Low memory message on Windows 7 SP1

I have a big problem with a computer that is getting a Low memory message. The specifications of this computer are:



  • Windows 7 SP1

  • 32-bit Operating System

  • 4 GB RAM


The computer is getting the following message every 4 or 5 days:


Your computer is low on memory To restore enough memory for programs to work correctly, save your files and then close or restart all open programs.


After this message appears the computer starts to run very slow and we need to restart it. The problem is that the computer it’s in a production environment and has to monitories the activity of a PLC constantly. The actions that we did trying to fix this memory problem but without success are:



  • Stop all the applications that use a high volume of memory (SQL Server, Wonderware InTouch HMI SCADA, Reporting Services, VMWare)

  • Reinstall the operative system and all the software.

  • Scan for a virus issue without success.


Checking the event viewer we found the following suspects messages:



  • Application log


Warning: PerfDisk; Unable to read performance data for the Disk performance counters.



  • System log


Warning: Windows successfully diagnosed a low virtual memory condition. The following programs consumed the most virtual memory: view.exe (4560) consumed 37871616 bytes, DASSIDirect.exe (2904) consumed 21807104 bytes, and perfmon.exe (5868) consumed 18018304 bytes.


Error: The Vstor2 P2V30 Virtual Storage Driver service failed to start due to the following error: The system cannot find the path specified.


Checking the memory used in Resource Monitor window we found that the Commit charge increases constantly till arrives to 100% aprox. And the Memory Modified increase the same way. The Memory in Use stays at the values 1GB aprox.


This Commit charge increase is normal? It doesn’t have to decrease when internal processes are finished

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
