Where can I download a newer version of uexfat.dll for Windows 7?

MothballsWallet

My PC runs Windows 7 Home Premium (64-bit) Edition with SP1 and all available updates installed.

I recently bought a Seagate Expansion 4TB USB3 external hard drive to replace my existing 2TB model which is getting on a bit (I've had it for around 10 years), which is working fine but I'd like to run CHKDSK on it after a brownout on Sunday afternoon (I've already CHKDSK'd both the internal and external 2TB drives and they came back clean).

When I run CHKDSK on the 4TB, which is formatted as exFAT, CHKDSK reported a large number of corrupted data errors, which I thought was weird, so I cancelled the operation and searched online, where I found a thread that told me that the Windows 7 CHKDSK had a bug that caused it to falsely report corrupted data on NTFS-formatted drives larger than 2TB, which Microsoft fixed with an update.

However, the original thread poster went with the premise that a similar bug existed for exFAT drives larger than 2TB and tried using a Windows 10 machine to check their disk, and that worked. They also included a link to the Microsoft Support page here.

So, I've followed that link and I should be able to download a hotfix to fix this problem with version 6.1.7600.22320 of the uexfat.dll file - when I go to the Windows Update Catalog using the link in that Support article, it only shows Windows 8 and Windows Server 2012 versions for download:



I've tried to contact Microsoft Support, but the chat function isn't working just now.

My system has version 6.1.7600.16385 of the uexfat.dll file in both the System32 and SysWOW64 folders (85KB and 66.5 KB in size respectively).

I was wondering if anyone has an idea where I can download the 6.1.7600.22320 versions of these files please? I've tried searching the Windows Update Catalog for hotfixes in general and can't find anything helpful - several of the updates listed no longer have a working Knowledge Base article to explain what the update is for.

The big problem you have is that W7 is no longer supported so M$ will not be interested in helping.  The file does not seem to be available for download in that version from any of the .dll download sites, the version you already have is readily available.  The big question must be why have you not updated to W10 ?

It's on my "to do" list, along with buying an SSD to install as the boot drive and a RAM upgrade for the system as well, although Windows 7 works fine for us.

Also, unless I use a grey market key reseller, it costs £119 to buy the Windows 10 downloadable installer from Microsoft, so I'd like to do all 3 upgrades together.

There are already unpatched vulnerabilities in the wild for Windows 7, please expedite replacing it before you end up part of a botnet.

Would the op know if he is already part of a bot network?

Unlikely.

I wouldn't connect any Windows 7 PC to the internet these days, even will full anti-virus and anti-malware.

Unfortunately, that offer's been dead for 6 years: https://www.zdnet.com/article/microsoft-quietly-announces-end-of-last-free-windows-10-upgrades/

Thank you - that's the hotfix I need, and it's fixed the issue for me

Read the date on the article I first linked to.  Jan 14 2022.

And the offer is not "dead", it never was dead.  What you've linked to is the official line.  Officially it is dead.  But in reality it isn't.
