I'm Dave. I've been building and setting up custom PCs in Somerville, NJ since 2011. This guide covers everything — from creating your bootable USB to getting past Windows setup, including how to skip the Microsoft account requirement during OOBE if you'd rather keep it local.
Get everything on this list together before you touch the BIOS. Missing one item mid-install is the most common reason people get stuck.
Do this on a working PC before you touch your new build. Takes about 10–15 minutes depending on your USB write speed.
Go to rufus.ie and download the latest version. No install needed — just run it. Plug in your USB drive. Rufus will detect it automatically.
In Rufus, click the SELECT button and navigate to the Windows 11 ISO you downloaded from Microsoft. Rufus will auto-configure most settings once it reads the ISO.
When Rufus asks about "Windows User Experience," you'll see checkboxes including "Remove requirement for an online Microsoft account." Check this box if you want to create a local account during setup. This is the cleanest and most reliable bypass method — it bakes the skip directly into the installer before Windows even starts. See full bypass method details in Section 5 below.
Rufus will warn you that all data on the USB will be destroyed. Confirm and let it run. The write process takes 5–15 minutes. When it shows READY at the bottom, the USB is done. Safely eject it.
This is where most first-time builders get stuck. Windows 11 requires specific BIOS settings to install. Get these right first.
Find the boot settings in your BIOS and make sure UEFI mode is selected. Disable CSM (Compatibility Support Module) or Legacy Boot if it's present. Windows 11 requires UEFI. If CSM is enabled, Secure Boot and TPM may be hidden or non-functional.
Find Secure Boot and set it to Enabled. Windows 11 requires it. If Secure Boot is grayed out, CSM is likely still enabled — disable CSM first, then come back. On some boards you'll also need to be in "Standard" mode, not "Custom."
Windows 11 requires TPM 2.0. On Intel boards look for Intel PTT (Platform Trust Technology) — enable it. On AMD boards look for AMD fTPM (Firmware TPM) — enable it. These are software-based TPM solutions built into the CPU and are available on most hardware from 2016 onward.
This isn't required for Windows to install, but your RAM is almost certainly running at 2133MHz by default instead of its rated speed. Find XMP (Intel) or EXPO (AMD) in BIOS — usually on the main page or under AI Tweaker / D.O.C.P. — and enable it. One click, big difference.
In the Boot tab, move your USB drive to the top of the boot order. Save settings and exit (usually F10). The PC will reboot and should start loading from the USB. If it boots into a "no OS found" screen, the USB wasn't created correctly or isn't being recognized.
Once you boot from the USB, the installer takes over. Here's what each screen means and what to actually click.
Leave these as default for most US installs. Click Next, then Install now.
If you have a retail key, enter it now. If you're planning to activate digitally later (reusing a license tied to a Microsoft account) or you'll activate after setup, click "I don't have a product key." You won't lose functionality during install — activation can happen any time after.
Choose Windows 11 Home for most personal or gaming builds. Choose Windows 11 Pro if you need BitLocker, Remote Desktop hosting, Hyper-V, or domain join. Your product key determines which edition activates — if you skip the key, pick the edition that matches what you purchased.
On the installation type screen, choose Custom — not Upgrade. You're doing a clean install on a new build. Upgrade is for keeping files and apps from an existing Windows installation.
You'll see a list of drives and partitions. For a brand new NVMe SSD with no existing data, select the drive (it will show "Unallocated Space") and click Next. Windows will create the required partitions automatically. Don't manually create partitions unless you have a specific reason.
Drive not showing up? Some NVMe drives require a storage driver to be loaded during setup. Click Load driver, point it to the driver files (on a second USB), and your drive will appear. Check your motherboard manufacturer's site for the appropriate Intel RST or AMD RAID/AHCI driver.
Windows copies files, expands them, installs features, and reboots several times. Don't touch anything. When it reboots, it will load from the hard drive automatically (not the USB again) — that's normal. Eventually it will land on the OOBE screen.
Windows 11 will push hard to get you to sign in with a Microsoft account during OOBE. You don't have to. Here are every method that still works as of 2025 — ordered from easiest to most involved.
Works on: All Windows 11 versions including 24H2 and 25H2. Most future-proof option.
Works on: Windows 11 Pro, all builds. Does not work on Home edition.
Works on: Windows 11 Home and Pro, most builds as of mid-2025. May stop working in future updates.
shutdown /r /t 0 and press Enter to rebootWorks on: All Windows 11 editions including S Mode and 25H2 Preview builds. Cannot be used from the network or Microsoft account screen.
Getting Windows installed is half the job. A fresh install with no drivers is missing critical functionality. Here's what to do in the first 30 minutes on the desktop.
Go to Settings → Windows Update → Check for updates and let it run completely, including optional updates. This pulls in many device drivers automatically and patches security vulnerabilities in the fresh install. Reboot when prompted.
Don't rely on the generic Windows display driver. Download the latest driver for your specific GPU from nvidia.com/drivers or amd.com/support. For NVIDIA, use the "Game Ready" driver. For AMD, use Adrenalin software. Run the installer, reboot.
Go to your motherboard manufacturer's support page, enter your model number, and download the chipset driver. For Intel boards, this is the Intel Chipset Device Software. For AMD boards, this is the AMD Chipset Drivers package. These improve USB controller performance, storage controller behavior, and power management.
Most modern builds get audio and network drivers through Windows Update. But if you have no sound or no network, grab the drivers from your motherboard manufacturer's support page. Look for Realtek Audio, Intel LAN, or whatever chipsets your board uses. The manual will list them.
If you skipped XMP/EXPO during the BIOS setup, go back now. After enabling it and rebooting, verify in Windows: press Ctrl + Shift + Esc → Performance tab → Memory. The "Speed" shown should match your RAM's rated speed. If it shows 2133MHz on DDR5-6000, XMP/EXPO is still disabled.
Go to Settings → System → Activation. If you entered a retail key during install, it should show as activated. If you linked a digital license to your Microsoft account on previous hardware, sign in to activate. If it's not activating automatically, use "Change product key" and enter your key manually.

"Bought all my parts and had no idea how to get Windows installed. Dave's set the whole thing up — BIOS, Windows, drivers, everything. Picked it up ready to go. Worth every dollar."
"Tried to install Windows myself and kept getting stuck at the Microsoft account screen. Used the WinJS trick from this guide and it worked perfectly. Finally have a clean local account setup."
"NVMe drive wasn't showing up during install — brought it to Dave's, they loaded the right driver in five minutes and got Windows on it same day. Saved me hours of frustration."
After building and setting up hundreds of custom PCs at our Somerville shop, here are the problems we see most often.
Easily the most common oversight on new builds. DDR5-6000 kits sitting at 2133MHz because XMP was never enabled in BIOS. One toggle, free performance boost. We check this on every build we set up.
Builders who've worked on older hardware sometimes leave CSM on out of habit. This hides or disables Secure Boot and TPM 2.0 in BIOS, which blocks Windows 11 from installing correctly. Disable CSM first, then enable Secure Boot and TPM.
Some Intel 12th/13th gen builds and certain AMD 500-series boards need an Intel RST or AMD RAID driver loaded during Windows setup for the NVMe drive to appear. Without it, the drive list is blank and people assume the SSD is dead. It's not — it just needs a driver.
Entering a Home key when Windows 11 Pro is selected (or vice versa) causes activation to silently fail. The key doesn't error out immediately — it just doesn't activate. If your key isn't working, verify you're on the correct edition in Settings → System → Activation.

Common questions we get from customers building their first PC or setting up Windows in New Jersey.
Yes, but the old OOBE\BYPASSNRO command no longer works in Windows 11 25H2 and later. The methods that still work: the Rufus "Remove Microsoft account" checkbox (best option — do it before install), Domain Join (Pro only), the Registry BypassNRO command via Shift+F10, and the WinJS Developer Console method. All four are covered in detail in Section 5 of this guide.
Some motherboards require a storage controller driver to be loaded during setup before NVMe drives appear. Click "Load driver" on the drive selection screen and point it to the driver files from your motherboard manufacturer (usually Intel RST for Intel builds or AMD RAID/AHCI for AMD). Put those files on a second USB drive before you start.
For most home users and gamers, Home is sufficient. Pro adds BitLocker full-disk encryption, Remote Desktop hosting, Hyper-V virtualization, and domain join — relevant for work machines or small business builds. Pro also gives you the Domain Join bypass to skip the Microsoft account during OOBE without any commands.

That error means TPM 2.0 or Secure Boot is not enabled in your BIOS. Go back into BIOS: disable CSM, enable Secure Boot (set to Standard mode), and enable Intel PTT or AMD fTPM. Save and retry. If you're on hardware that genuinely doesn't support TPM 2.0 (pre-2016), you can't run Windows 11 officially — you'd need to stay on Windows 10 or use an unofficial workaround.
XMP (Intel) or EXPO (AMD) is not enabled in your BIOS. Your RAM runs at a safe default of 2133MHz until you enable the profile. Go into BIOS → AI Tweaker / D.O.C.P. / AMD Overclocking and enable XMP or EXPO. Save and reboot. Verify the speed in Task Manager → Performance → Memory.
