3 Dos commands that you need to know!

DOS Rocks!

Direcotry of System or Disk Operating System (DOS) is one way the technology is good at fixing certian issues. I am going to talk about some that you might or may not know about.  Each command is good for those who are connected to through a network or network group.   If these system are on the same workgroup and are on the shared through the network this will help you in solving those really problems.   You’ll love these as much as I use them because they are really good at keeping you looking like a genius.

FSUTIL (Microsoft learn)

C:\fsutil volume diskfree \\(Shared drive)  

You’ll need to add the \\ as the shared drive or shared system that you want to know how much space is left on it if you need to know at a quick glance will this file or program fit on this drive.   It’s very useful for those times that you may need to keep track of the space.

QUERY (Microsoft Learn)

query session /server:computername

query users /server:computername

one of thse can be used to determine if there are users who might be causing problems by being logged in but aren’t actually doing anything on the system.   These users could be from a previous shift or might of been logged in for a while without any activity.  So this helps to know if a program or access is causing another user from not being able to do their job one way or another.  This is great tool for corporations where more than one users could be using the system at one time or another.

LOGOFF or SHUTDOWN

logoff [<sessionname> | <sessionID>] [/server:<servername>] [/v] (Microsoft Learn)

shutdown /l /r /m:(Computername)  (Microsoft Learn)

Each one of these commands does about the same thing but one reboots the system also because you never know when the remote system might need to be rebooted also after forcing the user to logoff.   So you can decide which one you might need to user remotely for a system.   You can even add in comments or tell the reason why the system rebooted with the shutdown command by adding  /d [p : u](Planned or Unplanned with a number 1-256) .   I will remind you to be cautious as to what you put down as the reason and you can even specifiy how long to wait before the system reboots by adding /t 0-256 MINUTES.   Each one of these command can be helpful for you when you are trying to solve some minor major issues with a system not working properly.

DOS is Powerful

Wheather you want to believe it or not, DOS can be a very useful tool for those who might need to fix issues with the system like windows and other issues that you might need help to fix certain issues that might arise on the system.   You can find some great useful tools at the DOS prompt but you have to be willing to learn it even more than most because it is so much like Linux.   I definately say old and new techs should know how to do this and use the dos prompt when you need to fix issues.  Do you have a favorite command prompt that you use?   Why not leave a comment and tell people about the command that you think is the most useful command?   I’d like to hear it and learn even more about the power of using the DOS prompt.

How The Last of Us – will win the silicon lottery!

Last Of Us Pt 1
My Screen of the Game

Understanding the Silicon Lottery

Whether you like it or not, that CPU or GPU you bought might not last the entire time you have it.   After all, You could have a slighly below average CPU from what others who have the same CPU are experiences.   There is a great Youtube Video on this that you should go check out.   Let me be clear that I think most of the people who are having issues with games such as this are those who have faulty CPU’s or GPU’s.   So a break down of what I have found out, most users who are using a K series Intel isn’t have much issues with the game.   Why’s that well the video tells you what I have always suspected those cpu’s are higher end and probably aren’t likely to fail as much due to the high demand of quality they are wanting out of the series.  Even in th discussions there are several post about who can run this game without issues.   I will admit I had to turn on V-Sync, DSS, and make a limit of 9 FPS to get my GPU not to be used at 100%.  This is something you should do too.   I also did notice some cutsceens (Cineramics) For the game did drop me back into Windows 10.   So I do not like that idea but it did   Even though people will probably blame the game for their GPU’s dying, but in truthfullness you should already be limiting just how much the system uses your GPU.

Gameplay for my Systems

I found this to be very rough to start up with since there was at least an hour that the system was using 100% both CPU and GPU.   It doesn’t help that you have to build the shaders and I honestly would like to know how much space those are taking up in bouth my Steam Deck and PC but I couldn’t find any information, I have found people asking the same question but I have yet to find a way to see just how much shaders are being stored on my systems.  That would be something I would like to know at a glance on my Steam deck.   I have 42gb on my 256gb NVME drive on my steam deck that just say other.  So why can’t Steam fix this for us.

System Specs:

  • I9-10859k on a Asus Prime Z590-P Motherboard  (240 Watercooled Rad)
  • 3050 Geoforce RTX GPU
  • 32 gb DDR4 4,300 ghz ram
  • NVME Hard drive

As you can see this isn’t beginner PC, I built this for my enoyment and thus I know a thing a two about keeping the system cool.   It was constantly getting hot while building the Shaders which took an Hour at the least and I don’t know why they would need to build the shaders in the first place.

The Game

Other than the problems I had, I really didn’t have to much else problems on my computer so far.  I’ve been playing the game on and off for the past few days and I’ve not seen anything else to cause me trouble.   Is that because I won the silicon lottery, that would be a good guess and I’ll probably say yes.  I’m not sure why others are having more issues, but I would be willing to bet it is because they are letting the game take over their Frame rates and cause more issues than they need to.

SteamDeck Play

I even tried it on my SteamDeck and it only could do 20 or 30 FPS on it and it was very intuitive playing it because there was always those times you just couldn’t keep up with the game play due to it stuttering and don’t remind me of the hour long shaders building for it.  Again that needs to be fixed, we shouldn’t have to wait an hour just to play the game, which I did just to not have any stuttering in the beginning game.   I still don’t get the idea of why this is necessary, I thought our systems could build shaders as we go or maybe build the shaders for the next part of the game and so on.   I am hopeful that they at least make the game a little more playable on the Steam Deck because it was something I would like to do more often.   I play Spiderman on it without much issue but The Last of Us just seams to be a little more harder for me to play on the Steam Deck.

Top 3 Useful Windows Commands for Desktop Support technicians

Paul

Windows 10 21H1

The Command Line

Most user don’t understand just how powerful the command line can be.  In tech, and also in my job I have to diagnose and troubleshoot several different types of issues.   I’m going to show you my top 3 commands that I use in Windows and why.  Not everything is straight forward but It will help  you understand why.   We’ll talk about these and why they are so useful and powerful.  Use these as you see feet but you will need to run the command line as Admin.   How to do that is simple, for most.

WINDOWS Key + S and type cmd but don’t hit enter.

Click on Run As administrator

Once you do that you will see the usual Command line windows appear.   We won’t go into detail about that but if you want to learn more about it.  There are several YouTube videos about it.  I’m not going to talk about those because other’s have but I will talk about the commands I use most often in my work.

Deployment Image Servicing and Management (DISM)

For any businesses that use their own images for windows or has a need to deploy Windows a certain this can be a handy little tool for when the image might need to be repair, or something might need to be added.    You can add and remove drivers to an offline image or you can do many different things to it.   However I will be talking about the repairing of the image because most of the time we have Hard drives that are mechanical and that can cause problems for the OS when the system get’s corrupt files or hard drive has bad sectors.   Each one of these scenarios can make it even harder for applications to work properly and that is why I use this with systems that have those types of hard drives.   My go to is always going to be this when I suspect the hard drive might be the cause of the issue.

DISM /Online /Cleanup-Image /RestoreHealth

You can run this command and see the progress but this isn’t the only command that helps with troublesome Hard drives.

System File Checker (SFC)

This is another good tool for those who might have issues with the system hard drive or even when you suspect something is corrupt.   I use this from time to time just like DISM for when there is something that isn’t right about the hard drive.   If you use this also with DISM you will see a noticeable improvement of your system response.   You will see that it will be quite handy for those times when you have to get data off the drive before it dies completely.

SFC /scannow

If you run this in command line and wait you will see if it finds bad files or it will tell you what it found.  It won’t be a very informative but it will help.

Check Disk Utility

The Windows Check Utility is the last one of the three that I most often. It helps to check sectors and to check the health of the system and also fixes most of the problematic issues of mechanical hard drives.  So when I says this it can be used on SSD and even NVME but it does his best job on hard drives that have spinning parts.   Most users don’t understand about the volatility of the mechanical hard drive.   So it is very useful to check the disk and make sure there are not bad sectors or fix bad area’s of the hard drive.  This one will need to be rebooted to allow it to be used to its fullest but it is a handy little command when you want to make double sure that you will be able to keep Windows running.

chkdsk [DRIVE] /f

You can tell it multiple drives or just the main drive which would be C: but be warned the bigger the HDD the longer it will take to scan it.  You will also need to reboot to have it do it’s job because it needs to un-mount the drive, if you choice to do the C: drive.   It has in the past helped me out in many different situations and that is why I use these three commands a lot for my job.

What are your favorite commands to use in command line or in Windows General.  I’d like to hear them and find out more useful commands that might help me in my job.   Why not leave a comment and let everyone know.

Microsoft Creates issues

This all started on Friday the 13th, 2023. We all started getting tickets galore for this issue, when we first saw this issue we thought it mgiht be something to do with company’s policies being changed and someone didn’t do their job testing it. Being that I am doing my job and trying to solve the issues that are at hand, I didn’t think twice that it was more globally than just our little corner of the company. As we get back into the office Monday we get even more of these tickets where the icons have disappeared and the little work around we sent out friday night still hasn’t solve some of the issues. Icons from all sorts of places have disappeared including stuff I didn’t even think would happen.

Well there it is, it seems Microsoft released an update that caused all the icons to disappear or not to function at all. I’ve been dealing with this issue for the past 5 days as our company scrambles to get the issue resolved for their employees. We’ve learned a few things and I will be glad to share it with you.

Icon restoration

There are several ways I’ve found that works to help restore the icons in the Start Menu.   One of the easiest way is to go to “Add and remove programs” and modify the app that isn’t showing up and Repair or reinstall if that is the option.  This is what we had to do at our location but that isn’t all we are having to do.  We are also having to do this for like Adobe and even Office 2016 but I am sure this affects all versions of Office.

Other ways you can restore icon is to registry edit the default icons and make them get repopulated with the right Icons.  I even go into default apps and reset that to help push the apps back into place.

Another way people have found tofix this issue at least with Office apps is to run it siliently and let it repair it selve in the background:

“C:\Program Files\Microsoft Office 15\ClientX64\OfficeClickToRun.exe” scenario=Repair platform=x86 culture=en-us DisplayLevel=False

Microsoft Defender

According to Microsoft it was a the Microsoft Defender ASR rules that caused all this in the first place.   I don’t Know how many IT Admins are happy right now, I am sure not because of all this that happened but It really makes you wonder how this got past the pre-test phase and how anyone would push out an update like this that caused so much trouble.

Many people are wondering how this happened but My real question is will it happened again.  This isn’t going to be a big post but a short one to help those fix the issue at hand and hopefully we get it solved as quickly as possible and everyone get’s back to a normal routine.

Is it time to say NO to LastPass?

Lastpass Recent Incident

Lastpass in the recent has been an excellent password manager and I was one of the many supporters.   The problem with it now is that it is going down hill.   They seem to not want everyone to know just how severe this incident is and have not really done the job that we should of expected.   In December they sent out a small notice to people and reference their blog post.   Who is going to go look at a blog post around Christmas.   I sure as heck was to busy with other stuff to worry about a small email telling people to check out the blog post.   LastPass you should of done better and put out the warning bells for everyone to know just how much you screwed up.

In there blog post:

The threat actor was also able to copy a backup of customer vault data from the encrypted storage container which is stored in a proprietary binary format that contains both unencrypted data, such as website URLs, as well as fully-encrypted sensitive fields such as website usernames and passwords, secure notes, and form-filled data.

Vault and Robbers

You see this isn’t very nice how much information they didn’t send out on the email.  This should of been “Danger, Will Robinson, Danger!” type of warning.  Yet, Lastpass didn’t sound the alarm.  Shame on you for not doing the right thing.   As you can see they got your vault data and mine, althought they can’t really use it without the master password but it is only going to take time and then they will have all our passwords for sites across the internet.   There’s the problem they don’t seem to care that it got out.   The threat actors will use GPU’s and other hardware to finally figure out one user at a time their passwords and it could be years before they get to yours or it could be next month depending on how good you Master Password was.   Was it long or was it Short?  What about enterations?  Did you bump it up to keep it from getting hacked and making it harder for them to figure out your Master Password?

The threat actor may attempt to use brute force to guess your master password and decrypt the copies of vault data they took. Because of the hashing and encryption methods we use to protect our customers, it would be extremely difficult to attempt to brute force guess master passwords for those customers who follow our password best practices.

As you can see even Lastpass has stated they will eventually do that to each and every vault password they can, but did you their suggestions?  Probably not and I wouldn’t blame you because we don’t always have time to keep track of what they recommend.

They claim it could take thousand of years for threat actors to crack the Master Password:

f you use the default settings above, it would take millions of years to guess your master password using generally-available password-cracking technology.

However that isn’t alwasy true if they have enough computers put enough effort into cracking a vault it could be sooner and not later.   The way technology is growing and the speeds of comptuer now would mean threat actors could start usurping people processing powers and have thousands of computers world wide to crack the Master Password keys.   That is how Bitcoin came into being but we wouldn’t know it until it could be too late.

Is it time to switch to another Password Manager?

I’m inclined to switch to Bitwarden just because it is open sourced and I really feel like at least I won’t have to worry about my passwords being leaked.   I will also probably go through every site that I visit and change my password and also use 2FA (2nd Factor Authentication) to prevent threat actors from taking control of my accounts.   I’m going to explore my options but I am more and more thinking about going somewhere else where my data can be safer than with Lastpass.  What’s your throughts on this?  are you staying with LastPass or are you Planning to go somewhere else?
