Sometimes RDP limits you to 2048 pixels vertical (or 4096 pixels horizontal)
Just found out why on some Windows versions, the RDP sessions form my 4K monitor has some small black bands on top/bottom: older versions of Windows limit their RDP server to 4096 x 2048.
A 4K monitor will not hit the width limit (as 4K cheats: it is usually “just” 3840 pixels wide), but it does hit the height limitation (2160 is slightly more than 2048: you miss 112 pixels that show as two small black bands).
A 5K monitor is worse: it will hit both limits (5K does not cheat: at 5120 × 2880 it is exactly 5*1024 pixels wide) so you miss 124 pixels horizontally and a whopping 832 pixels vertically.
Don’t buy a 5K monitor yet if you do a lot of RDP work to older Windows versions.
The link below has a table listing various Windows versions, but it omits end-of-life versions so I’ve done some testing: Windows XP, Windows Vista, Windows Server 2003 and Windows Server 2003 R2 share the same limitations as Windows Server 2008 most likely because their latest service packs share the same RDP 6.1 version.
I updated this in the table:

I’ve had a SUA3000XLI for years using the USB cable and default Windows support as PowerChute Personal Edition would fail to recognise it and abort installation (so I could not use APC drivers as described on youtube).
A while ago, Liander – the energy distribution company – wanted to replace both the gas and electricity meters to become “smart” during day time. The server configuration load was heavy enough for Windows to indicate the UPS would last about 30 minutes. At night that’s not much of a problem but during 1 hour replacement day-time it would be a problem.
So I bought a SUA48XLBP battery pack (and a SUA039 cable as the cable wasn’t long enough to keep an inch or so air space between UPS and battery pack) so the battery would last about 3 times as long.
Windows would still show it would last about 30 minutes. Strange. So I started looking around and it appeared the SUA3000XLI needed calibration which requires PowerChute. Since PowerChute won’t work, I was almost back at square 1. Almost, as I know knew it required calibration.
In the past I had come across apcupcd but that was a long time ago when it supported a limited set of operating systems and a limited set of features so I never installed it.
But when searching how to calibrate the without using PowerChute, it quickly appeared that the apctest part of apcupsd can do just that: soft calibrate the UPS/battery combo. There are some steps and prerequisites (the most important ones are to turn off the apcupsd and provide enough load and 100% battery charge at start).
Spoiler: the combined UPS/battery-pack now lasts for almost 2 hours which is long enough.
Installing apcupsd
I’m describing this from a Windows perspective and it’s dead easy:
- download the latest release
- run the installer
- allow the driver to be installed
- indicate it’s OK to install an unsigned driver
- now Windows won’t recognise the UPS any more, but in a few steps the apcupsd and helper program will
- update the configuration file (no changes needed when it’s a USB connected one)
- wait for the service to start
- wait for the apctray helper program to start
- look in the “system tray” for apctray helper program icon
- optionally configure your system to auto-start apctray after logon
The USB connection to the UPS delivers slightly less options than using a serial cable
Using a serial cable instead of a USB one

Note this won’t affect web-dav shares like \live.sysinternals.com\DavWWWRoot as that uses ports 443 and 80.

One day I’m going to need this: Make A Bootable Windows 10 USB Install Stick On Linux With WinUSB Fork ~ Web Upd8: Ubuntu / Linux blog
So I’m glad WinUSB (which hadn’t been maintained for a long time) got forked on github by slaka.
Since my day-to-day unix-like system is OS X, I’d love a good working solution there too which means I probably need to investigate a bit along these lines:
- Using diskpart in a Windows VM (which is kind of backwards):
- Using Disk Utility and UEFI (only works for Windows 8 and up):
- Using Boot Camp Assistant and a modified Info.plist (which for El Capitan needs some extra work):

PowerShell 4.0 is madly in love with “English (United States)”
A long time ago I started writing up my blog post like this in March 2015 when I bumped into this the first time when upgrading from PowerShell 2 to PowerShell 4:
It seems there is no real workaround:
Good and not so good news: after reading the below linked posts, this is what works:
- PowerShell 4 and up works fine with any [Wayback] Lucida Console size (including 12) and boldness
- only when the “Language for non-Unicode programs” is set to “English (United States)”.
- PowerShell 4 works fine with [Wayback] Consolas on any size and boldness
- for any “Language for non-Unicode programs”
So if you’re like me and switch between “Dutch (Netherlands)” and “English (Ireland)” a lot (both use the EURO as currency, but have distinct enough other locale settings to cover a lot of European stuff) then you need to get used to the Consolas font.

Edit 20210930: a possible solution
I need to fire up some old systems having PowerShell v3 or v4 on them to test the below possible solution.

One of the things I figured out with Windows 7 and up is that when logging in over RDP an existing user would be disconnected unlike Windows XP that would logoff the existing user.
If you want them to logoff there are basically two options:
I will dig into the scripts one day as I’ve not needed this too often (I use Task Manager for now).

Windows has the built-in ability to function as VPN server, although this option is hidden. This trick works on both Windows 7 and Windows 8. The server uses the point-to-point tunneling protocol (PPTP.)

One day this might come in handy though I need to investigate a bit more on PPTP security issues first: might need to go for L2TP/IPsec instead.
Later: indeed, I should follow Don’t use PPTP, and don’t use IPSEC-PSK either (via: CloudCracker blog)

One file kept getting added to the git modified list: service/src/main/MySOAPdefinition.pas.
It was part of a repository that had been migrated from SVN (more on that in a future blog post) and along the way been renamed in directory service/src/main from MySOAPdefinition.pas to MySoapDefinition.pas. SVN (and TortoiseSVN) don’t object to this. But git does.
You’d see this on the command-line:
>git status
On branch develop
Your branch is up-to-date with 'origin/develop'.
Changes not staged for commit:
(use "git add ..." to update what will be committed)
(use "git checkout -- ..." to discard changes in working directory)
modified: service/src/main/MySOAPdefinition.pas
no changes added to commit (use "git add" and/or "git commit -a")
>git add service\src\main\MySoapDefinition.pas
>git status
On branch develop
Your branch is up-to-date with 'origin/develop'.
Changes not staged for commit:
(use "git add ..." to update what will be committed)
(use "git checkout -- ..." to discard changes in working directory)
modified: service/src/main/MySOAPdefinition.pas
no changes added to commit (use "git add" and/or "git commit -a")
Basically the add would do nothing.
On Windows, this is how to get around this:

Very interesting question and answers: windows 7 – Available memory differs by several GiB from what is installed – Super User.
Basically the missing memory can be due to:
- Windows licensing limitations
- Mapping of device memory into virtual memory space (especially on x86 systems)
This affects both server and client versions of Windows. Client versions are more restrictive because of the vast amounts of potentially faulty drivers involved.
Some links (read the full question for details):
