0xc1900201 error installing Windows 10

Are you getting a 0xc1900201 error installing Windows 10? I got both that and 0xc1900200. Here’s how I fixed it.

I upgraded my venerable Dell E1505 to Windows 10 over the weekend. It was harder than it needed to be, but I got it running. It’s an old machine, but the CPU is fast enough to run Windows 10, and if you max out its memory and put an SSD in it, I think it may even run Windows 10 better than it ran Windows 7.

Here’s how I got it working.

Types of Lionel knuckle couplers

Types of Lionel knuckle couplers

There have been three major types of Lionel knuckle couplers produced since resuming train production in 1946. Lionel knew it would have to make a splash when it brought its trains back after the end of the War, and the knuckle coupler was one of the keys.

Two of these coupler types are compatible with one another, but one has a gotcha.

Solve the NSIS error

Solve the NSIS error

I was trying to install some software last week and I got an NSIS error. The message certainly suggests corrupt downloads, but corrupt downloads are relatively rare, and when they happen, redownloading it ought to clear that up. Getting two of these failures in a row with different programs is really a freak occurrence, so I started looking for another problem.

Microsoft Security Essentials alerts – don’t call “Microsoft”

Last Tuesday night my oldest son came into the room and told me he thought one of our computers was being hacked. So I kicked into incident response mode and walked into the other room to be greeted with a computer loudly telling me that Microsoft Security Essentials was unable to clean a virus and to immediately call Microsoft.

Instead I immediately shut down the computer. Here’s why.

Remove and install Marx coupler springs

I did not invent this technique. Last week Al Osterud, a veteran Marx collector of many decades, shared a technique for removing and installing Marx coupler springs without the skills and steady hand of a microsurgeon.

All you need is a piece of 1/8-inch K&S square tube, which resembles the tool Marx used to install them at the factory, and a toothpick or a straightened paper clip. Marx wouldn’t make anything that wasn’t easy to put together, which made its couplers so maddening to work on. Why was it easy in the factory and nearly impossible at home? With the right tools, it is indeed easy.

Double-check your security with Qualys Browser Check

Double-check your security with Qualys Browser Check

In the past, I’ve recommended Secunia PSI as a way to keep your systems up to date. I know from my own experience that it helps, but I also know it doesn’t work 100 percent of the time.

When it comes to security, nothing is more critical than making sure your updates are applying correctly. That’s where my employer comes in, with Qualys Browser Check.

A DD-WRT USB print server

A DD-WRT USB print server

If your router has a USB port and is running DD-WRT, you can turn it into a DD-WRT USB print server. It can still do wireless duty while it allows your computers to print to your wired USB printer over your wired or wireless network. It’s not very intuitive or user friendly, but it works. Here’s how to set it up with Windows 7. Other Windows versions will be about the same.
