Accessing Win10 file shares from WinXP

Unlike most people I won't say "just stop using WinXP". WinXP is great. Here I was trying to run it in a VMware 15 virtual machine hosted under Win10. And I couldn't get XP to browse or map shares using net use h: \\m5\h$

instead I got error 64

Here's the powershell command that seems to be critical to making it work:

Enable-WindowsOptionalFeature -Online -FeatureName smb1protocol

 Warning! this will cause your computer to reboot.

This is from https://docs.microsoft.com/en-us/windows-server/storage/file-server/troubleshoot/detect-enable-and-disable-smbv1-v2-v3 which also helpfully inlcudes a command to check if smb1 was enabled (it wasn't, even though I went thru the optional features GUI to install it, and rebooted as required).

There's a lot of other suggestions made out there. Some that notably don't seem to be required:

"Turn off password protected sharing"

(from https://tinyapps.org/blog/201805170700_winxp_to_win10_folder_share.html). I haven't tried to see if any of the other suggestions are wrong - ie I tried them all before hitting on the magic powershell command above.

Panasonic TH-42PX75U Plasma TV review: input lag and upscaling tested using the piLagTesterPRO

Image
This 720p Plasma TV from 2008 is very unique and quite nice in many ways. It used to retail for around $1300. If you can find one it's a great choice for retro gaming.  Overview/Image quality This is a plasma TV, which generally means at least the following: nearly infinite viewing angles, and jaw dropping weight. That's true in this case as well. This 42" model weights 75lbs.  At native resolution (720p) this TV crops 20 pixels off the top/bottom and 30 off the sides. 480p/i crops 20 pixels off all sides. Both modes have aliasing, too, though it's not too bad. There's really no excuse for aliasing on a TV this big: you know the panel was designed specifically to be a tv. Why not hit 720p exactly? And as for 480p/i, they could have at least offered a zoomed out mode with black borders and 1:1 pixel mapping. But no such luck. There are zoom/stretch options to crop even more, but none that crop less. While the native resolution supposedly is 1366 x 768 it does accept...

piLagTester PRO order page

The piLagTesterPRO measures your monitor's input lag and response time. It is a cheap, full featured add-on to the Raspberry Pi; I provide the sensor and required software, you provide the Pi (a $5 pi Zero is more than sufficient). Although it has a DIY aesthetic, it is quite functional and in fact offers quite a lot more features than the commercial alternatives (Leo Bodnar and the Time Sleuth), and has been tested with over 40 TVs, including 4k models .  Here's what it looks like in action: The pi draws a black background, and then roughly once a second displays a set of target rectangles (top/middle/bottom). You place the sensor over the desired target, and the piLagTester measures the monitor's response starting from the moment the frame of video data is sent over the Pi's HDMI port. This is plotted in the graph, which is sideways for space reasons. The lag tester measures two thresholds. In red it shows how long it takes for the monitor to start displaying t...

A $5 TV Input Lag tester using a Raspberry Pi Zero

Image
High speed monitors are all the rage now, with quoted response times  of 1-4ms. But does that mean that 1-4ms after you make an input (say, jump) you will see that on your screen? No. Often a much bigger issue is  Input lag. This is   the delay between your computer / game console sending a video frame to your display and your display starting to actually show it, and it ranges from 4ms to 80ms. The problem with measuring input lag is that you can't, at least with everyday hardware. The solution for hardware review sites is to purchase dedicated lag testers such as the leo bodnar tester,  timesleuth (both ~$100), or the pi lag tester pro ($40) or use homegrown methods utilizing an oscilloscope ("free" if you already own a $400+ oscilloscope and perhaps a $50k+ engineering degree). Here I introduce a $5 solution (or, "free" if you own the required equipment). What's required: A Raspberry Pi Zero ($5 + S&H from several sources). This single b...
