The computer my sons use sometimes became unreliable a few weeks ago. It would work normally for a while, but rarely could make it through a full day without locking up hard. Here’s how I fixed the Windows 10 random lockups.
I saw an interesting question the other day. A sysadmin had a department asking for more computers, and he suspected the department wasn’t using the machines they have. His IT department didn’t want to go to the trouble and expense to provide more computers to a department that didn’t need them. So here’s how to check computer usage.
Windows 95 vs 98 didn’t seem like a very big deal to me in 1998-1999. With nearly 20 years of hindsight, I still don’t really think it’s a big deal. Here are the differences between Windows 95 and Windows 98.
You probably know how to unzip a file in Windows 10. You double-click on it. But Windows 10 can create zip files too, not just extract them. Here’s how to zip a folder in Windows 10 without buying or installing any additional software.
This option isn’t exclusive to Windows 10. Windows 7 included this functionality too, as did some versions of Windows I wish you wouldn’t use anymore. It’s hiding in a menu that doesn’t get a lot of use these days. But back when floppy disks existed, this menu was the fastest way to copy a file to a floppy. Today it’s the fastest way to create a zip file.
A good trick for the busy system administrator is knowing how to reboot Windows from a command line. For example, I used to push patches on Thursday and Friday, suppress the reboots, then reboot my servers from a batch file starting on Monday. Rebooting from a command line rather than using the Start menu and selecting shutdown or restart saved me countless hours.
As a security professional, I know when systems need to reboot based on seeing Tenable plugin 34543 or Qualys QID 90126 in my scan results.
Is your VMware Fusion screen resolution too small? Mine was. When I pulled up my Windows VM, Windows came up looking like everything was a 4-point font. I know I’m not 25 anymore, but I don’t think I could have read that at 25, even. Fortunately the fix is pretty easy once you know where to look.
I’m not sure how well this works in operating systems other than Windows, but if you run Windows 10 in a VM like I do, this seems to fix it.
My Windows 10 sound stopped working suddenly. One day it worked, the next day, it quit. Nothing else changed–I hadn’t even rebooted. If, like me, you experience Windows 10 sound not working, here’s a quick fix to try that should take you less than a minute.
My symptoms were simple. My web browser quit playing audio. Muting and unmuting didn’t help. Changing the volume didn’t help. I tried a different browser and it wouldn’t play audio either. Then I fired up Windows Media Player and tried to play a song. I got silence. Then I got a red X next to the song that didn’t play. If this sounds familiar, keep reading. I can probably help you.
Windows versions from XP onward include a built in firewall. But is Windows Firewall enough protection?
Yes. And no. Security answers are almost always complicated. But I’ll explain.
Sometimes it’s faster just to type a command than to dig around in the start menu. That’s especially true for many sysadmin tasks. Knowing the command line for active directory users and computers can save you a lot of time.
