The Windows patches for Meltdown and Spectre will slow your PC down. On a newer PC running Windows 10, you probably won’t notice. But, on a PC with an older processor—especially if it’s running Windows 7 or 8—you may see a noticeable slowdown.
You can also disable the protection in the registry yourself, if you like. Run the commands under “To disable this fix” on this Microsoft support page. Restart your PC after changing the registry settings. If you change your mind and want to re-enable the protection in the future, run the instructions under “To enable the fix” on the Microsoft web page.
You can use batch files to enable or disable the fix.
Download
- disable_hotfix_Spectre_and_Meltdown.cmd
- disable_hotfix_Spectre.cmd
- enable_hotfix_Spectre_and_Meltdown.cmd
- enable_hotfix_Spectre.cmd
Execute the required batch file and restart Windows.
Very useful function, but many do not know about its existence.
Solidworks help
Sketch Picture includes the following capabilities:
- Insert pictures (.bmp, .gif, .jpg, .jpeg, .tif, .tiff, .wmf, .png, .psd) on a sketch plane.
- Use pictures as an underlay for creating 2D sketches.
- Convert raster data to vector data using Autotrace.
A sketch picture is inserted with its (0, 0) coordinate at the sketch origin
If you insert a sketch picture of a .tiff file, the resolution is limited to 4096 x 4096. Files that exceed this limit are cut in half until both dimensions meet the limit. For example, if you insert a .tiff file that is 5000 x 3000, the file is reduced to 2500 x 1500.
Autotrace is an add-in that allows you to trace and convert images such as .jpegs and .bitmaps into sketch geometry. This add-in works best with high-contrast images.
- Source image should be hi-resolution, with a minimum of 300dpi.
- Line art should be pen on paper, with precise contours and high contrast.
- Colors should be as uniform as possible within the area you select.
A sketch picture is inserted with its (0, 0) coordinate at the sketch origin:
The second page of the Sketch Picture PropertyManager is only available if Autotrace is enabled as an add-in. Click Tools > Add-Ins and select Autotrace in the dialog box.
Compatibility with Autotrace
- You can use still image formats such as .bmp, .gif, or .jpg, but not animated formats such as animated gif or .avi files.
- You can apply Autotrace to part or assembly files (*.sldprt and *.sldasm), but not to drawing files (*.slddrw).
DS SOLIDWORKS is performing extensive testing in an effort to determine the potential impact of any solutions that are issued to mitigate the Spectre and Meltdown vulnerabilities.
The SOLIDWORKS Knowledgebase solution S-074167 discusses the potential effect on performance upon systems that have employed the Microsoft® Windows® Update security patch released on January 9th, 2018 that was intended to address the Spectre and Meltdown vulnerabilities.
DS SOLIDWORKS intends to report the results of their ongoing tests at SOLIDWORKS World (Feb 4th – 7th 2018). The report will likely be relayed to reseller staff and further updates can be expected by our customers during the second week in February.SOLIDWORKS Knowledgebase solution S-074167
