It is no longer the most efficient way of doing it in 2023. Instead, you can use WSLg. Introduction Using Linux GUI Apps with WSLg - TL;DR version Using Linux GUI Apps with WSLg - Full Version Getting To This Answer Introduction WSLg is a convenient and efficient solution for running Linux GUI apps on Windows, providing better performance and compatibility than using an X server, but most importantly giving your Linux app a feel of a native Windows application, which can even be launched from the Start Menu.Victor Zakharovdevelopmentwindowssoftwarelinuxwsl2/posts/2015-08-25-lock-file-tool/Tue, 25 Aug 2015 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Thu, 30 Jan 2020 20:47:42 -0500/posts/2015-08-25-lock-file-tool/This command line tool did not work for me (access denied): http://www.jensscheffler.de/filelocker. This Windows UI tool worked perfectly: https://code.google.com/p/lockfile/downloads/detail?name=LockFile.exe&can=2&q=. It has less options, but it does a read lock, which is what I was looking for.Victor Zakharovdevelopmentwindows/posts/2014-01-20-windows-7-performance-host-guest/Mon, 20 Jan 2014 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Sat, 05 Jun 2021 11:36:56 -0400/posts/2014-01-20-windows-7-performance-host-guest/I am running Windows 7 x64 both as a host and a guest VM using VMWare Workstation v9. Here are the figures of Windows Experience Index for each instance, so you can estimate virtualization efficiency: Host Windows 7: Guest Windows 7 - VMWare Workstation v.9: Guest VM is allocated 2 cores, out of 4 cores total on my Intel i7-4770. As you probably have heard, Windows 7 uses logarithmic scale for its performance score.Victor Zakharovwindowsvirtualizationbenchmark/posts/2014-01-13-persistent-drive-mapping-windows-2012/Mon, 13 Jan 2014 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Sat, 05 Jun 2021 11:36:56 -0400/posts/2014-01-13-persistent-drive-mapping-windows-2012/Problem By experiment, I discovered that Visual Subst no longer works in Windows Server 2012, as good as it did in previous versions of the OS. Specifically for the purpose of referencing a DLL from a locally mapped drive. See below for more information. Assumption In Windows 2012, 32-bit and 64-bit processes use separate network drive mapping (later - Z:). Did not find a confirmation on the internet. Research 32-bit processes understand subst command, 64-bit need something else.Victor Zakharovwindows/posts/2011-08-10-windows-firewall-auth-failed-to-start/Wed, 10 Aug 2011 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Sun, 01 Mar 2020 16:02:16 -0500/posts/2011-08-10-windows-firewall-auth-failed-to-start/Alright, I struggled to make it work for a total of 5 hours. The original issue was that Firewall could not start because of error 1068 - some dependency failed to start. The symptoms: outgoing connections work, incoming are blocked. I drilled down to Windows Firewall Authorization Driver malfunction. Tried just about every advice out there on the internet - nothing worked. Having gathered enough frustration, I thought it would not hurt to uninstall this crappy thing from Device Manager.Victor Zakharovdevopswindowsfirewall/posts/2011-08-09-drive-letter-not-available-for-mapping/Tue, 09 Aug 2011 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Sun, 01 Mar 2020 16:04:40 -0500/posts/2011-08-09-drive-letter-not-available-for-mapping/Somehow my Windows 7 partially remapped a drive letter to another entity. It happened suddenly with some unexpected behavior. I noticed it when it could no longer connect to a network share. I removed the mapping and tried recreating with no success. The drive could not be deleted. Restarted, the drive is not mapped, yet it’s still not available. Started googling and came across this forum discussion. The problem is related to non-active drives still reserving a letter.Victor Zakharovdevopswindows/posts/2011-03-22-wmi-query-incorrect-class-win-2003-r2/Tue, 22 Mar 2011 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Sun, 29 Mar 2020 19:47:31 -0400/posts/2011-03-22-wmi-query-incorrect-class-win-2003-r2/I got this ‘Invalid class’ error when querying disk performance data: Win32_PerfFormattedData_PerfDisk_LogicalDisk The server was running Windows 2003 R2 Std x64 SP2, so I used this article to ‘detect and repair a corrupted WMI Repository’: rundll32 wbemupgd, RepairWMISetup Well, it did not work for some reason. A little more googling led me to a blog, where Mike (the author) suggested two additional actions: First winmgmt /resyncperf Then winmgmt /clearadap Just executing (1) did not solve the problem for me, while doing (2) after that worked perfectly.Victor Zakharovwmiwindowsdevops/posts/2011-03-09-how-to-update-eset-remote-admin-server/Wed, 09 Mar 2011 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Sun, 29 Mar 2020 19:44:44 -0400/posts/2011-03-09-how-to-update-eset-remote-admin-server/Solution For those who don’t like to read stories, here’s the extract: Proceed with installation, even despite it appears to be a clean install. In the end you will get a working version, with all configuration preserved. Story Today I got a notice from ESET Remote Administrator Console about new updates being available and a prompt to get them from the website. I downloaded two new executables (Server and Console) for version 4.Victor Zakharovwindowsdevops/posts/2011-03-02-acronis-trueimage-2010-home-not-user-friendly/Wed, 02 Mar 2011 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Sun, 29 Mar 2020 19:47:31 -0400/posts/2011-03-02-acronis-trueimage-2010-home-not-user-friendly/I recently upgraded to a larger hard drive and went from 1TB -> 2TB. Now the task was to make backup task in Acronis use the new location. I created new destination folder, moved all previous backups there. Then I changed Acronis backup task to do backups to the new place. Quite obvious so far, isn’t it? Not with Acronis. Although it picked the right full backup file to append to (shown on configuration screen), it failed on the next incremental backup:Victor Zakharovwindowsdevops/posts/2011-02-21-ntfs-compression-worth-it/Mon, 21 Feb 2011 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Sun, 29 Mar 2020 19:20:47 -0400/posts/2011-02-21-ntfs-compression-worth-it/Some time ago I researched compression in various systems, ranging from software archivers (like WinRAR, WinZip etc.) to database solutions (like Oracle data compression). Then I figured there is one more type of compression that I did not touch yet - NTFS compression. People on the net say it’s pretty much useless, still I decided to give it a try. And here is what I came up with: Folder name Uncompressed size, MB Compressed size, MB Space savings, MB Space savings, % Proof/screenshot Victor (Personal) 11820 10130 1690 14.Victor Zakharovwindowsdevops/posts/2011-01-01-mouse-lags-in-top-right-corner/Sat, 01 Jan 2011 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Sun, 29 Mar 2020 19:27:29 -0400/posts/2011-01-01-mouse-lags-in-top-right-corner/Let’s hope you keep your computer up-to-date. You happen to own an ATI video card, and updated to Catalyst 10.12. Now most likely you have this weird mouse lag in the top right corner of the screen. Some people report it appearing in other corners as well, both while gaming and staying on Windows desktop. Read here for more information about people experiencing this.

This is especially important if you are running your system on precious SSD space. Luckily, you can get rid of that file, and the fastest way is to use command prompt. These guys say it should be elevated, but it worked just fine for me, probably due to disabled UAC.Victor Zakharovwindowsdevops/posts/2010-11-13-tortoise-svn-no-overlay-icons-after-upgrade/Sat, 13 Nov 2010 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Sun, 29 Mar 2020 19:36:02 -0400/posts/2010-11-13-tortoise-svn-no-overlay-icons-after-upgrade/Just updated my TortoiseSVN client at home from 1.6.9 to 1.6.11 and found that I can no longer use overlay icons, either in Explorer or in Total Commander (more used to the latter). It appeared as if Tortoise shell extension was not loaded. I tried a restart - same thing. Googled on it and found their FAQ, which didn’t help either. A little more googling brought me to this page.Victor Zakharovwindowsdevops/posts/2010-10-07-virtualization-cannot-connect-to-server-hyperv/Thu, 07 Oct 2010 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Sun, 29 Mar 2020 19:42:01 -0400/posts/2010-10-07-virtualization-cannot-connect-to-server-hyperv/You should be reading this article if you are seeing any of the two (or both) screens: Windows Security / Your credentials did not work Your system administrator does not allow the use of default credentials to log on to the remote computer XXXXX because its identity is not fully verified.

If you consider Exchange with the above requirement, you probably have the same problem we used to have. Memory consumption! STORE.EXE takes almost all available memory, no matter how much you allocate to the server. This might not seem like a big problem… until you disable page file, to make sure you server runs on memory, and not on a hard drive.Victor Zakharovwindowsdevops
