Windows 10 can’t connect to this network – solved

After upgrading to Windows 10, when I unhibernated my laptop the next morning, my wifi connection didn’t work. Forgetting the network and reconnecting didn’t help–I’d get the message that Windows 10 can’t connect to this network.

The problem seemed to be in the power management.

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.

Share a Windows 10 printer by UNC

Windows 10 uses homegroups, but if you have systems that don’t understand homegroups and want to share a Windows 10 printer by UNC (the old school way to share a network printer), it’s not obvious how to go about doing it.

I couldn’t find a way from the GUI, but it’s still possible to share the printer from a command line.

Compress system files doesn’t show up in Disk Cleanup

One of the new features of Windows 10 is better file compression, which was intended to help Windows fit better in low-resource devices like tablets. But it’s helpful on computers with SSDs too. But for whatever reason that option doesn’t show up on mine.

But you can still compress your system files even if the Disk Cleanup utility (which you can also launch from the Free up disk space by deleting unnecessary files control panel) doesn’t show the Compress system files option.

Change your printer’s IP address in Windows

Sometimes you may need to change your printer’s IP address, such as after you rearrange your network. It’s not hard to do, it’s just not always immediately obvious where the settings are.

This method works in Windows 7 and Windows 10. It probably also works in Vista and Windows 8, but I don’t have those versions anymore.

Simple tips to prevent ransomware

Last week at work, I noticed some odd events in an event log, and when I investigated them, I found they were part of a failed ransomware attack. This got me thinking about how to prevent ransomware at home.

Ransomware, if you aren’t familiar, is an attack that encrypts your data and demands a ransom, usually around $300, in bitcoins, and you get a short deadline until it destroys your files. More often than not, paying the ransom is the only way to get the files back, so it’s much better to prevent it.

Download more RAM — Safe? Scam? Joke?

A software developer asked me today about a website called Download More RAM. I don’t think he heard my other coworkers snicker. He asked if it’s possible to download RAM, then asked if it was a security issue. I said it’s best not to visit it, and spared him the history lesson.

Yes, there’s some history to it.

HP Compaq 6910p upgrades

I spent some time exploring HP Compaq 6910p upgrades because used HP Compaq 6910p laptops are dirt cheap these days. I picked one up for $75 as an alternative to a Black Friday cheapie.

If you look for one yourself, either look for one with a valid Windows 7 or Windows 10 license on it, or get one at a deep enough discount to make it worth your while.

Here’s what I did to turn an outmoded laptop from 2008 into something better than what I could have bought on Black Friday.

Easier application whitelisting in Windows with App Locker

Application whitelisting is the holy grail of security, but it’s always at the top of the list of things people should do but haven’t yet. The reason is because it breaks stuff and it’s almost as impossible to anticipate ahead of time what it’s going to break as it is to fix whatever breaks.

I know. I wanted to do application whitelisting way back in 1997 and failed miserably.

I found a good-enough approach recently, though.

How to add a generic printer in Windows 10

Sometimes you need to add a generic printer in Windows 10.

Windows 10 makes the setup of newer hardware pretty automatic, but if you have a legacy or specialized printer that has to be set up as a generic printer in Windows, the process isn’t intuitive. Here’s how to set it up.
