Microsoft: Windows 10 Bitlocker is slower, but also better
If you encrypt the hard drive of a computer running Windows 7, and then on the same computer running Windows 10, you will notice that the encryption process is faster on Windows 7.
Bitlocker is a built-in disk encryption program that you can use to encrypt data so that it cannot be accessed by third-parties. If you don't encrypt your hard drive, anyone can access the data on it even if the PC is not on.
With Bitlocker and other encryption software, this is prevented.
Side note: Bitlocker may not be as secure as it could be on Windows 10. Windows 10 seems to decrypt data on the drive during feature upgrade processes.
Reasons why Bitlocker is slower on Windows 10
In Why Bitlocker takes longer to complete the encryption in Windows 10 as compared to Windows 7, Microsoft Support Escalation Engineer Ritesh Sinha describes why Bitlocker encryption is slower on Windows 10.
The answer is a bit technical, but it boils down to improvements made to the encryption process itself, and changes that went into Bitlocker that make it somewhat of a different product than the version for Windows 7.
The big change to the encryption process itself is a new conversion mechanism that Microsoft calls Encrypt-On-Write. It ensures that all writes to disk are encrypted as soon as Bitlocker is enabled on the operating system. This works for internal drives only at the moment. Microsoft does not use the new conversion mechanism for removable drives for backwards compatibility reasons.
This change is important for data security, as you could not place important data on a drive on older versions of Windows before the Bitlocker conversion process reached 100% due to the fact that the data may not have been encrypted immediately.
The second reason for conversions to take longer on Windows 10 is that Microsoft configured the Bitlocker process to run less aggressively. This improves system performance while the encryption process is ongoing and results in a longer conversion process.
Microsoft notes that other improvements went into Bitlocker on Windows 10. These have no impact on the encryption process but may be beneficial in certain situations.
This includes support for encrypted hard drives, HDD and SSD hybrid disks, new means of administrating Bitlocker, new FIPS-compliance, or Bitlocker Network Unlock.
Closing Words
I have not seen any report on how longer the Bitlocker encryption process takes on Windows 10 compared to Windows 7.
This is obviously not that much of a problem if this is a one-time operation. So, home users may notice the extra time it takes but it is a one-time operation.
The extra time it takes to encrypt drives using Bitlocker on Windows 10 may be an issue however for system administrators who run the operation regularly on company devices.
Now You: Better data security but slower encryption, a good trade off? What's your opinion on this?
Possibly the first useful article from Shaun?
Many previous articles have described how to install an earlier version of Windows, right back to Windows 7, using a download from the MS website.
What is perhaps significant here is that there is seemingly no barrier to installing Windows 10 on a brand new computer shipped with Windows 11: no block set by MS if one could be set.
The first screenshot does, though, show an image that include a reference to the need for a Windows 10 licence: maybe not reflecting the current situation, or maybe the licence is deemed the same?
I have tried win10/11 .. I like the new win11 UI, BUT everything’s in the wrong spot. It should be like windows 7, with the UI of 11. You know how a man can have the most beautiful woman ever, and mess it all up, and wake up and she’s GONE!? Well this very thing MicroSoft has done to windows.
Windows 7, WOW she’s a sexy doll. And MicroSoft turns right around and mess’s everything up.
I know a lot of people online, and they are leaving win10/11 and going back to 7. They say
” I don’t care if Microsoft don’t support windows 7 any more, I’m going to use it”
Am I right that a clean W10 install would wipe the partition on which it is installed?
That would remove all ‘bloatware’ but also any possibly useful device manufacturer’s utilities, so anything wanted would have to be backed up in some way before going ahead?
Best useful article of 2023 just the first day. Thanks @Shaun, keep going on!
It would also probably wipe your OEM partitions as well FYI. In case you decided you wanted to actually go back to Windows 11. Although you could also make a Windows 11 install with the Microsoft creator tool for Win 11. I like both Win 10 & 11 I have no issues with either OS. On a new PC especially some CPU’s with the Intel P& E cores Windows 11 works better with those new CPU’s.
Happy new year. But why to go on windows 11 ? Wait for that, we have almost 3 years to the retirement of win 10 on 2025. Wait and see. If microsoft continues to destroy their os, we have to stay on older versions.
Note: “Only the Professional versions of Windows desktop operating systems include downgrade rights.”
It not quite so simple.
Before attempting a downgrade, I would recommend reading more about “downgrade” rights. Not all OEM licenses from manufacturers will allow the process.
In theory, though, the embedded license is interchangeable. Back to Windows 10 with an ISO, forward to Windows 11 with an ISO at some future date. Like downgrading is going to solve all of one’s problems . . . .
Is Windows 11 THAT bad? Not having issues here; it would be a pointless exercise unless one had an essential program that didn’t run on Windows 11, which would be next to impossible.
A number of factors could be involved that wouldn’t result in a Blue Screen Boot.
Don’t know–drivers, BIOS?. Rather spend time on learning the new system and dealing with difficulties as as they present themselves.
Wouldn’t go there; it’s like upgrading to Windows 11 on a computer that isn’t supported. Possible, but why would one do it?

Move forward.
Thanks for this article.
As the method in this article would wipe/remove user data on the PC, could we also have an article to restore a Windows PC back to Windows 10 while RETAINING data after a user has accidentally updated to Window 11? Forgive me if that has already been posted or I am misunderstanding this.
Also, I suppose it may be useful to make it even clearer that the article is about totally starting over and losing any data on the PC. Yes, it does say it in the article, but… just to be safe in case someone is reading it fast.
>As the method in this article would wipe/remove user data on the PC, could we also have an article to restore a Windows PC back to Windows 10 while RETAINING data after a user has accidentally updated to Window 11?
If a user inadvertently accepts a MS offer to upgrade their Windows version from 10 to 11, or accepts an offer and then regrets having done so, I think that we can assume that *only* Windows itself will be been updated: the disk will not have been wiped, and any user, OEM or other data or partition will be completely unchanged.
However, if a user plans to use the above method to replace Windows 11 by Windows 10, they would be very well advised, in accordance with normal advice, to image their complete drive before before starting, to enable anything that might be required later to be reinstalled..
One does not desire Windows 11. It’s becoming obvious that Microsoft is making an incredibly vain effort to make Windows 11 seem successful. Even while Windows 10 is still fully supported, they stopped licensing OEMs with the ability to downgrade to Windows 10 in October of last year. Consequently, Windows 11 is installed on all recently purchased machines. Because we remove the Windows 11 image and replace it with our Windows 10 image, this is not a major issue. Microsoft place their horrible Windows 11 where the sun doesn’t shine.
This site has become a mass advertisement of windows 11! Daily promotional articles for this OS! Why don’t you post an article about AtlasOS?! Oh yeah, you’re going to delete my opinion again – you’re censoring people’s free expression!
Whether one likes Windows 10 or Windows 11, the point not-to-be-missed here is that Microsoft is working really hard to make Windows a platform for monetized SaaS. Microsoft accounts (preferably with upgraded OneDrive storage), Microsoft 365, etc. etc.
I would absolutely go back to the days of paying Microsoft $80-100, or even $129.99 if they would offer an ad-free, telemetry-free Windows Pro OS that also doesn’t strip the Pro features in order to treat me like a consumer user. And since they will not? I feel perfectly justified in using the Windows Registry, Local Policies, and firewall-PiHole blocking techniques, whatever it takes, to block, strip, or blackhole the ads from their operating system. I already have half a dozen Windows 11 Pro licenses with matching Office 2021 Professional Plus licenses that indicate I’m willing to pay them. I just want them to leave me in peace.
Foolish, you’re basically saying “I am going to keep giving you money despite the sub-par user experience and product you provide, BUT it would be nice if you improved your product anyway”.
That doesn’t work in the real world – Microsoft is acting like this because they simply don’t care about the OS space, they have decided to milk the end users as much as possible.
Use Microsoft products only as much as you are required to, by your workplace, or your clients. Run windows 10/11 in a VM environment and find alternatives where possible. Microsoft’s behaviour in the past how many years has signaled that they are only gonna get worse.
Windows’ “System Image” backup feature has been broken for almost a decade. The only backup software I’ve used that has been able to integrate properly with windows 10 has been Macrium (native windows volume shadow copies, incrementals, easy recovery environment creation, encryption, etc).
Comments are messed up, again. Ghacks isn’t what it used to be…
I heard microsoft is working on windows 12 – should i wait for that? When would THAT be released? I have 3!! incompatible win 10 desktops.
I wonder EXACTLY how many laptops & desktops do NOT meet win 11 requirements!
In the hundreds of millions? Close to a billion?! Imagine how many would need to be recycled(or thrown away in countries not recycling), not necessarily using green power to do it. & to make new ones. My head is spinning.
I sure hope at least win 11 is a lot faster than the sooo slow win 10 file manager & picture viewer.
Windows XP was sooooo fast in those areas.
Microsoft should have come out with some sort of inexpensive device or software that would EASILY MAKE incompatible win 10 pc’s compatible.
Is it only for me or are the commands for configuring VB for macOS all “cut up”? Like it’s literally a screenshot with half the command? I’ve tried multiple browsers what should I do lmao
Thx in advance
Same here! I wasn’t sure if the author of the article is trolling or not
