So every Dell with Home Premium installed at the factory has the same Dell Home Premium key. And every Acer with a factory installed Home Premium has the same Acer Home Premium key. Those PC's don't activate online, they activate via the BIOS SLIC table. OEM-SLP keys are useless for manual entry. They are blocked from online activation. Install with stock install media and enter that key and it will fail activation. If you install with the custom factory install media your not asked for a key. The OEM-SLP key is auto entered with a script.

The key on the COA sticker is the one you use with stock install media. I've done it a few times and had to do the phone activation. All automated and rather painless. Once that's done as far as I know next time around it will activate online without having to do another phone activation. Yes you can reinstall with that key on that hardware as many times as you want.

The motherboard swap all depends on what goes in as the replacement. If its a direct factory replacement it should have the SLIC table and no need for anything to be done if its still the factory install. If you've done a clean install at some point activation will likely fail and you'll have to phone activate it. That should go alright. The problem arises if its not a direct replacement, different model of different make and model. If you had installed with a retail key it no problem, OEM key though and you'll need to plead your case with Microsoft tech support. From what I've seen they are pretty lenient in cases where the swap was done because the first one failed.
Great info!... the only thing I know is that I've done 2 clean installs on this machine, using none HP media,

and activation was instantaneous with COA case key- no telephone activation required. I used a disc I

made from an ISO download from PCSteps... same build, same hash, same everything.

I've got some spare drives laying around, so we'll play with it using the links above regarding Win 10 clean

install- can't hurt!

Thanks again.

If it activated the first time without having to do the phone activation, any further installs will too.

Right...as mentioned earlier, in spite of rumored MS horror stories, I've never had an issue with them.

Hey, on another note, if you get a spare moment please take a look at a thread we created over in the

Hardware Dept. and give your opinion-

Samsung 850 PRO 256GB Anomalies

Thanks!

I have absolutely no experience with that type of program. And in all likely hood wouldn't use it anyway. I'm not a big believer in those types of utilities.

Actually, it came with the SSD... it's merely a performance monitor, so to speak. It was the read/write

values I was seeking an opinion on. They're not the same as they were when I installed the SSD 11/2015.

As far as tweaking, performance, registry cleaners and utilities, I stay away from those, too.

Except CCleaner.
