Can I delete $GetCurrent, $SysReset, $Windows.~WS and $Hyper-V.tmp?

If you check the c: drive on a Windows 10 PC you may notice the hidden folders $GetCurrent, $SysReset, $Windows.~WS and $Hyper-V.tmp sitting there.
Depending on the state of the system, you may also see Windows.~BT listed there. If you don't see these folders, chance is you have not enabled the display of hidden operating system folders on the computer system.
To do that, open File Explorer, and select File > Options from the menu at the top. Switch to the View tab when the Folder Options open, and enable the "show hidden files, folders, and drives" option there.
When you return to the root of drive c:, you may see those folders now. The questions that may come up now are about the purpose of these folders, and whether you can safely delete them to free up disk space or improve usability.
$GetCurrent, $SysReset, $Windows.~WS and $Hyper-V.tmp
First thing you may want to do is check how big those folders are. The $Windows.~WS and $Windows.~BT folders can be quite large -- Gigabytes of data -- which you may need elsewhere.
Simply right-click on one of the folders and select properties from the context menu. Windows highlights the space it occupies on the disk when the properties window opens.
If the folders occupy just a couple of Kilobytes, then you may not want to go through the trouble of deleting them as you won't gain much by it.
Still, if they do occupy a sizeable amount of space, or if you want them gone anyway, read on to find out how to do that.
$Windows.~WS and $Windows.~BT
These two folders are created by Windows during upgrade to a new version. They may occupy a lot of space on the drive.
Microsoft never really released information on these folders, but they are created by Windows during the upgrade process to a new version.
The folders are not use when you run the new version of Windows on the computer, but are required when you decide to roll back the upgrade and return the system to the previous version.
This means, that you should not delete the folders if you a) plan to go back, or b) don't know yet if you need to go back to the previous version.
Note: You can create a system drive backup just in case, and delete the folders once you have done so. This allows you to restore the state before the deletion of the folders, and roll back if the need arises.
You may delete the folders using Disk Cleanup, a built-in tool of the Windows operating system.
- Tap on the Windows-key, type Disk Cleanup, hold down the Shift-key and the Ctrl-key, and hit the Enter-key.
- Locate "temporary Windows installation files" and "previous Windows installation files" there and check the entries. Note the size of them, and check any other item there that you may want to delete.
- Select ok when you are done. Windows may notify you at this point that deleting old Windows installation date will prevent you from going back to the previous version. Accept that, and continue with the deletion of the data.
It is recommended to run this process after the upgrade to a new version of Windows once you know that you won't need to roll back anymore. Check out the guide Free up Gigabytes of disk space after Windows 10 Creators Update installation for additional information on the process.
If you cannot use Disk Cleanup, for instance because it won't delete the folders regardless of what you select, you may delete the folders and files inside manually instead.
Brian N. posted a batch file on the Microsoft Answer site that deletes the folders when run.
@echo off
@echo "This will delete the folder C:\$Windows.~WS and C:\$Windows.~BT after an update to reclaim space. Windows 10 only."
@echo --------------------------------
@echo If you get message "The system cannot find the file specified" it means the folder is already deleted.
@echo --------------------------------
PAUSE
RD /S /Q "C:\$Windows.~WS"
RD /S /Q "C:\$Windows.~BT"
@echo --------------------------------
@echo All done
@echo --------------------------------
PAUSE NULL
We have created the batch file for you, and uploaded it to your own server. You can download it wiht a click on the following link: delete-windows-ws-bt-folders.zip
What about $SysReset then?
The folder $SysReset is a hidden folder at the root of drive c: that is created when a reset or refresh operation fails.
When you open the folder you will find a logs folder in it that contains an .etl file (PushButtonReset.etl), and logs. The file setuperr.log may highlight why the reset or refresh operation failed to execute.
Additionally, Windows creates an etl named sysreset_exe_BootUX.etl in c:\recovery\logs.
The information may be useful when it comes to the system's refresh or reset functionality. If you don't require the information anymore, you may delete the folder as it is not required for system operation.
You can delete the $SysReset folder directly in File Explorer if you have elevated rights. Select it in File Explorer and hit the Delete key on the keyboard. Accept the prompt that requires elevation, and wait for the process to complete. The folder is deleted, but it may show up again in the future when a refresh or reset operation fails.
What about $GetCurrent?
$GetCurrent is also created during the upgrade process. If you open the directory you find a logs directory inside with information on the upgrade process.
The folder does not occupy a lot of disk space, and it is unclear whether it is needed after the upgrade. Information on it is very scarce, and my suggestion would be to keep it if there is a chance that you will roll back to a previous version of Windows.
If you don't, create a backup of the folder first, and delete it afterwards. You can delete it by selecting it and selecting the delete key on the keyboard, or right-clicking it and selecting delete from the context menu.
$Hyper-V.tmp
No information is found online about the folder, but the .tmp part of it is a clear indication that it is used to store temporary files.
It is probably safe to delete, as it will likely be created again when it is required. Either back it up before you delete it, or keep it around as it does not really occupy much disk space wise.
Now You: How do you handle these folders?


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.
motherboard maker MSI has recently released a statement regarding the “unsupported processor” blue screen error for their boards using Intel 600/700 series chipsets & to avoid the KB5029351 Win11 update:

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.
