Microsoft is releasing a new cumulative update for the initial Windows 10 version. The patch KB4491101 raises the operating system version to 10240.18135.

The change log includes the following two items.

  • Addresses an issue that may prevent Internet Explorer from loading images that have a backslash (\) in their relative source path.
  • Addresses a reliability issue with win32kfull.sys introduced in KB4487026.

Also, it comes with a list of known issues.

Symptom Workaround
After installing this update, the first character of the Japanese Era name is not recognized as an abbreviation and may cause date parsing issues. Modify the registry with the two- character abbreviation for Japanese Eras as follows:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\Calendars\Japanese\Eras]

"1868 01 01"="明治_明_Meiji_M"

"1912 07 30"="大正_大_Taisho_T"

"1926 12 25"="昭和_昭_Showa_S"

"1989 01 08"="平成_平_Heisei_H"

Microsoft is working on a resolution and will provide an update in an upcoming release.
Applications that use a Microsoft Jet database with the Microsoft Access 95 file format may randomly stop working. For these workarounds, you must install Microsoft Access 2007 or the Microsoft Access 2007 runtime.

Option 1: Convert the database to a newer .mdb file format. This doesn’t require a change to the Connection string.

  1. Use Microsoft Access 2007 or older to open a database that has an older file format.
  2. You will be asked if you would like to convert. Select No to open the database in the current format.
  3. From the Office Button menu, select Save asand select Access 2002-2003 Database.

Option 2: Convert the database to a newer .mdb file format using VBscript. This doesn’t require a change to the Connection string.

  1. Save the following vbscript code to a file such as convert2x3x.vbs and update the database names accordingly.

dim dbe

set dbe = CreateObject("DAO.DBEngine.120")

dbe.CompactDatabase "<my2xdb.mdb>", "<mydb3x.mdb>", , 32

  1. Run the script from a cmd prompt.

C:\myfolder\> \windows\syswow64\cscript convert2x3x.vbs

Option 3: Convert the database to the .accdb file format using VBscript. To use the .accdb file format, you must change the Connection string after conversion.

  1. Save the following vbscript code to a file such as convert2xAce.vbs and update the database names accordingly.

dim dbe

set dbe = CreateObject("DAO.DBEngine.120")

dbe.CompactDatabase "<my2xdb.mdb>", "<mydbACE.accdb>", , 128

  1. Run the script from a cmd prompt.

C:\myfolder\> \windows\syswow64\cscript convert2xAce.vbs

Microsoft is working on a resolution and estimates a solution will be available in March 2019.

To get this update, open Settings - > Update &recovery and click on the Check for Updates button on the right. Alternatively, you can get it from the Windows Update online catalog.
