Does using the SFC /Scannow command never work for you? That was the case for me for a long time. That was until I learned the proper way to use it by combining it with DISM. The System File Checker is a very powerful tool that can fix a ton of problems if you use it right. Today, I'll show you how.

@wjrneo2 Год назад

But only the good techs. Also, you should keep the old release isos around for just this purpose. Aka 1909, 20h1, 22h2. You want to use the iso that matches your installed release version. A command I love to frequently run on a confirmed good running system is the component cleanup command with the reset base switch. Just remember that after it’s been run you can’t uninstall any previously installed updates. So no rollbacks. Windows has a default scheduled task that executes this command, but without the ResetBase switch. Dism.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase

@@MacGuffin1 for me I can say that I had this kind of "magic" last year with an Windows 10 21H2, BUT around 2 month later (after daily usage with ~10hours a day) same Problem was there again (System-restarts out of nowhere). After that nothing (SFC / DISM / inplace-upgrade / driver clean and update / etc.) helped and I needed to reinstall the system. Then all worked fine for arount 4-5 weeks and everything began again. Since it is a custom install Image (on around 100 working systems) it have to be an hardware issue and I replaced the system. All working finde now for around 5 months. Checking the intel NUC (RAM, SSD, add-In card, turn off multithreading and/or turbo boost and of course dust clean, paste replacement) it have to be an defective motherboard. in short that "magics" happen some times BUT they might point to a bigger problem in future.

Microsoft did do some things right.

Excellent and very well explained, very helpful, I am already making a notepad to put all the commands in a folder on the network so that I have them at hand.

I haven't seen any normal videos that explain how to clone to a new desktop with different hardware and an NVMe disk."

@ApolloTheDerg Год назад

I turned the restore health and sfc into a bat file, it’s been super handy, all I do is run it as administrator and it’s part of my quarterly computer maintenance for a small company, kept the same install of windows on these systems for years with minimal headaches this way, often catches small issues early and quickly sorts them out.

@TheEvolvingAudioNut Год назад

Excellent video. I've been using windows since the beginning when it was essentially only a crude graphic overlay on top of DOS. Having gone through Win 95 and 98 etc. I was at a point where I created a clone of a fresh install and would revert to that every year or so as the computer became less responsive over time. So yeah, I became a sledgehammer guy. 😁 Old habits are hard to break. I built my current main rig a couple years ago and was considering breaking out the hammer. I'll put that on hold while I await your videos that further explore this topic. After running the "RestoreHealth" on my cache files, SFC found several files/directories "is owned twice or has its security set twice". It also found one DLL file with a hash mismatch and replace the bad file with the new version from cache. An idea for this series (though I'm guessing you already have it on the list) is to talk about the various utility programs out there that profess to be the "be all / end all", "must have" program to keep your computer at tipity top condition.

Solid walkthrough for DISM repairs, but for anyone that needs youtube videos to teach them it's honestly easier with the modern windows to use the media creation tool and do an in-place upgrade of windows (Select Upgrade Now -> Keep my programs and files) instead of saving the ISO. In my experience it repairs everything that DISM/SFC will ever fix, plus uses an offline Defender to scan and remove any malicious changes to the OS.

@MDFGamingVideo Год назад

It's a balancing act, based largely on knowledge capture of known -vs- new issues/fixes. Turn-around time determines the best approach. * IF * you * KNOW * you can use SFC / DISM / other tools to fix or restore a known issue, and you know that is the ONLY issue, go for it. However, there is another side of the scale to consider... In the enterprise when it takes you 1 hour to backup, re-image, and restore a user's desktop, it may be FAR more time effective to do that. You could spend HOURS troubleshooting and repairing multiple issues, across multiple service calls, all while impacting end user productivity. This is why documentation and knowledge sharing/building is critical to service and support success.

@CyberCPU Год назад

Well, that's just it. It comes down to experience. Historically it's the big box store techs that don't have a lot of experience that tend to wipe systems more often. The argument can be made that this happens more in a corporate environment because the systems don't have as much personal data on them. However, when you're working with consumers saving the OS is a lot more important. Yes, it takes less time to just wipe the operating system and reload it. However you also have to factor in the three on-site trips getting Grandma's scanner to work the way it used to because she can't get used to it and putting the links to her bank and Amazon back on the desktop because you can't figure out how to use the search bar in a browser. 🤣😂 I charge a flat rate in my shop so the customer pays the same whether it takes me an hour or 5 hours. Because I've been doing this for over 20 years I have the experience to be able to still make money with a flat rate. For every computer that takes me 5 hours to fix I have 10 others that I fixed in a half hour and it's all the same flat fee.

I deal mostly with small businesses and most of these users have a ton of customizations and special tools that can take forever to get working on a fresh install. Some examples: An rdp connection to their time clock/HR provider, a VPN connection to their video security provider, A connection to their POS system, QuickBooks, Industry specific software etc. On top of that,the problem often came from something the user recently installed (or updated) and the first thing they will do when I leave is to reinstall that thing. Better to get to the bottom of the problem if possible.

I'm not a tech but I run tons of programs and software and need to fix things within Windows from time to time. I personally would rather just wipe a broken OS rather than chase down specific files or issues because most times its just faster for me.

@nikolatesla169 11 месяцев назад

That's right I'll do the same if it's my computer, but when it's a client's computer and they have a lot of software that I'm going to reinstall and download if I don't have the installers, maybe they lose the activation Keys... They don't want to lose some specific configurations etc etc then I would rather do this fix...

@ShadeAssault Год назад

Well. This makes so much sense. I always hate the forums that do just what you said. They never mention DISM, or if they do, they don't mention SFC. I've known about both tools forever but didn't know exactly what they did and that they compliment each other. Thanks for throwing some more knowledge into my brain toolbox.

@TheEvolvingAudioNut Год назад

An idea that dovetails nicely with the topic of fixing a broken windows install is troubleshooting hardware issues. That particular rabbit hole runs deep. An example from my recent experience... Over the past week or so my gaming rig started doing some weird things such as programs suddenly crashing or doing things other than the command I had just given it. Other times it would wink out and do a hard reboot. Running Memtest86 found bad memory. I had all four slots filled with 8GB DIMMS. I checked each one individually and Memtest86 found issues with every one. I was thinking that it would be unlikely in the extreme to have four DIMM fail at once. I was thinking perhaps the mem controller on the MB took a dump. As I had some laying around, I took some spare mem and installed it. No failures were found. Yesterday I bought a pack of mem (2x16GB rather than 4x8GB). My thought is perhaps having tightly packed DIMMS on a hard running gaming rig is not the best thing. So far so good.

@SpaceCadet4Jesus Год назад

All 4 slots of memory being full has no bearing on the computer operation except if the memory is blocked from air flow, which the memory will accept until it ages. If I had all 4 memory boards showing errors, remove all but one, jot down the faulty addresses of each for comparison, test each memory in a different slot and finally test in another computer if available. Seems like you did a good job and solved your issue. Stranger things have happened.

@ScoutReaper-zn1rz 4 месяца назад

Actually, if you were using all 4 slots and had XMP enabled you might have had a problem because of that. There are cases where the memory controller can't run all 4 slots at the XMP rating as the XMP is technically an overclock and can cause odd behavior/crashes. You did the right thing by resorting to only using 2 slots for RAM.

@SilentPlain Год назад

I'd first do a S.M.A.R.T.'s parameters check to rule out any HDD/SSD failure, then go on with the commands. In some cases, hardware failures can be a potential problem that can be easily spotted with any proper software designed for it (there are a lot of free options out there), thus saving time figuring out what might be wrong and how to fix it (it takes no more than a few seconds to run a diagnose). Sometimes, BSODs are simply caused by corrupted system files that are stored in bad sectors... Just my "2 cents".

@SpaceCadet4Jesus Год назад

Hey...what are you doing here?? 🤨 You're too smart giving away your best practice advice. 😄 (I wrote a similar comment in this video). So many repair shops run to software fixes when it's smarter to always check hardware (and faster too).

@David_Ladd Год назад

Great video as always. There is probably an extra step I would add to this process. chkdsk C: /F /scan Then I would do the DISM line Then finally the SFC line A lot of the issues I have found is also with corruption in the file system which probably should be repaired first before trying to repair the corrupted files as they might get corrupted again.

@SpaceCadet4Jesus Год назад

I'd change the order a bit, ALWAYS check hardware first ! No amount of software will fix bad hardware and you shouldn't let software do a damn thing until you've analyzed the situation. Check the drive condition, sector response test, Smart data, etc.. Replace it if broke or breaking. Only then.... R/click the drive for a diskscan (no /F) [the computer can seriously destroy good files if it encounters an unknown situation.) I want to know the state of the file system before I decide what needs to be done. When drive is replaced, run SFC /scannow. If it fixes corrupt data, then good, you're done. If it can't fix, reboot and try SFC again. If still messed up, then run DISM. Other intervening steps are missing cause I'm single finger typing this out on a 8" tablet.

@CyberCPU Год назад

That's a great point. However, I would use chkdsk /s c: But your way I'm sure works too.

@David_Ladd Год назад

@@CyberCPU very true. Though normally chkdsk wants you to reboot anyway when dealing with drive C: so at least a good point to grab a coffee or a soda pop while you wait :D Besides, each tech has their way of doing things. Normally what works best for them as long as the customer is best served.

@David_Ladd Год назад

@@SpaceCadet4Jesus , True, but here is also a good thing to keep in mind. One of the things I use to do back when I was full time service tech was as soon as system came in was check to see if the boot drive was at least accessible. If so then use Symantec Ghost or equivalent HDD backup software and image the drive so at least the original state can be preserved. If the drive had important data on it and they were willing pay for professional data recovery would send the drive off. If the customer couldn't afford data recovery and they were willing to risk it then would use SpinRight to attempt to repair the drive. Sadly a lot of people aren't willing to spend a lot of labor time trying to fix problems and would rather take shortest route to getting the system back up and running. So normally meant if the drive was still good they would opt for the choice of wipe the drive and do a full clean install of the OS they were using.

@SpaceCadet4Jesus Год назад

@@David_Ladd Like you, I still image all/most of the drives I work on but I ask the customer if I can save it. After the repair, I reimage and save it in an encrypted NAS. It has saved the day way too many times for future problems. I have somewhere between 75TB and 100TB of storage space, of course not all allocated to clients. As for Spinright, somewhere in old pile of diskettes I think I have Steve's original disk. That takes me back to when Steve, myself and others not remembered used to chat over FidoNet. Ever heard of Mace Utilities? It was way better than Spinright or Norton tools. Talked with Paul Mace on the phone trying to get working with him to promote his product more. Those were the days when the information you needed was inside the thick Computer Shopper catalogs. Old times. 😄

@Enjoymentboy 11 месяцев назад

Just wanted to give you a HUGE thanks for this video. I have an older (2009) HP laptop that has tools and utilities I can't get any longer so I cannot afford to format and reinstall. It became essentially unusable as even at idle it would be running 99% CPU and 8Gb RAM at 60°C+ temps even though it was literlaly doing nothing. SFC never helped at all. No amount of looking into this gave me the answers, although I suspect I wasn't searching using correct terminology to narrow it down. I was just about to give up and accept defeat when I found this. Ran through it all last night and I am happy to report I am currently typing this out on that very laptop with 5 tabs open AND a video being recoded in the background.

"Nuke and pave" is quite common depending on the corporate environment, unfortunately. In my org, the (few thousand) PCs we still have that are fat client that can't be on VDI, if a problem is going to take longer than say, 45 minutes to an hour to fix, and it doesn't have any sort of one-off rare specialty software that someone, somewhere managed to lose a license key to, just PXE boot it and fresh install the corporate image and move on. Me personally, I LOVE puzzles and troubleshooting, but I work on the server side of things, not end-user PCs, so that works out well for me.

@CyberCPU Год назад

Yes, it's common in corporate environments, and big box stores.

@SpaceCadet4Jesus Год назад

@Terra Prime I understand the corporate mentality of "Nuke and Pave" as most corporate PCs are not filled with various software from who knows where. Having a few corporate images and a few new unused PCs is the way to go, especially when all client data is server side. I wish my life was that easy.

@opulentnotes Год назад

Thanks for sharing these cool commands! I've actually been using DISM commands to help fix corrupted files on a customer's PC majority of the time, and usually stop at /restorehealth. I had no idea you could run sfc /scannow afterwards -- I always thought it just was not doing a darn thing so I omitted it out of the process. Definitely will try this process next time 🙂 There was one instance where DISM was loading in CMD and it would get stuck at 64% and not move for several mins to a couple hours (even tried rerunning the command), why is that?

@glebglub Год назад

my guess is the anti-virus going mental scanning every single file that is being manipulated on a spinning-platter HDD, alongside slow internet speeds as dism is updating files through windows update (which would thence increase how much work the antivirus is doing as it's effectively scanning the same file 3 or more times and communicating with the cloud server about it, depending on your settings). could also be the storage device is way too full so it can't move files around as efficiently (typically ~15% free space is recommened iirc). maybe only 1 stick of RAM operating at minimal frequency, overheating on the CPU as the cooler shifted in transport, especially if it's a heckin' chonker like my NH-D15 (though for these I'd recommend unmounting the cooler as it can damage your motherboard/cpu in transit, at least without that expandable foam stuff SI's use for pre-builts to keep it in place). but I'm no expert, so there may be some other things going on too I'm not aware of, these are just my thoughts without knowing more of the system(s) you were working on

@opulentnotes Год назад

@@glebglub Thanks dude, this is pretty helpful info as I did not know the anti-virus plays a role in this. I work for a big corporate company, and our company PCs are basically all laptops that have 10th gen and higher CPUs and NVMe M.2 SSDs. Your guess is as good as mine, our machines have McAfee and its tied to group policies to make sure the device is in compliance. The internet connection could be a possibility -- as since covid we use remote connection to troubleshoot machines and requires us to connect to a VPN which tunnels to our company server. We do this in order to elevate admin privs on the user's machine (we need to do this to even access CMD as Admin)

@glebglub Год назад

you can force windows 11 to install, though personally I stick to the LTSC branch for every windows install now and windows 11 LTSC isnt out until next year. as for linux, you can always dual-boot until get to grips with it; I'd recommend VanillaOS as, even though it's pretty recently out, it's pretty secure and it allows you to install arch/debian/fedora/flatpack packages through containers, so you won't need to distro-hop if you find a program that's ONLY on one flavour of linux, or one's buggy/not updated/etc. (though it has a much larger disk footprint due to the ABroot thing they have going on, and how many containers you use)
