Hello, I'm Greg, 10 years awarded Windows MVP, here to help you.

Enterprise is a business product not meant for consumer use. It is only legally licensed by a business or organization which uses Volume Licensing administered by an IT department.

So you should ask your IT desk for help with this since they control the Group Policy for the PC.

If you are a consumer then you should install a consumer version such as Home or Pro. You can buy a license here: https://www.microsoft.com/ko-kr/p/windows-10-ho...

Follow the gold standard Clean Install in this link which compiles the best possible Install of Windows which will stay that way as long as you stick with the tools and methods given, has zero reported problems, and is better than any amount of money could buy: https://www.translatetheweb.com/?ref=TVert&...

If someone sold you a PC or license for Enterprise which is not associated with an organization or business then you can report them to Microsoft for software piracy here: https://www.microsoft.com/ko-kr/howtotell/cfr/r...

Feel free to ask any questions. Based on the results you post back I may have other suggestions if necessary.

Hello! I updated(got) my OS version to Pro. But the main problem is that I still cant log in. Is that a bug of Windows 11 in this version?

How exactly did you Upgrade to Pro? This can matter to the install integrity

Failure to sign in can mean a corrupted account or be a fault in your Windows install. I'll give you the repairs necessary when Windows won't start or sign in to try to find and fix the problem:

Use whichever method works in this link to get into Repair Mode so you can try the necessary repairs or do a Reset:
https://www.tenforums.com/tutorials/2294-advanc...

Easiest is to force shutdown by holding in the power button. Do this twice. The third time you power on it should start into Repair Mode. Once in the Repair Mode try the numbered steps below.

It may be necessary to create bootable media on another PC to access Advanced Startup Options to try repairs, a Reset or do the Clean install. The bootable media has it's own set of files so that repairs or Reset might work better, doesn't require a password, and you'll have it to if necessary do the vastly superior Clean Install.

To create Windows 10 Installation Media on another PC install Media Creation Tool and follow the directions here: https://www.microsoft.com/en-US/software-downlo...

Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key given here: https://www.sysnative.com/forums/hardware-tutor...

If the media won't boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first.

Choose the boot device as a UEFI device if offered, on second screen choose Repair Your Computer, then Advanced Troubleshoot Options, then:

1) Try a System Restore, working backward.

2) If that fails try Uninstall Updates as far back as necessary to see if this was caused by an Update. If Steps 1 or 2 get it started then immediately check Windows Update for Updates and hide them using this tool: https://www.tenforums.com/tutorials/8280-hide-s...

3) Open the Command Prompt to:

a) run System File Checker: https://www.wintips.org/how-to-run-sfc-offline-...

and DISM: https://www.ubackup.com/windows-10/dism-offline...

b) run a full Disk Check: https://www.windowsdigitals.com/how-to-run-chkd...

c) trigger Safe Mode with Networking (for internet) or Safe Mode following Option 3 here: https://www.digitalcitizen.life/4-ways-boot-saf... to roll back Updates & Drivers in Windows Update History, update your drivers from the PC/Motherboard manufacturer's website and diagnose further with these steps: https://www.howtogeek.com/164876/how-to-use-saf....

You can also create a new Local Admin account to replace yours: https://www.isumsoft.com/windows-10/3-ways-to-c...

d) To replace the User account try to enable the built-in elevated Admin account from Option Five here:
https://www.tenforums.com/tutorials/2969-enable...

Boot into this emergency Admin account (leaving password box blank) to create a new Local Admin account:
https://www.isumsoft.com/windows-10/3-ways-to-c...

Sign into the new Account, make sure it works correctly, if so move your files over via C:\Users, when ready delete the old account and change the new one to your MS Account if desired in Settings > Accounts > Your Info > Sign in with a MS Account instead.

4) If those fail then go back to Troubleshoot Options to do a Reset. Make it a deep clean reset to set up a new account, with Cloud option to download fresh installation files so it doesn't use old onboard files that may be corrupted.

5) If that fails choose Install Now, then Custom Install, then at the drive selection screen delete all partitions down to Unallocated Space to get it cleanest, click Next to let it create needed partitions and start install - this makes it foolproof. Everything needed to Clean Install is here: http://answers.microsoft.com/en-us/windows/wiki...

6) If you have files that aren't backed up you can use the same bootable media to try to rescue your files using these methods: http://answers.microsoft.com/en-us/windows/wiki...

Your files should be backed up at all times if you value them at all. In the Clean Install tutorial in Step 5 I give the best methods to back up.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

Hi, thx for your answers!

I solved this problem today.

tbh, I just changed the key to change the version.

I solved it by reinstalling (how to say ..hmm.. using the .iso file to achieve an Overridden-style install)

so it might be a system file problem before I do this.
