Beauti OS Custom Windows 11 Installation Guide and Honest Review

Beauti OS is a customised edition of Windows 11 prepared by an independent project — not by Microsoft. Builds like this are typically made by taking Microsoft's Windows 11 installation image, restyling the interface (themes, icons, layouts), adjusting settings and components, and repacking the result as a new ISO file you install like regular Windows.

That means two things at once. The foundation is real Windows 11, so your normal apps and drivers work the way you expect. But the finished product was assembled by a third party, on their choices, and Microsoft never tested, approved or released it. Keep that sentence in mind through every section below.

A custom OS install wipes the machine it lands on. Treat it with the same respect as major surgery:

1. Use a spare or test PC. Never your only computer, never the machine your job, studies or banking depend on
2. Back up everything first — documents, photos, browser data — to an external drive or cloud storage that will not be touched during the install
3. Keep a genuine Windows 11 USB ready. If you dislike the result, your way back is a clean install of stock Windows (the full exit route has its own guide on this site)
4. Download the ISO only from the source the video points to. Custom Windows ISOs are a favourite hiding place for malware — a copy re-uploaded by strangers is a gamble, and a checksum only proves a file matches what the uploader published, not that it is clean
5. Have your genuine Windows licence key noted down. A custom build does not include a licence — more on this in the activation guide

The install itself follows the familiar Windows setup flow, exactly as shown in the video:

1. Download the Beauti OS ISO from the source given in the video description
2. Create a bootable USB from the ISO — a tool like Rufus or Ventoy does this; the drive will be erased, so use a spare pendrive
3. Boot the target PC from the USB (open the boot menu at startup — usually F12, F8 or Esc depending on the brand)
4. Choose the drive or partition to install on. This erases it completely — double-check you picked the right one
5. Follow the setup screens: region, keyboard, account and privacy choices
6. On the desktop, install your motherboard, graphics and network drivers from the PC or laptop maker's official site — custom builds do not always carry the right drivers for your exact hardware
7. Install your apps, restore your files from the backup, and spend a day testing everything you rely on — sound, Wi-Fi, printing, Bluetooth — before trusting the machine

Before you settle in, run these three quick verifications:

1. Activation status: open Command Prompt and run slmgr.vbs /xpr — it tells you plainly whether Windows considers itself activated
2. Security status: open Windows Security and confirm an antivirus is present and switched on. Some modified builds in the wild weaken or strip protection — if yours has none, treat that as a serious warning sign, not a feature
3. Update status: run Windows Update once and note what happens. On custom builds, updates are the fragile part — you want to learn that on day one, not month six (full details in the updates guide)
