What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Rufus does not disable, remove, or emulate your computer’s TPM. It creates Windows 11 installation media that tells Windows Setup to skip the TPM 2.0 and Secure Boot checks. The dependable method is to boot the target computer from that USB and perform a clean installation. Microsoft considers hardware that fails its requirements unsupported, so back up your data and understand the update, driver, warranty, and compatibility risks before continuing.
What Rufus changes—and what it does not
TPM is a firmware or hardware security component. On Intel systems it may be called PTT; on AMD systems it is commonly fTPM. Other firmware labels include TPM Device and Security Device Support.
Rufus changes the Windows installation environment on the USB. Its Windows User Experience dialog can add Setup bypasses such as BypassTPMCheck and BypassSecureBootCheck, as documented in the Rufus FAQ. Your firmware TPM setting remains unchanged.
Check whether TPM can simply be enabled
- Press Windows + R, type
tpm.msc, and press Enter. - Check whether Windows detects a TPM and reports specification version 2.0.
- If none is found, restart and enter UEFI/BIOS setup.
- Look for Intel PTT, AMD fTPM, TPM Device, Security Device Support, or a similar setting. Enable it, save, and check again.
Enabling an existing TPM is preferable because it keeps the computer within Microsoft’s supported hardware configuration. Firmware menu names and locations vary by manufacturer; there is no universal BIOS path. Microsoft’s minimum requirement is described in its Windows 11 hardware requirements.

Before you create the USB
- Back up everything: a clean installation can remove personal files, applications, profiles, recovery partitions, vendor utilities, and boot configuration.
- Save encryption keys: export your BitLocker or device-encryption recovery key before changing firmware or reinstalling.
- Use a blank USB: Rufus formats the selected drive. Verify its capacity and contents; choosing the wrong device can erase another disk.
- Have a license: activation requires a valid product key or digital entitlement.
- Confirm hardware basics: bypassing TPM does not bypass storage, memory, CPU-instruction, graphics, firmware, driver, or performance limitations.
- Prepare boot access: find your computer’s one-time boot-menu key and confirm it can boot from USB.
Download Rufus and an official Windows 11 ISO
Download Rufus only from rufus.ie or its official downloads directory. The site listed Rufus 4.15, released June 30, 2026, as the latest release during the current documentation period. Most Intel- and AMD-based PCs need the Windows x64 build; the portable edition does not require installation.
Get the ISO from Microsoft’s Windows 11 download page. Microsoft currently identifies Windows 11 2025 Update, version 25H2, as its current release. Select the requested language; the multi-edition ISO uses your product key or digital license to select the applicable edition. Avoid modified third-party images and verify the download when possible.
Create the Rufus USB with the TPM bypass
- Insert the blank USB drive and start Rufus. Approve administrator access if Windows requests it.
- Confirm Device names the intended USB.
- Set Boot selection to Disk or ISO image, click SELECT, and open the Windows 11 ISO.
- For a modern UEFI computer, choose GPT for Partition scheme and UEFI for Target system. Use MBR/BIOS only when the target computer requires legacy booting. If unsure, check the manufacturer’s documentation.
- Click Start. Rufus may open a Windows User Experience dialog.
- Select the option whose wording removes the Windows 11 requirements for TPM 2.0 and Secure Boot. Older releases have shown wording such as “Remove requirement for 4GB+ RAM, Secure Boot and TPM 2.0.” Labels and available checkboxes vary with Rufus and the ISO. Select a 4 GB RAM bypass only when you understand the performance implications.
- Confirm the erase warning and wait for Rufus to finish.
The bypass is applied to this installation media; it does not permanently change TPM or Secure Boot in firmware.
Rank #2
- High-speed USB 3.0 performance of up to 150MB/s(1) [(1) Write to drive up to 15x faster than standard USB 2.0 drives (4MB/s); varies by drive capacity. Up to 150MB/s read speed.

Boot the target PC from the USB
- Leave the USB connected and restart the target computer.
- Open the one-time boot menu. Common keys include F12, F9, Esc, or a manufacturer-specific key.
- Choose the USB, preferably its explicit UEFI entry when two entries appear.
- Start Windows Setup from the USB.
Do not open the USB in File Explorer and run setup.exe if your goal is Rufus’s normal TPM bypass. Rufus documents that bypass as applying when the computer boots from the created media, not as a general in-place-upgrade switch. See the Rufus upgrade FAQ.
Install Windows 11 without deleting the wrong disk
- In Setup, choose Custom: Install Windows only for a clean installation.
- Identify the target disk by capacity and existing layout before deleting or formatting anything.
- Delete or format partitions only after confirming your backup. Disconnecting unrelated internal drives is a useful precaution against selecting the wrong disk.
- When replacing an old Windows installation, leaving the target disk unallocated lets Setup create its required partitions automatically.
A clean install removes the old Windows environment. It is not the same as preserving applications and files through an in-place upgrade.
Finish with post-install checks
- Run Windows Update.
- Install missing drivers from Windows Update and, when necessary, the computer manufacturer.
- Open Device Manager and investigate unknown devices.
- Check Settings > System > Activation.
- Test networking, audio, graphics, sleep, Wi-Fi, Bluetooth, storage, Windows Hello, and your essential applications.
- Review firmware security settings after installation; do not change Secure Boot or TPM settings without confirming that your boot configuration supports the change.
What this bypass cannot guarantee
Rufus’s TPM option is not a universal Windows 11 compatibility bypass. Remaining barriers can include:

- A system too slow for acceptable daily use.
- Firmware that cannot boot the selected GPT/UEFI or MBR/BIOS layout.
- Setup changes tied to a particular Windows release.
For Windows 11 24H2 and later, SSE4.2 and POPCNT can be hard CPU requirements. Rufus states that systems lacking critical instruction support cannot be made compatible through a simple installer bypass; it also warns that bypassing memory or storage requirements can cause crashes, poor performance, or unresolved update issues. See the current Rufus FAQ.
Clean install versus in-place upgrade
| Path | How it works | What to expect |
|---|---|---|
| Boot from Rufus USB | Start the PC from the created media and run Windows Setup. | The documented TPM/Secure Boot bypass is intended for this clean-install route; existing apps and files are normally removed if you format the system partition. |
Run setup.exe inside Windows |
Launch Setup from the existing installation. | The standard Rufus bypass does not automatically apply. Newer Rufus versions have separate, version- and ISO-dependent handling for some 24H2 in-place restrictions, but it is not equivalent to the basic USB procedure. |
Troubleshooting
The bypass option is missing
Click Start first; the controls are in the Windows User Experience dialog, not the main window. The ISO must be recognized as a Windows image, and Rufus must run on Windows 8 or later. Rufus or the ISO version may also change the wording and available options.
Setup still reports unsupported hardware
- Confirm you booted the USB rather than launching
setup.exe. - Recheck that the correct USB was selected in the boot menu.
- Use an official Windows 11 ISO and recreate the drive if Rufus reported an error.
- Check for a CPU-instruction, RAM, storage, driver, or firmware failure unrelated to TPM.
The computer starts the old Windows installation
The internal disk was probably selected, the boot order did not change, or the USB’s boot mode does not match the firmware. Recreate the media with the appropriate partition scheme and select the explicit UEFI USB entry when available.

The USB is not visible
Try another port (a rear motherboard port on a desktop), another flash drive, or a freshly recreated USB. Check that USB boot is enabled in firmware. Do not automatically disable Secure Boot: some systems boot the media with it enabled, while others may require a temporary change depending on the bootloader and firmware. Rufus discusses these variations in its FAQ.
Windows 11 25H2 shows a boot or Secure Boot certificate error
Rufus documents an advanced Windows UEFI CA 2023 case for systems where the older PCA 2011 certificate has been revoked. Rufus 4.10 or later can create media with CA 2023-signed bootloaders, but the procedure requires a compatible Windows 11 25H2 ISO; the FAQ says a 24H2 ISO does not work for that specific scenario.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Support and update risks
Microsoft requires TPM 2.0 for supported Windows 11 hardware. Its download page warns that installing on ineligible devices can cause compatibility problems, loss of support, warranty limitations, and no entitlement to updates. Windows Update may work, but neither feature updates nor monthly updates are guaranteed on unsupported hardware.

Safer alternatives
- Enable Intel PTT, AMD fTPM, or another firmware TPM when available.
- Use Microsoft’s Installation Assistant, Media Creation Tool, or ISO on compliant hardware.
- Keep the computer on Windows 10 when Windows 11 performance or compatibility is unacceptable; support dates depend on your edition and licensing situation.
- Consider Linux or another lightweight operating system if keeping the hardware useful matters more than running Windows 11 specifically.
- Upgrade or replace the computer when CPU instructions, firmware, drivers, or performance are fundamentally inadequate. Microsoft’s PC Health Check guidance outlines these options.
Frequently Asked Questions
Does Rufus disable TPM?
No. Rufus modifies Windows installation media so Setup skips selected checks. It does not disable, remove, or emulate the TPM in your computer.
Can I keep my files and applications?
The standard Rufus bypass is intended for booting from USB and performing a clean installation. That path can remove files, applications, profiles, and recovery partitions. An in-place upgrade is a separate scenario and the normal bypass does not automatically apply to it.
Will Windows Update continue to work?
It may, but Microsoft does not guarantee updates or support for installations on hardware that fails Windows 11 requirements.
Do I need to disable Secure Boot?
Not always. Whether it is necessary depends on the firmware, bootloader signing, ISO, and boot path. Try the created media with Secure Boot enabled before changing firmware settings.
Crashes, No Sound, or Screen Glitches?
Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteWindows Errors? Fix Them Before They Spread
Repair common Windows errors and clear accumulated junk for a smoother, more stable PC - no reinstall needed.Free scan · no reinstallCan this bypass CPU requirements?
Not reliably. CPU architecture and required instructions such as SSE4.2 and POPCNT can remain hard limits, and Rufus does not promise a universal CPU bypass.
What if the PC has no TPM at all?
The USB method may let Windows Setup proceed, but the resulting installation remains unsupported and can still fail other hardware, driver, performance, or update requirements.
