out of luck) , all 2005 made processors WILL NOT WORK. (and older)
Year May,23,2006 and newer at AMD are a "GO". (me sounding like a NASA Apollo 13 launch)
F2 DIE GO. called Windsor DIE (die is the chip actual inside the packaged CPU) DIES E6 , E4 and older FAIL.
All Athlons X2 64 with CMPXCHG16b instruction set are a GO. (X2 means 2 cores, nice)
The old Socket 939, 754 & earlier are A FAIL. NO GO. Buzz (Houston, sorry, orbiting is suspended)
AMD 64-bit processors, before Rev F ,will fail. Before Windsor F2 chip, dies version E6 and E4 will fail. (E = die revisions at AMD, E as in engineering change order or ECO)
These 3 - CMPXCHG16b, PrefetchW and LAHF/SAHF, and NX are required for upgrade to a 64bit version of Windows 10 from a current 64bit installation of Windows 7.
Covered here 100% (tedious to search yes) Complex page , warning ! but is Accurate.
This and below.
that ends AMD:
(PCs made late 2006, AMD processor and BIOS working right)
In all cases, the full list: (just to get w10 to load)
There are ways to try it ! (the key questions is how to regress the most easy way?)
Install W10 free, from above linked MS ISO. W10 is "free to download", no key needed now (click skip when asked), just to run it for 30 days, is always free to test W10 as it should always be... (but not W7 at MS)
Install W10, if it installs ok?, Bingo, now you know it does, now test W10 64bit on all your newly loaded applications, etc, do what you normally do.. See if you like it.?. ,most will hate EDGE, but IE11 is there.
One side effect here (bad, IMO) is the new W10 load may try to commutate your w7 to w10 license,(not using test HDD) and if that happens , you need to do the MS official 30 day rule uninstall, to get the LIC, recended to W7.
Then put back the OLD HDD last. (to get W7 back just like it was, faster and no license issues doing the CURE way)
Things to do , If we are unsure what's under the hood?
Download and run a handy utility called CPU-Z. (free) google it , it's EVERYWHERE.(this link is SAFE !)
C:\WINDOWS\System32>wmic cpu get caption
AMD64 Family 21 Model 2 Stepping 0
Look under Instruction sets and if you see SSE2, EM64T (indicates the processor has support for PAE) and either VT-d or VT-x
(which is what's needed for NX support) Turn on NX in the BIOS first. !!! and in BCDedit.
You need all that and more..
Video, (graphics chips)
Nvidia support vast chips they made on w10, 100s ! get it at there home page... http://www.nvidia.com/Download/index.aspx?lang=en-us
There are other chips that must run on W10 ,vast that never will, most never will... from 1981 to 2009?
and a endless SEA of old obsolete chips/cards.
Nforce chips are hopeless now.... Dump them , now.
From Intel's point of view. (processors only) read it and weep... facts are facts,. repeated again, do to Intel made, most PC's.
Myths true or not on Windows 10:?
THE I/O BUS: Here is huge list of chipsets on wiki.
The I/O bus chips are the most hard to discover. AKA, SOUTH BRIDGE or GLUE LOGIC.
ACH, PCH Intel chip sets . (my HP Laptop runs PCH great under w10)
Some will have dead, USB ports after W10 installations, for sure using Intel drivers direct from Intel, as they told you that.
Best of Best if HP PC is HP drivers, run those, if HP says W10 not supported why buck that (like I do)?
The BIOS in your PC must BE windows 10 certified to run new UEFI modes. (secure BIOS and boots)
My PC 2009 HP 1/2 the HP apps for it are dead under w10 BUT I DON'T CARE.
You might, and my security package HP is DOA for W10 FOR EVER.
The Intel page on this is here (called INF utility) INF are driver script installers, like ICH7.INF , etc.
In all cases load the chipset driver from HP, 1st. or things will not work right.
If not a HP PC , go to your PC makers web site click support and find your drivers. (or ask them for help)
For drivers failing see my page on same.
end , short and sweet. (now a 2009 example Laptop)
The bus chip here, Intels Ibex, you can see that it runs many important things. for sure USB bus. If its dead all things to it are dead. HP 8540w here. (w = 4 RAM banks)
W10 Tom Foolery.(as seen here)
The first line below (IMO) on processor is silly,a PC can have a processor back to year 2000. that ran that fast and are hopeless with W10, as does old PC with 2 sticks of 512mB ram back in year 2000.
It is only silly because it Invites folks (hard hours wasted) with year 2000 computer to try W10 and then find out they ALL FAIL. 2006 is the year, not 2000.
The 1GHz. is wrong (historically wrong), what matters most is what processor is on your main board. It should say and 2006 or newer there, and does not.
What MS should say or better show, all compliant listed processors, (like above , I did under Intel/AMD)
The truth is some old PC have this, but will run at 100% CPU load doing anything, A SLUG IT WILL BE.
Direct X9 is year 2002, so don't expect any PC that old to work.
The big limit is Processor. (install time limits)
The limits on desktop and mobile processors are quite different, but here is my advice on all .
Run 2GHz processor minimum, never a 1 like Microsoft says.
And best is to own a PC with all + signs seen here. the best are marked "CORE". like I3(to 9) 4xxx , generation 4 and up are always best.
The most sad case is that W10 loads, and the PC runs like crap(a SLUG), as seen on any Pentium 4 D. 965.
Avoid all Celerons ! They are just defective real chips, die., At final test if a real chip is found with 1/2 the cashe dead, bingo it's a Celeron. (same with speeds pathetic , and for dead cores)
Think about a 2 core processor, one core dead new. throw it out or sell it like that, BINGO.? (all chips are graded at final test, some can be repaired, others not, some are totally dead, or shorted pins, dead = BIN16)
All chips are bin graded at final test for many factors, even toy grade is one, (leaky pins but runs ok, in toys)
I like top bin chips. I buy only them.
version 2. 9-9-2017 (I have no best choices, only methods,. and tests... )
