Windows 10: BSOD after downgrade to Win 10?

Hello everyone! Today I updated my PC to Windows 11. After having a look I decided it ultimately wasn't for me and downgraded back to Windows 10. When my PC first started on Win10 again it was incredibly slow and then after about a minute I got a BSOD. The PC restarted by itself and now works fine, but I am a little wary. Is this a common issue after downgrading back to Win 10? The bugcheck code is 0x0000001a 0x0000000000061941, 0x00000132073467c0, 0x000000000000000d, 0xfffffe039643fac0 and I've uploaded the dmp file hopefully correctly here: https://drive.google.com/file/d/14-XH_QEEoWseKss

Hi,

You can downgrade it, BUT:

As it is an OEM preinstalled operating system Windows 10 Pro, you will have to contact Lenovo and discuss this with them.

@@@@@@@@@@@@@@@@@@@@@@@@@@

Here is the information about Downgrade rights. It is an old Microsoft link which they removed but the information still apples>

Device Partner Center

Downgrade rights for Windows software
The following OEM versions of Windows software are eligible for downgrade rights.

[table][tr][td]Windows 10 Pro includes downgrade rights to:

• Windows 8.1 Pro
• Windows 7 Professional

[/td][td]Windows 8.1 Pro includes downgrade rights to:

• Windows 7 Professional
• Windows Vista Business

[/td][td]Windows 7 Professional and Windows 7 Ultimate include downgrade rights to:

• Windows Vista Business and Windows Vista Ultimate
• Windows XP Professional, Windows XP Tablet PC Edition, or Windows XP x64 Edition

Note Other OEM Windows 7 versions (for example, Windows 7 Home Basic and Windows 7 Home Premium) do not include downgrade rights.[/td][/tr][/table]

Note downgrade rights are only available as long as Microsoft provides support for that earlier version,
as outlined in the
Windows lifecycle fact sheet.

Steps for an end user to downgrade Windows software
To downgrade eligible Windows software, end users must:

• Purchase a PC preinstalled with Windows software.
• Accept the Microsoft Software License Terms.
• Perform the downgrade process to the eligible downgrade product using the media/key from a genuine, previously licensed OEM or retail product.

Windows downgrade rights ]

To use prior versions of Windows software on PCs installed with newer versions, it is possible for consumers to obtain a license for downgrade rights. These downgrade rights will vary depending on whether the software was acquired via Volume Licensing,
OEM, or FPP. To learn more about these rights, review the
downgrade rights licensing brief. Prior versions of Windows, including Windows 7 and Windows 8.1, have limited support when running on new processors and chipsets from manufacturers like Intel, AMD, NVidia, and Qualcomm.
For more information, please see the Microsoft Lifecycle FAQ. A device may not be able to run prior versions of Windows if the
device hardware is incompatible, lacks current drivers, or is otherwise outside of the original equipment manufacturer’s (OEM) support period.

Cheers.

I just reran the Media Creation Tool that I just downloaded a few minutes ago. It took less than three minutes to create the ISO file on my medium powered computer with NVMe SSD and 500 Mbps internet connection. Maybe try restarting your computer and downloading a fresh Media Creation Tool? Make sure to note where the ISO file is stored at the last step:

Hello there, tom.
I would try these:

• Get your Windows 7 media device and reinstall Windows
• Try auto-repair
• Follow these steps:

1. Put in your Windows 10 media device, boot into the USB
2. Select your language and keyboard input, then click next.
3. Click "Repair this computer"
4. Go to "Advanced options"
5. click system restore
6. Select a restore point before you downgraded to Windows 7.

Hope I helped!
