Remove the Windows.old folder manually

Windows creates the folder Windows.old on a PC running Windows when you upgrade the PC to a new version of the operating system.
The Windows.old folder contains files and folders of the old installation of Windows, and the main reason it is there is that it is used to restore the old system if the user wants to go back to it.
This folder may take up a sizeable amount of space, but will get deleted automatically usually by Windows after a set period of time.
Windows users may also use the disk cleanup tool to remove the folder as described here. Sometimes however it happens that the folder and its content is not removed, and that a manual removal does not work either.
When you try to delete the folder manually in Explorer, you get permission errors as the folder is associated with SYSTEM and not a user or administrator account.
What happens usually is that you get a permission request first to run the operation with administrative privileges, and then the Folder Access Denied error.
Remove the Windows.old folder manually
You need to run the following commands remove the Windows.old folder manually.
- Open an elevated command prompt. EAsiest way to do so is to tap on Windows, type cmd.exe, hold down the Shift-key and the Ctrl-key, and launch the elevated command prompt with a tap on the Enter-key.
- takeown /F c:\Windows.old\* /R /A /D Y
- cacls c:\Windows.old\*.* /T /grant administrators:F
- rmdir /S /Q c:\Windows.old
Lets take a closer look at the commands to better understand what they do:
takeown /f c:\Windows.old\* /r /a /d y
Takeown can be used to make the administrators group the owner of a file or directory.
- /f c:\Windows.old\* -- This specifies the location and files that the operation will be run on.
- -r -- performs a recursive operation on all files (means all files are included that are in the Windows.old folder).
- -a -- gives ownership to the Administrators group.
- -d Y -- surpresses the confirmation prompt when the current user does not have the "List Folder" permission.
cacls c:\Windows.old\*.* /t /grant administrators:f
This command displays or modifies DACL (discretionary access control list) files.
- c:\Windows.old\*.* -- The files you want the operation to run on.
- /t -- This changes the DACL of the files in the selected directory and all subdirectories.
- /grant administrators:f -- This grants full access rights to the administrators group (The F stands for full)
rmdir /s /q c:\Windows.old
The command removes a directory.
- /s -- this parameter makes the command remove the directory that is specified, and all of its subdirectories and files.
- /q -- runs the program in quiet mode without confirmation prompts.
- c:\Windows.old -- specifies the directory the operation should be run on.

What mental age of reader are you targeting with the first sentence? 10?
Why not write an article on how to *avoid* upgrading from W10 to W11. Analogous to those like me who avoided upgrading from 7 to 10 for as long as possible.
If your paymaster Microsoft permits it, of course.
5. Rufus
6. Ventoy
PS. I hate reading these “SEO optimized” articles.
I used Rufus to create an installer for a 6th gen intel i5 that had MBR. It upgraded using Setup. No issues except for Win 11 always prompting me to replace my local account. Still using Win 10 Pro on all my other PCs to avoid the bullying.
bit pointless to upgrade for the sake of upgrading as you never know when you’ll get locked out because ms might suddenly not provide updates to unsupported systems.
ps…. time travelling?

Anyone willing to downgrade to this awful OS must like inflicting themselves with harm.
I have become convinced now that anybody who has no qualms with using Windows 11/10 must fit into one of the following brackets:
1) Too young to remember a time before W10 and W11 (doesn’t know better)
2) Wants to play the latest games on their PC above anything else (or deeply needs some software which already dropped W7 support)
3) Doesn’t know too much about how computers work, worried that they’d be absolutely lost and in trouble without the “”latest security””
4) Microsoft apologist that tries to justify that the latest “features” and “changes” are actually a good thing, that improve Windows
5) Uses their computer to do a bare minimum of like 3 different things, browse web, check emails, etc, so really doesn’t fuss
Obviously that doesn’t cover everyone, there’s also the category that:
6) Actually liked W7 more than 10, and held out as long as possible before switching, begrudgingly uses 10 now
Have I missed any group off this list?
You have missed in this group just about any professional user that uses business software like CAD programs or ERP Programs which are 99% of all professional users from this list.
Linux doesn’t help anyone who is not a linux kid and apple is just a fancy facebook machine.
Microsoft has removed KB5029351 update
only from windows update though
KB5029351 is still available from the ms update catalog site
1. This update is labaled as PREVIEW if it causes issues to unintelligent people, then they shouldn’t have allowed Preview updates ot install.
2. I have installed it in a 11 years old computer, and no problems at all.
3. Making a big drama over a bluescreen for an updated labeled as preview is ridiculous.
This is probably another BS internet drama where people ran programs and scripts that modified the registry until they broke Windows, just for removing stuff that they weren’t even using just for the sake of it.
Maybe people should stop playing geeks and actually either use Windows 10 or Windows 11, but don’t try to modify things just for the sake of it.
Sometimes removing or stopping things (like defender is a perfect example) only need intelligence, not scripts or 3rd party programs that might mess with windows.
Windows 11 was a pointless release, it was just created because some of the Windows team wanted to boost sales with some sort of new and improved Windows 10. Instead, Microsoft cannot support one version well let alone two.
Windows 11 is the worst ugly shame by Microsoft ever. They should release with every new W11 version a complete free version of Starallback inside just to make this sh** OS functionally again.

While there may be changes or updates to the Windows 10 Store for Business and Education in the future, it is premature to conclude that it will be discontinued based solely on rumors.
My advice, I left win 15 years ago. Now I’m a happy linux user (linuxmint) but there is Centos, Fedora, Ubuntu depending on your needs.
