Před každou úpravou systémového registru je vhodné udělat jeho zálohu. Jak se záloha dělá se dozvíte v návodu Jak zálohovat systémový registr Windows.
Chcete-li zakázat zobrazování miniatur spuštěných aplikací na hlavním panelu Windows, proveďte následující kroky.
Bezpečné možnosti úprav registru a jejich dopad na zobrazení ikon
Stiskněte klávesovou zkratku [Windows]+[R] a do pole Otevřít: napište příkaz »regedit«.
Příkaz potvrďte stisknutím klávesy [Enter] nebo kliknutím na tlačítko »OK«.
V Editoru registru najděte klíč »HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced«.
Klikněte do prázdného místa v pravé části editoru a z kontextové nabídky zvolte »Nový | Hodnota DWORD (32bitová)«.
Poznámka: Pokud používáte 64bitový systém Windows 10, stále je třeba vytvořit 32bitovou hodnotu DWORD.
Novou hodnotu pojmenujte »ExtendedUIHoverTime«.
Novou hodnotu ExtendedUIHoverTime otevřete pomocí dvojkliku myší a upravte položku Údaj hodnoty: na »10000«.
Změnu potvrďte tlačítkem »OK«.
Nyní Editor registru zavřete a restartujte proces Průzkumník Windows.
Restartování Průzkumníka a znovu zobrazené miniatury
Klikněte pravým tlačítkem myši na hlavní panel Windows a z nabídky vyberte »Správce úloh«.
Pokud vidíte Správce úloh ve zjednodušeném zobrazení klikněte na »Více informací«.
Na kartě Procesy najděte proces s názvem Průzkumník Windows. Klikněte na něj pravým tlačítkem myši a vyberte možnost »Restartovat«.
Po najetí kurzorem myši na spuštěnou aplikaci se již miniaturní náhled nezobrazí.
Obnovení původního stavu registru a řešení mírně zobrazených položek
Chcete-li vše vrátit do původního stavu, smažte v Editoru registru hodnotu ExtendedUIHoverTime a restartujte proces Průzkumník Windows podle návodu výše.
Upozornění na zobrazené položky při startu a možné nejasnosti
When I open my task manager and look at my startup items, there is a file entitled "program". When you right click on it the properties is grayed out as well as open file location. I ran sfc/scannow but the results returned with no problems. This question was migrated from the Microsoft Support Community. I had this and was concerned it was malware. But I found that right clicking on one of the shown categories e.g. "Name" or "Status" you can enable many other categories. located. I found it to work in Windows 8.1 by doing the following in the image below. Choosing "Command line" give the directory path to the file e.g. Did you find out where this file is or how to get rid of it? I have the same file and it just showed up however I can't click the open file location. I was able to see my start up information with the information you provided. Oddly enough, in the software environment under startup it shows 11 programs which all correlate to what is being shown through the normal startup manager. starup manager shows 12 programs enabled including the mystery "program". So the program through software environment is not showing the process called "program". In Settings -> Startup, listed under Startup Apps, I found an app that was simply called "Program." I opened the Task Manager and navigated to the Startup tab. I was able to find a question thread on this site titled "File called "program" listed as a file under my startup applications in Windows 8", and learned that a number of other users have had the same issue. For those seeking closure, I think I have found the answer. It is not caused by any specific program or programs; it is caused by a typo in the command line that is used to run the app at startup. In my case it was Surfshark (as pictured below), but it could be anything. Specifically, it could be anything found in the "Program Files" or "Program Files (x86)" directories. If the double quotes around the file location are omitted or incorrectly placed (as pictured below), then Windows will attempt to open a file called "C:\Program" instead of the actual intended app. This is why the file appears as "Program" in the startup apps list. Of course there is no actual file or folder called "C:\Program," so the command does nothing; this is also why there are no properties, file location, publisher etc. available to display. Because it does nothing, it is harmless, but it can be disabled so that the command is not run at startup. If you don't like seeing it on the list, or if you want to fix it etc., the command can be deleted or edited through the registry. This question was migrated from the Microsoft Support Community. Thank you for this information! Exactly what I was looking for.
