How to enable USB Flash Drive Write Protection in Windows

System administrators may want to limit the use of external USB flash drives by making them read only. This can actually be useful in several situations like preventing users from copying local data to the external device, or preventing malicious software from spreading on a computer network using those flash drives (from an infected computer to the Flash drive to other computer systems it is connected to).
The Windows operating system has a Registry setting that can be used to enable USB write protection on a computer system so that data can be read from devices connected via USB but not written to. It is like a switch that can be enabled to make use of the write protection, or disable it to allow write processes which is the default setting.
Users who experience problems writing to USB devices might want to take a look at this setting as well if they have the proper rights to do so to see if it is the cause for the issue that they are experiencing.
Enable USB Flash Drive Write Protection in Windows
Start by opening the run dialog box with the keyboard shortcut Windows-R. Type regedit, and hit enter on the keyboard. This should open the Windows Registry editor.
Navigate to the following Registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
Look at the sub-keys and see if a key named StorageDevicePolicies is listed. If it is skip this paragraph and read the next. If it is not create the key by right-clicking Control and selecting New > Key
See if there is an entry named WriteProtect. It can be created easily if it is not present by right-clicking in the right window and selecting New > Dword (32-bit) Value from the menu. The following values are allowed for this entry:
- 0 - This will allow write processes on USB Flash Drives
- 1 - This will block write processes on USB Flash Drives.
An alternative would be to delete the Registry key WriteProtect completely to enable both read and write processes. A restart or log off is required before the changes take effect.
Group Policy alternative
If you have access to the Group Policy in your version of Windows, it is available in all professional, ultimate and Enterprise editions, then you can make the changes here as well.
- Use Windows-R again to open the run box.
- Type gpedit.msc and hit enter. The Group Policy Editor should come up.
- If the editor opens up, navigate to the following folder: Local Computer Policy > Computer Configuration > Administrative Templates > System > Removable Storage Access.
- Here you find removable disks and removable storage which you can both deny write access, execute access and read access.
- To do so double-click the entry and select Enable.
Tip: You find options to disable execute or read access as well there.
Verdict
Disabling removable disk write access is easy to set up on Windows. You can do so using the Registry, or Group Policy.


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.
