Microsoft OEM System Builder | Windоws 11 Pro | Intended use for new systems | Authorized by Microsoft

Product is exactly what was advertised. Remember its mounts on a new system and can only be used on that system. You can go to Microsoft store pay more but that includes tech support and being able to mount this windows Pro on a couple more times! I purchased a Lenovo ThinkCentre Micro Desktop with Keyboard & Mouse, 16GB DDR4 RAM, 1TB SSD Drive and I could never get windows to boot. It was locked at login telling me that it was not a new unit. I went into the bios and low and behold it was from late 2024. So I could use it I loaded Mint Linux and Ubuntu on same drive so I could use it and decided to get new ssd and a new windows operating system. As I write these words I am creating a recovery drive if I ever need to restore!

I purchased and used this disk to install Windows 11 Pro on my latest build. I had no issues. I used a portable DVD drive to do the install. Everything is working well. I will say that Windows 11 Pro has some quirks to it that, coming from Windows 10, really makes me scratch my head wondering "What were they thinking!". I actually prepared a document of my experiences in case I ever had to do it again. A month later we decided to upgrade my wife's laptop from Windows 10 to Windows 11, and I got to again employ many of the items identified in my earlier document. I have nothing against using OS downloads rather than an installation DVD, but I don't have any USB drives of sufficient capacity to hold an OS installation image, and I couldn't find any I thought reliable.

This product was used on two home-built ASUS desktops and an ASUS Vivobook notebook computer. I make my computers to be dual boot; Windows (whatever version) and Linux (Mint). The way I switch operating systems is to shut down the computer, access the UEFI (BIOS), and change to the SSD or the partition of the operating system I want to use. This worked fine. I have done this sort of thing for years, dating back to Windows XP. Most of the time I leave these three computers running all the time under Windows (11). One morning last August (2024), I find all three computers were alive in Linux. I shut down and switched back to Windows, and the computers completed a compulsory update. Days later I try to switch to Linux to do (my) scheduled updates. Microsoft has locked me out of the UEFIs, so I cannot switch operating systems. Just swell. I can work around this with the desktop systems, but it is a Royal Pain. I have to get in the box, then pry out the lithium battery for the realtime clock and BIOS. After the BIOS' brains are scrambled, I reassemble the machine, set the clock, fix the "secure boot" vandalism, and switch (or not switch) operating systems. This works fine until Microsoft gets their tentacles on the computers again, via mandatory update. The notebook computer is another catastrophe. Getting inside is the thing is not much fun. I cannot find a lithium battery to pop out. It might not have one. I have an old HP money pit notebook that when you unplug the main battery, the BIOS wakes up says "Where the heck am I?" The ASUS Vivobook has no such feature. I have unplugged the battery overnight, and it still doesn't let go. The only way I can regain control is to unplug the SSD, and start the machine up without an SSD. That gets the BIOS' attention. I leave this computer running Linux. Someday, when I have time, I will rework the SSD to make it all Linux. The Vivobook has only one SSD. That is another joy brought to me from the Benevolent System "Administrators" of Microsoft. They will no longer allow me to back up Windows on another SSD. I have a 2 TB SSD, half Windows/half Linux. It looks like the only solution is Wipe the SSD and reinstall Linux on the entire 2 TB. Remember this when you contemplate buying your next Microsoft product. You think you own it, but do you really? Oh yeah, you pay for it. When it breaks you fix it, replace it, or junk it. But if you use it in a way that Microsoft does not approve, they will "fix" it for you. After all, they can do that. You really don't own it.

It works. I just needed the key. You can download the OS from Microsoft for free and put it on a USB drive. Who puts a DVD drive in a new build in 2026? I have a portable USB DVD drive but doing it that way didn't want to work for me. Downloading a copy and putting it on a thumbdrive is easy.

great product I dont think I need it

Funktioniert problemlos, toller und schneller Service Die Software muss man sich natürlich über Microsoft runterladen.

I like it. It is working well. Not one single glitch.

I set a new windows for my brand new build with this disk and its genuine and it's also includes activation key in it though it require a external cd drive but it was really compatibe with my msi pro and smooth running so I think it's must bought for new build

Totalmente original

Easy to install. perfect if you've a customised pc
