How to uninstall Windows 10 Technical Preview


  1. This is amazing news, my cocern is if im going to have all my documents and progams in place after unistalling the update? Unlike the average person who would back up there system i just went all out. Any advice

  2. I’ve install W10 TP on clean desktop PC no other systems. And now I can not use boot from dvd and install something else. How can I remove W10 TP?

  3. it won’t revert back to anything except back to before you installed updates since installing the tec preview it’s still tec preview

  4. I went to remove the Tech Preview from Windows updates and the update was not there , so I went into recovery console via ctrl shutdown and I selected “Uninstall Tech Preview” I got an error that it couldn’t find at update … Guess a full reload is in order

  5. I had the same questions, I would like to remove it entirely and put Windows 8.1 back. I am not sure if it can be done without a full reload. Any ideas? I am running a Dell.

  6. ^^ Seems like you need to change boot order. Enter into BIOS or UEFI settings, whatever your system have and then give first booting preference to DVD. Then during installation, you can format the drive and remove W10 TP.

  7. I can’t get access to BIOS and change it. Computer was clean and when I set dvd with Windows 10 it starts which means DVD is set as bootable but now don’t work or Windows 10 change something or brake it… any other sugestions???

  8. Thanks for the tip. I installed it in a partition on an old Vista laptop, but the size of the partition proved too small to do much more than look at the OS.
    Therefore I’m going to just install the preview on the whole drive. I hardly ever use the laptop anyway, and losing Vista is no loss.
    If all fails, too, I have an old OEM XP CD 😉

  9. Could you make a tutorial on how to do this? I don’t quite understand how to do it, I can’t bare Windows 10 anymore!

  10. I have one question, By the looks down below, it only uninstalls the actual updates.

    I want too completely uninstall it and go back too my windows 7. Plus, I’m confused on how to do this…

  11. .Brilliant! Installed easily?used an office product key from &&& windows 8.1key sale ***on bing and then it worked fine , perfect torrent ,thx!

  12. I tried to get to the uninstall on my computer, but did not get anything that told me to uninstall preview updates. The person who formatted my hard drive put Windows 8.1 back on and also the Windows 10 TP I just want the TP GONE!!! It had messed up my machine to no end. Can’t tolerate it.

  13. I would like to know the procedure to uninstall Win10TP using the command line within (shown above) Troubleshoot > Advanced Options > Command Line. My Win7Pro system is hung up and the command line seems to be my only option to uninstall Win10TP. My system is hung up and I only see the blue windows of step 2. and step 3. (above) plus the Advanced Options window.

  14. I installed it but like a dummy I did not partition my hard drive, however I do not see this update you are talking about and I have 9 different ones is there a newer version on how to do this?

  15. Please help me ! , I have a Windows 10Technical Preview, before i have original Windows 8.1. I dont have with my notebook product key. and I dont know how unninstall Windows 10TP. Please help me

    My mail:

  16. This is the most ridiculous article I have ever read. Your instructions for removing Windows 10 from a dual boot situation are absolutely wrong!!! How can a Microsoft MVP be putting out this trash?

  17. Actually I don’t like Windows 8.1 that much which I think a lot of users have the same feelings like me. Now I’ve updated my computer to the Windows 10 technical Preview already. I’d like to give a thumb up for this compared to last one. I also tested several programs including free and a paid one Macgo Windows Blu-ray Player. Works fine!

  18. ^^ That’s an expected situation which we haven’t faced yet. There MIGHT be a system corruption occur, or you’ll be remain with Windows 10 even after rollback. But as I said, we’re not sure about this. Users are advised to perform rollback when there is minimum possibility of power cut.

  19. WOW cool!!!! i got my 8.1 back with EVERYTHING back in 5 minutes!!! WOWOWOWOW why cant installation be like thiis???i never knew about rollback lol win10tp wasnt that buggy

  20. It shows me roll back option but give some error… I am also no able to install a fresh copy of windows via usb,.

  21. Hi, I downloaded the Windows 10 Technical Preview *installer* on my tablet, but I can’t install it because it uses a compressed boot image. Unfortunately, “Upgrade to Windows 10 Technical Preview” now appears in my Windows Update constantly, as the “next update to install.” Even if I hide it, it shows up the next time. Is there any way to remove this from Windows Update? (So that it only shows Windows 8.1 updates, rather than the W10TP?)

  22. Hi, please i mistakenly hit the “Windows Rollback button”, how can i get back to the upgraded version without redownloading it (how can i undo the rollback)

  23. And up with blackscreen, old windows 8.1 doesn’t start anymore. glad I have a acronis full backup!

  24. Unfortunately this won’t work if your last version was not windows 8.1 but a previous build of the tech preview. For me, it rolls back to the previous build (which I like and would love to keep) but a few days later, it reinstall the nonfunctioning build. If I could, I would keep the last build around, but having to reinstall and rollback every three days is just too annoying. Keeping 9926 is not really an option either since Youtube, Netflix, Facebook and all office programs stop functioning completely in it.

  25. i have windows 7 ultimate on my laptop than i upgrade windows 10 TP than how i use my earlier version win 7 ultimate and at upgrading did my local disk data delete or crack please reply

  26. I understand that the option to just roll back is a good thing. But in my eyes, i dont want to get this choise everytime i start windows 10. Is there any way to hide that option and restore only if you need to?


  28. Sean, that isn’t necessarily true, it worked for me… i installed windows 10 directly onto my HDD, I didn’t mess around with duel boots or external drives or anything. A recent update made ableton no longer able to work with win 10, so I chose to restore windows, thinking it would just remove the updates from windows 10, however it rolled me all the way back to windows 8.1! relatively seamlessly and fast which is good, I’ll make my way back to windows 10 eventually

  29. I have selected the wrong resolution and now NOTHING will display on Win 10 and I cannot change it to roll back…Any ideas pleeeease

  30. I rolled back to windows 8.1 from windows 10, how can i find the files that were on my windows 10 desktop

  31. One problem. Once you’ve rolled back toWin7, windows update will keep trying to re-install 10. Even if you choose to hide the Technical Preview Update, it will reappear. I have hidden this 6 times and it is listed 6 times when I choose to Show Hidden Updates.

  32. Disable update notifications. since it is an optional update, you can force installing of important updates only.. fixed.

  33. Right i have a problem. Basically the “Rollback” option has been removed from my system after i did a System Refresh to sort out some minor issues. So now i am stuck on Windows 10, it’s as if Windows 8.1 never existed on my computer, I am tempted to attempt a factory reset… but i fear this will remove the OS altogether and ask to reinstall the OS (When i brought my computer from Dell, they never gave me a Windows 8 key or disc, so this creates problems). Any ideas on how i could proceed anyone? Microsoft wasn’t very helpful on the matter to be honest with you.

  34. Installed Windows 10 technical preview last week as an upgrade to Windows 7 home, everything is woking fine other than having to reinstall a couple of programs. My issue is that my PC now takes over 60 minutes to startup, the initial POST run to login is fine but after login I get a blankscreen until everything is loaded, the HDD activity indicator is flashing away during this time.

    Has anyone experienced this and dio they know of any resolution I can try before I unistall Wivdows 10?

    Thanks in advavce


  35. After deinstalli9ng the Win 10 TP, to Win 7, i can’t run any program! what’s going on there? Some of my .dll files don’t exist! Please help!

  36. when i start windows 10 it doesnt have that option anymore,it just gos straight to the sign in thing. what should i do?

  37. Is there a way to UNDO this? I had know idea switching to rollback would literally uninstall windows technical preview (Was having problems running certain software and wanted to see if Windows 10 was the problem). I cant just get a blue screen asking me if I would like to revert back again?

  38. Doing this crashed my computer, sent it into boot loop and now I can’t reinstall windows 8.1! Helpppp

  39. I made the MISTAKE of installing windows 10 on my laptop today. Not only did it take 4 and a half HOURS(when it claimed the install was instant) to install, but I was FORCED to shut my computer down because I did not have another 12 hours to waste for the rest of the process to be completed.

    If you change your mind for any reason, all you have to do is shut your computer down. When you reboot it, Windows 10 will automatically revert back to your previous program, although that process seems to take about half an hour.

    It wasn’t worth it to me. I panicked for a moment, until my computer FINALLY returned to Windows 7. No more fancy upgrades for me. The installation process is RIDICULOUSLY SLOW. Don’t take the chance if you don’t really NEED to.

  40. Go to the control panel, under the colorful windows start up button and choose uninstall under programs. This should bring up a list on the right of your recent updates. This update will be listed as microsoft and should have a number in parentheses that is K90… followed by the rest of the numbers.

    I forgot the actual number, but is starts with K90…. Then highlight it and either right click or click on the upper uninstall feature. This will get rid of the update and you shouldn’t have this problem any longer.

    If you’re not sure which microsoft product it is, go by the date you installed this feature. If your still not sure, look up how to uninstall windows 10 tech and the number will be listed there with the uninstall instructions.

  41. Updated 7sp1 to win 10 technical preview via download. Many issues with 10 but rollback option doesn’t work..I wouldn’t have installed if I know rollback was broken. Should have known better. than to trust MS. And 10 updates have failed. I’m stuck on 9926. Bluetooth headset will no longer connect. Video driver failed and had to reinstall several times. Can’t turn off Web search in search bar but that’s okay, it usually won’t accept ANY

  42. ^^ Mount the Windows 10 ISO to your system. Boot your system using this ISO and start the setup. You must see there “Repair your computer” option. Click it, select Troubleshoot. You’re now arrived at first image 🙂

  43. I have installed Windows 10TP and had that “choose operating system” screen initially….however. I came back to find my computer having restarted and now the screen does not show on boot up. My steam games no longer work and i want to roll back, but can not figure out how. Surely it should be easy…..

  44. I am not given the “Windows Rollback” option on startup. I currently run build 10049. Any suggestions?

  45. Or if, like me, the boot option has disapperared do the following:
    Go to Start Menu ? Settings ? Update & Recovery ? Recovery, and click Get started button under Go back to a previous version of Windows.


  47. I tryed to do this, and i accidentaly clicked windows 10 tp instead of rollback
    And now my laptop is stuck on the start screen and it wont go in desktop, it says please wait for almoast an hour

  48. Help! I can’t delete Windows 10 Tech Preview! It says this: “The files we need to take you back to a previous version of Windows were removed from this PC”. I can’t do Windows Rollback as I get an error which I think was Error Code 0xc000000f. I’m basically stuck on Windows 10 and I want to go back. Please Help!

  49. Hey, I installed windows10 on my WP yesterday and I couldn’t use my SIM card so I decided to restore factory settings, but I can’t do it. My phone still is in windows 10 and it doesn’t show menu or something. I’ve tried to restore it from PC, but I can’t do it too. what to do? pls heeelp :(((

  50. I enjoyed it, but I had trouble properly running Xamarin Android Player so I had to revert back to my old system.

  51. How does one uninstall Windows 10 TP from a Windows 7 system with two hard drives? I installed Windows 10 TP on a 500 GB hard drive. My system drive is a 2 TB.

  57. I just installed W10 today and that option doesn’t exist on my boot screen. Just windows and my macrium reflect which I tried to use but it won’t work either. I thought if it didn’t work or I didn’t like it that I could use my reflect image and restore but it won’t let me 🙁

  58. I got mistake in my pc.. after i go into the Updates and click the “go back to previous version”. My pc now wont boot and keep on restarting. What must i do to my pc to go back in windows *?

  60. i’m old school and i don’t understand most of windows10 everything appears very complicated to me.i think i’m going to stick to my good old fashion windows7

  61. I know he is telling people to totally reformat their hard drives instead of just rolling back this guy is a idiot.

  62. Then you didn’t use it enough…its all bugs and spyware from the NSA when you install this your instantly connected to the cloud….

  70. For some reason, there are so many people here that have never left their house and expect people to know what they are talking about.. I had a comment asking for a tutorial and got abused by some guy for not having the knowledge..

  74. Tried a roll back to windows 7.. the damage thing is crashing and goes to repair windows then fails.. now I’must depressed because I would have to reinstall from an old version of Windows 7 with thousands of updates to download and install and hundreds of gigs of programs,games and hundreds of hours to get back everything..

  75. I installed 10 over 8.1 in an almost new Lenovo C260. Because of slowdown, I used the Rollback option and PC ended up locked in a loop of the Lenovo logo and the message, “PC ran into a problem and needs to restart. just checking for errors and will restart for you” That has been running for a week. There is no response to keyboard functions. Power down and up goes back to the same loop. I think I’m screwed unless there is a miracle worker out there.

  83. “Start the machine and boot into Windows 10 Technical Preview latest build.”

    great instruction.
    Like me saying “If you want to get to my house just come down my street and I’m the last one on the left.”

  84. I installed Windows 10, it made my system very unstable. I attempted to go back to windows 8…and my computer crashed. Did everything by the book. Next time I’m waiting until the new operating system has worked through all the problems. Lesson learned. Thanks Microsoft for NOTHING!

  86. I kept getting a blue screen with an error message “critical process died” and had to wait for the computer to reboot at least once an hour. Thought it would be taken care of but was not. Finally went back to 8.1 by using my original computer instructions since the W 10 instructions didn’t work for me. Much happier now.

  87. How can you downgrade from a clean installation since there no other OS install but the clean version ? You can’t downgrade if you don’t have another OS available, meaning no recovery partition or OS software

  88. Kapil, you don’t seem to have answered any questions for two months. Are you just fed up with all the questions about Windows (rubbish) 10?
    I would love to uninstall it too but it won’t let me.
    None of my ports are recognised. My Bluetooth has disappeared. I can’t download from my camera or phone.

  89. I haven’t installed the “Get Windows 10” OS yet, how do I get rid of it completely? I’ve heard horror stories about all my favorite games and programs no longer working, or the need to hack programs to install things, ugh, its sounds horrible! Windows 8 FOREVER!

  90. Mine doesn’t allow me to do anything, it stays in a running mode but I can’t move the mouse nor make any changes.

  91. Always back up first, before an upgrade. My husband upgraded my PC without warning me. I did not have the chance to back mine up first.

  92. so basically I’m screwed on rolling back to my previous version of xp since it’s been over a month since I installed windows 10 and the windows.old file is deleted? Windows 10 has slowed my pc down an unbelievable amount. I’ve cleaned everything and run avast daily and I really just want my xp system back. I have no back up disks for xp, it came on the pc that was given to me.

  93. Windows 10 is absolute horseshit! I cannot remove it from my system and it updated itself on my computer. I DO NOT WANT THIS DAMN OS GIVE ME BACK MY WINDOWS & or at least let me install Ubuntu cause this OS is shit.

  94. HP Pavilion laptop came with Windows 10 and for some reason, I CAN’T GET RID OF THIS DOG. Please HELP. Computer will not even “allow” itself to be erased. What kind of fascist, cancerous program is Windows 10, anyway?

  95. You will not be able to change your OS. Your laptop came with an OEM Windows 10 key. You will not be able to downgrade. The only way is, you will have to buy a retail key for Windows 7 or Windows 8.1 and fresh install that OS and use that key.

  96. I purchased a new laptop with windows 10 and was wondering if it’s possible to uninstall win 10 and install a fresh windows 8

  97. For such an intelligent dude like you, people should be knocking down your door to solve their problems .
