How to remove MS Calculater Powertoy for WinXP to Win7?

Yesterday, I tried to uninstall MS calculator Powertoy from programs and features, in Normal and safe mode, but I failed.

After clicking on info from Windows Installer uninstall "Prepare to remove" appears. So I need to allow 89700.msi - setup for Powertoy Calculator - located in the C:\Windows\Installer\ folder to do the job, and a moment later, another warning appears: "Powertoys requires Windows XP or service pack. They will not work on a version of Windows earlier or later than Windows XP", which interrupts the uninstall.

All you need to do is delete these three files in the C:\Windows\System32 directory.

calcpt.chm
PowerCalc.exe

PowerToyReadme.htm

Another step is to remove the reference program installed in the registry, which is displayed in the dialog "programs and features". Use the following steps:

Click Start, type regedit.exe and press {ENTER}

Navigate to the following branch:

HKEY_LOCAL_MACHINE

\SOFTWARE

\Microsoft

\Windows

\CurrentVersion

\Uninstall

\{B37C842A-B624-46B8-A727-654E72F1C91A}

{B37C842A-B624-46B8-A727-654E72F1C91A} right-click and choose export. Save the branch to a REG file.

Right-click {B37C842A-B624-46B8-A727-654E72F1C91A}, and then choose Remove.

Exit the registry editor.

  • Urgent: How to remove all the cards for a crawler through SQL

    People,

    Hello! I am trying to remove the 2 million cards (must have been exceeded and makes the search index rebuild take days) in a single folder in the directory of knowledge on portal 6.1. To delete the folder ('apply later') working half yesterday and then all night with nothing connected to the PTSpy or the joblog, little or no CPU activity.

    Does anyone have a DB query that can zap cards for this crawler? I know how to select the cards for a particular ID on caterpillars, but don't understand how to remove properly such that all references to these maps in other tables are also deleted.

    Much appreciate!

  • How to remove blocks of stamps for a specific object cache

    Hello world

    is it possible to remove the blocks that belogns to a specific object (a table for ex) of the buffer cache.

    as you know, there is
    alter system flush buffer_cache;
    command, but it does a job for all to buffer cache. If you ask me why I want to than this, for reasons of tuning. I want to test some plsql codes when they are run as if they are running for the first time (reading the disc).

    PS: I use oracle 11g r2

    Melody to reduce I/O logic.

    That's all you need. Your willingness to 'scenario' will NEVER materialize in real time conditions, unless you resize the buffer cache to something really small, forcing them to always make each statement of physical i/o.

    This is how Oracle works. Design a database that is more suited to your taste, or learn to live with it.
