What’s my Windows version

You’ll probably get asked this once or twice. Especially when your Windows computer is not working right, and you are running all over the Internet trying to look for answers. Perhaps would-be good Samaritans might ask this off you as well.

And you reply, “Windows 10”. But rightfully so.

After all, isn’t that the Windows that is installed on your machine right now. Well, yes. Then again, no. No not in the sense that you are wrong. But sometimes the answer to the question of what Windows version is installed on your PC might be something else. Sometimes support may ask you this, and likely they will tell you how to give them the answer they are looking for. If you don’t already know this, then this can save time and misunderstanding. Below are the steps on how to get that information.

What version is my Windows?

  • Go to the Start Menu. Click it. Press the Windows key
  • Type “Run”. The shortcut key is Windows key + R.
  • Type “winver” in the field labeled with Open. You may also type winver in the search box on your taskbar if you have that one.
  • Click OK or press enter
  • Small dialog Windows will pop out title – About Windows.

The information will be found on this pop up window. On the first few lines you should see something like:

Microsoft Windows
Version 2004 (OS Build 19041.630)

Note: Don’t include quotes when typing in those words in the steps.

Is there a Clipboard for Windows 10?

What are the freely available Clipboard programs, if any, for Windows 10? Are there such? I don’t want ads in it and I prefer it simple as possible. No crazy or complex features. I’m only after a simple copy-paste of the short history of what I’ve copied on my desktop. I find this useful for my productivity. I somehow always ending up in open a Notepad and copying the items in there. It works but a clipboard would be better in my opinion.

ANSWER

Windows 10 already comes with a built-in Clipboard Manager. This was from an update some time ago. However it is not enabled by default, buried somewhere in the Settings and you will have to activate it. This feature is not very well known. But it is there and it works as expected.

To activate:

Open Settings via any of the following ways:

  • You can either search for it if you have that search bar on your Windows taskbar.
  • Start typing “Settings” when you have the Windows Start Menu opened.
  • Open the Start Menu then, then click on the Gear icon on the left hand side of the menu.
  • Windows + i shortcut key combo.

Once you are in Settings, go to System. That should be the first icon entry at the top.

You will be taken to another page where there are items at the left hand side. Scroll down and find Clipboard.

Under Clipboard history, toggle the button to On.

To get to your clipboard history, simply press Windows + V shortcut key combo. It will appear as a floating box over your last active application. Otherwise, it will show up on the right side of the desktop on top of the system tray.

The clipboard can contain a max of 25 entries. It is a FIFO (first in, first out) stack so the oldest entry will go out first once that entry limit is hit.

It supports plain text, HTML and images up to 4MB size.

Your clipboard history can be synced across your Windows devices. Be warned that if you enable this it means you are allowing Windows to save the history on Microsoft servers. Make sure you don’t have sensitive information in there when the Sync functionality is enabled.

Combining Two Containers

I’m working on a Windows laptop and running Docker for Windows on it. I want to run an Ubuntu container with a specific version and a MySQL server on it. So the question is, do I have to download MySQL on the Ubuntu container or can I run 2 containers (Ubuntu and MySQL) and combine them? How do I combine these 2 containers?

Printing all existing windows on a windows container

I wrote a simple cpp console app that prints all the open windows titles:

Printf("hellon");
for (HWND hwnd = GetTopWindow(NULL); hwnd != NULL; hwnd = GetNextWindow(hwnd, GW_HWNDNEXT)) { 
    if (!IsWindowVisible(hwnd)) continue; 
    int length = GetWindowTextLength(hwnd);
    char* title = new char[length+1];     
    GetWindowText(hwnd, title, length+1); 
    printf(" Title: %s", title);
}

The main reason of that app is to monitor the windows another exe is opening.
However, it only prints hello and no titles at all.
While it does works on the host windows os and prints all the existing windows on it.
What is the difference on docker and how can I make it work similarly?

How to turn off mouse acceleration in Windows 10?

After the recent Windows 10 update, my mouse has had mouse acceleration on even though I turned it off. I also uninstalled Logitech G Hub (I have Logitech G302 gaming mouse) and reinstalled it. I tried doing clean boots, removing the device from the computers through Control Panel, but nothing has worked so far. What should I do?

Dualboot problem with windows 10 and ubuntu in MSI

I have installed windows 10 and ubuntu 20.04 on my laptop, in general it seems that everything works fine.
The problem I observe, is when I’m in ubuntu, and I reboot to enter windows, there are configurations that are reset, like configurations with the graphic card (nvidia), sound card or wifi.

Similarly, when I’m in windows and I switch to ubuntu, the first time I log in, the wifi card never works in ubuntu, I have to reboot twice for ubuntu to detect it…

I was reading that this may be due to the UEFI configuration, which should be using legacy mode. Should I format the disk, switch modes, and reinstall windows + ubuntu?

Also, in other computers I’ve had, I used to have problems changing the time, when I changed OS, but in this case, I find it curious to observe that not only the hour changes but also the minutes, I don’t know if it’s something also rare.

I’ve put all the problems together because I don’t know if they are all due to the same mistake…

Thank you very much in advance

Installing Certificate Authority

I have used this guide to install, in my lab a 2-tier PKI on Windows Server 2019
https://social.technet.microsoft.com/wiki/contents/articles/15037.ad-cs-step-by-step-guide-two-tier-pki-hierarchy-deployment.aspx
I know that guide is pretty old but it seems to have been updated pretty recently. Some steps are slightly different in the newer Windows version but nothing that can’t be figured out. The only deviation from the guide is that I have combined the the roles of the issuing (CA02) and the CDP/AIA publisher (SRV1). Other than that I followed the guide step-by-step (or at least I think I have, there are a couple of parts that are not very clear). I have redone the whole thing a couple of times. I keep winding up with the same issue:
I cannot validate the ldap connections for AIA, CDP or DeltaCRL in PKIView. I also notice that the share location that I create during the initial setup of the issuing server has somehow changed to the CertEnroll folder under certsrv in system32 rather than C:CertEnroll where I created it. How the heck does that happen?!? I am not sure at what point in the process that changes. I’ve just noticed it when I am troubleshooting the pkiview fail after completing all the setup steps. I am obviously most concerned witht he PKIView failure, just really curious as to why that share location changes. Thanks for reading.Screenshot of PKIView

Are there security reasons for prohibiting universal mac address modification?

Background

In a standard 48-bit MAC address, the 7th (most significant) bit specifies whether it is a universally-administered address (UAA) or a locally-administered address (LAA).

If it is 0, then the MAC address is a UAA and the first 24-bits are the organizationally-unique identifier (OUI) of the manufacturer of the network interface card (NIC).

If it is 1, then the MAC address is just an LAA.

Question

Many drivers and NIC’s often allow users to modify the MAC address of their device.

But, it seems Windows does not allow modifying mac addresses to universal ones (i.e., UAA’s): https://superuser.com/questions/1265544/

What is the reason for this restriction? Are there security implications if this was not the case? Or, perhaps, is this merely just to prevent someone from spoofing a device as some legitimate company’s network communications product? (to their ISP)

Login names between sub domains in Active Directory

If I create two subdomains (sub1.domain.com and sub2.domain.com) to my parent domain (domain.com) can different users have the same login in the different subdomains? Or does logins need to be different across the forest.

  • jsmith@domain.com
  • jsmith@sub1.domain.com
  • jsmith@sub2.domain.com

Is this perfectly fine or will sub 1 and 2 conflict with the parent domain. Or will all 3 conflict with eachother?

Make host header correct from upstream

I configured simple load balancer scheme on the windows:

upstream app.local {
    server app1.local:8001 fail_timeout=10s max_fails=10;
    server app2.local:8002 fail_timeout=10s max_fails=10;
}

server {
    listen 8000;

    location / {
        proxy_pass http://app.local;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $remote_addr;
    }
}

Changed hosts file like this

127.0.0.1       app.local
127.0.0.1       app1.local
127.0.0.1       app2.local

All fine, but my web servers behind app1.local and app2.local receive incorrect headers Host: app.local and therefore don’t want resolve requests. I readed
the post where the same problem but top answer not resolved my and i don’t want to use the double layer proxy option straight off.

What firewall should I use?

What is the most comprehensive free firewall solution available for Windows? Personal machine, not work machine. I see a ton of choices online, but not sure which one to pick.

Author: PerpetualLearner

ANSWER

For home use I am fine with the built-in and free Windows Firewall (or Windows Defender Firewall) most of the time. It serves its purpose. Does the job. Not overwhelming to use. Customizable enough.

I would also explore the security options that comes with my home router. Many have it included nowadays, and with a little tweaking, should be able to add an extra layer of protection to one’s home network..
