Locked out of brand-new laptop

Yes — a clean reinstall from USB should work, and the laptop will not be “re-locked” just because Microsoft knows that hardware already exists.
The short version:

• Windows activation and Windows sign-in account/PIN are separate things.
• Reinstalling Windows wipes the old sign-in setup on the drive.
• If you reinstall the same Windows edition that came with the laptop, Windows should normally reactivate automatically once online. Microsoft says that if a device already has a digital license, you can reinstall the same edition without entering a product key, and activation should happen automatically after install. It also says that during reinstall you can choose “I don’t have a product key.” citeturn0commentaryto=multi_tool_use.parallel0
• Microsoft also says they cannot recover a lost BitLocker key for you. If the key is unknown and the old install is unrecoverable, reset/reinstall is the practical path. citeturn0commentaryto=multi_tool_use.parallel0

A few important details:

1) The unknown Microsoft account is only a problem for the current install​

Right now the temp staffer likely set up:

• a Microsoft account,
• a PIN,
• and possibly automatic device encryption / BitLocker.

That affects the current Windows installation. It does not create a permanent cloud lock on the hardware in the normal consumer sense.

2) BitLocker matters if you try to recover the existing install​

Microsoft’s guidance is that the recovery key may be stored in the Microsoft account that enabled BitLocker, and if someone else set up the device, the key may be in that person’s account. citeturn0commentaryto=multi_tool_use.parallel0
So:

• If you try Reset this PC from the existing encrypted install, it may keep asking for the BitLocker key.
• If you boot from a Windows 11 installation USB and do a clean install, deleting the existing partitions, you generally sidestep the need to unlock the old installation first because you’re replacing it rather than opening it.

3) Activation should be the easy part​

Microsoft states:

• if Windows was already activated with a digital license, reinstalling the same edition should activate automatically after install,
• and on reinstall you can skip product-key entry with “I don’t have a product key.” citeturn0commentaryto=multi_tool_use.parallel0

For an ASUS laptop sold with Windows 11, that usually means:

• the license is OEM/digital,
• Setup detects the edition automatically,
• and activation happens once it gets online.

So no, it should not “phone home and rediscover the temp’s account” and force that account back onto the machine. Activation is tied to license/hardware; sign-in is a separate setup choice. citeturn0commentaryto=multi_tool_use.parallel0

What I’d recommend​

Best plan​

Create the USB yourself and mail it to him, then talk him through:

1. Boot from the USB
2. Choose Install Windows 11
3. If asked for a key, choose I don’t have a product key
4. When you reach the disk/partition screen, choose Custom
5. Delete all existing partitions on the internal drive
6. Install to the unallocated space

That will give him a truly fresh start.

Two cautions​

A) OOBE/account setup may still be the hardest part​

The reinstall is only half the battle. Since your brother is struggling cognitively, the new-account setup may again be the weak point.
You may want to decide in advance:

• what Microsoft account will be used,
• what password it will have,
• what recovery phone/email it will use,
• and who keeps the record.

Because Microsoft notes that BitLocker recovery may be backed up to the Microsoft account used with the device. citeturn0commentaryto=multi_tool_use.parallel0
If the machine signs into a Microsoft account again and device encryption turns on, you want that recovery path under your family’s control, not another random helper’s.

B) If this was somehow organization-managed​

In the uncommon case the temp enrolled it in a work/school environment, that can complicate setup. Microsoft notes recovery keys can also live in a work or school account if the device was joined to one. citeturn0commentaryto=multi_tool_use.parallel0
That said, on a consumer ASUS Vivobook bought retail and shipped new, I think that’s less likely than “temp used his own Microsoft account.”

My practical advice​

Given:

• no data to preserve,
• unknown PIN,
• unknown Microsoft account,
• unknown BitLocker key,

a clean USB reinstall is the right move.
If you want, I can give you a very literal phone script for your brother:

• how to boot the ASUS from USB,
• exactly what wording to look for,
• and exactly which buttons/options to choose.

Yes please, I would like a literal phone script.

Absolutely, torch. Here is a literal phone script you can read to your brother.
Microsoft says a Windows USB installer can be used to install a new copy of Windows or perform a clean install, and if the laptop already has the correct digital license, Windows should usually reactivate automatically online after reinstall. ASUS also says that on notebooks, the normal way to boot from USB is to hold Esc while pressing Power to open the Boot Menu.

Before you call him​

Please have these ready on your end:

1. A Windows 11 USB installer you created with Microsoft’s media creation tool.
2. A note that says “Choose Windows 11 Home” if the installer asks for edition, unless the laptop was definitely sold with Pro. Microsoft says the reinstalled edition must match the device’s license.
3. The Microsoft account details you actually want him to use later.
4. A warning for him: this will erase everything on the laptop.

Literal phone script​

Part 1: Getting to the USB boot menu​

Read this slowly, one line at a time:

1. “Please shut the laptop all the way off.”
2. “Put the USB stick into the laptop now.”
3. “Put one finger on the Esc key and keep it there.”
4. “While holding Esc, press the power button once.”
5. “Keep holding Esc until you see a boot menu.”

ASUS’s official instructions say to hold Esc and press Power to enter the Boot Menu on notebooks, then select the USB device and press Enter. (asus.com)
If he gets the boot menu:

1. “Use the arrow keys to highlight the USB drive.”
2. “Press Enter.”

If he does not get the boot menu:

1. “Turn it off again.”
2. “This time, tap F2 repeatedly right after pressing Power.”
3. “Tell me if you see a blue, gray, or black setup screen.”

ASUS says that if Esc does not open the boot menu, use the BIOS method instead; from BIOS, ASUS says you can use F8 for Boot Menu on supported UEFI screens. (asus.com)
If he reaches BIOS:

1. “Press F8 once.”
2. “If you now see the USB drive, highlight it and press Enter.”

If the USB still does not appear, stop there and reply back here — at that point the next step is BIOS settings like Fast Boot or Secure Boot, which ASUS documents, but I would only use those if needed. (asus.com)

Part 2: Starting Windows Setup​

Once Windows Setup appears, say:

1. “Do you see a Windows setup screen asking for language and keyboard?”
2. “Just leave the default choices alone unless something looks obviously wrong.”
3. “Click Next.”
4. “Click Install now.”

If it asks for a product key:

1. “Click I don’t have a product key.”

Microsoft says during reinstallation you can choose “I don’t have a product key”, and Windows should activate automatically later if the license already belongs to that hardware and the edition matches.
If it asks which edition to install:

1. “If you see Windows 11 Home, choose that.”
2. “Only choose Pro if the laptop definitely came with Pro.”
3. “Then click Next.”

Microsoft says the reinstalled Windows edition must match the existing license on the device.

Part 3: The wipe-and-reinstall part​

Read this carefully:

1. “If you see a license agreement, check the box and click Next.”
2. “If you are asked Upgrade or Custom, choose Custom: Install Windows only.”
3. “Now you should see a list of drive partitions.”
4. “We are going to erase the whole internal drive.”
5. “Click the first partition, then click Delete.”
6. “If it asks to confirm, click OK.”
7. “Repeat that for every partition on the internal drive until there is only one big area called Unallocated Space.”
8. “When only Unallocated Space is left, click it once.”
9. “Now click Next.”

This is the clean-install portion. Microsoft’s installation media is specifically meant for a clean install/new copy of Windows, and since you said there is no data to save, this is the right path.

---

Part 4: Waiting through the install​

Say:

1. “Now leave it alone while Windows copies files.”
2. “The laptop may restart several times. That is normal.”
3. “Do not press any keys unless I tell you to.”

If it reboots and goes back to the first Windows installer screen again:

1. “Pull out the USB stick now.”
2. “If needed, restart once more.”

---

Part 5: First-time setup after install​

This is the part where I would be careful, because you do not want another random person creating another mystery account.
Tell him this:

1. “When you get to the first questions after installation, stop and read each screen to me.”
2. “Do not let anyone else invent an email address, password, PIN, or phone number.”
3. “If it asks to connect to Wi-Fi, that is fine, but stop before entering any Microsoft account unless we already agreed on exactly which one to use.”

Microsoft notes that BitLocker recovery information can be tied to the Microsoft account used on the device, so it is important that the account and recovery details are under family control this time. It also notes that if someone else set up the device, the old BitLocker recovery key may be in that other person’s Microsoft account.

Short fallback script if he gets confused​

If he is struggling, use this very short version:

1. “Hold Esc and press Power.”
2. “Choose the USB stick and press Enter.”
3. “Click Install now.”
4. “If asked for a key, click I don’t have a product key.”
5. “Choose Windows 11 Home if asked.”
6. “Choose Custom.”
7. “Delete every partition.”
8. “Click the big Unallocated Space.”
9. “Click Next.”
10. “When the setup finishes, stop and call me before making any account.”

If you want, I can also give you​

1. a one-page printable checklist for you to read during the call, or
2. a “what if he sees X?” troubleshooting sheet for things like:

• USB not showing up
• boot menu not opening
• installer asking about Wi-Fi
• edition choice confusion
• trackpad not working during setup
