Perhaps, it was in Windows 8 or when I was getting early builds of Windows 10, but no matter what I did, I couldn’t get Windows 10 to change the pre-login background screen that was selected at some point. It was stuck on the stock cave beach image of img100.jpg and it eventually drove me crazy.
Windows 10 only rendered the image at reboot or before I logged-into the laptop. After I logged-in, any screen lock or wake from sleep used my background image setting. It might be stuck on a different image of the stock ones from Windows 8 or 10 on your laptop. It always bugged me, but finally I had to do something about it. There are numerous posts on the web on how to handle this or variants of this. I always assumed there was just a problem because of the beta nature of the earlier Windows 10 builds and eventually it would work itself out. It never did.
All the various tricks on the web to change the background and lock image in Windows 10 didn’t work for me. All the regedit hacks, search and destroy ideas out there were of no help for me to kill this pre-login background screen. But, I finally killed it. Here is what I did.
Make sure you have folder item view options to show hidden and system protected files.
Go to C:\ProgramData\Microsoft\Windows and right-click SystemData if it exists.
Change ownership of SystemData so you can full control it.
Under SystemData, I had a couple of subfolders
Under the S-1-5-18 folder, there was a Read-Only folder
In that folder, there was an odd little “LockScreen_Z” folder with three images of that img100.jpg pic.
I moved that LockScreen_Z folder out to the desktop and did a reboot and I was freed from the image!
For some reason, Windows 8.x or 10 created this C:\ProgramData\Microsoft\Windows\SystemData\S-1-5-18\ReadOnly\LockScreen_Z directory that held on to that pre-login screen image no matter what I tried to do via regedit or via deleting every img100.jpg under C:\Windows.
If you suffer from this same issue, and Personalization or regedit hacks never worked, seek and destroy that LockScreen_Z folder. I hope that helps.
Just installed. I have to say, I like it. It’s all Windows 8.1 but the Windows Explorer is more Windows 7. It has only been a few hours, but I’m doing fine on my Lenovo Yoga 2 Pro.
The killer feature for me is the implementation of virtual desktops. Apple never got it right and the various applications for OS X and Windows never really got it right. If you are used to the flexibility of the GUI in Linux or Solaris, you miss this when you don’t have it. The ability to keep applications open and maximized but off into their own desktop for organization is just such a great productivity aid.
I had an issue running Perl in Cygwin. I could install the modules I needed, but was unable to compile Term::ReadKey due to sgtty or some other challenges. I kept getting annoying messages around perl like this with “sgtty not found” and it seems to be an eternal issue. I found bug reports back to 2000!
I tried many different tactics within perl, but nothing worked. Turns out, there is a cygwin package you can install directly for this issue. You can run the setup.exe or setup64.exe for cygwin and select the
package to get the module going in perl under cygwin. You are also better-off long term on getting apt-cyg going in the cygwin environment to query and install packages easily in the environment and without the need to fire-up the setup.exe app each time you want to install a package.
If you have an ultrabook that can dish great resolution, Windows 8.1 does some interesting things around scaling in the UI. This has caused me some grief with my Lenovo Yoga 2 Pro that wants to dish 3200×1800 natively.
Windows 8.1 will try and do some scaling options for you and it feels like a bunch of adjustment areas that you just need to play with for a while to get what you like. You have scaling, screen resolution, magnifier, and other options in the various display settings to mess with. But, even if you do that, some apps can look a little blurry. This is along the lines of the issues Mac users have with their retina screens.
No matter what you do with the various display settings, you should also look at messing with the compatibiltity settings in Windows for the apps directly. If you have a shortcut pinned to your taskbar or on your desktop, you can right-click and go into properties.
Once in the shortcuts properties, you can check a flag to disable the scaling Windows wants to do to to the application rendering under the compatibility tab. Check the disable scaling checkbox.
In my testing, this has helped tremendously on many different occasions. For example, on GoToMeeting it has been critical to kill the blur as Windows tries to offset the high DPI with scaling up or down. You can right-click the GoToMeeting icon when it is running to change the flag. It does require the application to be restarted to take effect.
This is not a silver bullet to fix blurred windows or fonts and it should be tried after you have done what you can inside the various display and fonts scaling areas in Windows Control panels.
