    There is no switch for windows kernel to disable sse, you need modded kernel, do it yourself :)

    There is no for Windows but it is in Grub2 - WRMSR command I just don't know what registry address to change the bit 26 SSE2:


    I also found a msr-cmd.exe tool for Windows but I don't know how to use it to edit bit 26 SSE2:

            msr-cmd.exe [options] read <reg>
            msr-cmd.exe [options] write <reg> <edx(63~32)> <eax(31~0)>
            msr-cmd.exe [options] -l write <reg> <hex_val(63~0)>
            msr-cmd.exe [options] rmw <reg> <h bit> <l bit> <unmasked_hex_val>
            msr-cmd.exe [options] rmwmask <reg> <mask(63~0)> <unmasked_hex_val>
            msr-cmd.exe [options] getbit <reg> <#bit>
            msr-cmd.exe [options] setbit <reg> <#bit> <0/1>
            -s              write only do not read back
            -d              data only, not to print column item name
            -g <GRP>        processor group (default: 0) to apply
                            'A' or 'a' to apply to all available processors groups
                            by default, a group can contain up to 64 logical processors

    However, I modified another - IA32_CLOCK_MODULATION 0x19A register without any problems in GRUB2:

    wrmsr 0x19a 0x12

    or under WinXP 64-bit with msr-cmd.exe:

    msr-cmd read 0x19a
    msr_read(): CPU 0 reg: 0x0000019a edx: 0x00000000 eax: 0x00000002
    msr-cmd write 0x19a 0x00000000 0x00000012
    msr_write(): ret: CPU 0 reg: 0x0000019a edx: 0x00000000 eax: 0x00000012

  2. I use Pale Moon 28.10.6a1 (64-bit) 20230413

    mega.nz works well only at the first visit. At the following sessions there is a problem with displaying files and only shows an Empty folder


    The same problem is on Win7

    To display files, you need to close the browser, delete the %appdata%\Moonchild Productions folder, start the browser and log in on mega.nz

    1.Install Service Pack 2

    2.Install Office 2007

    3.Uninstall Service Pack 2

    You don't have to install SP2.

    When the value of CSDVersion is default 256 DEC then install error:


    but after changing value of the CSDVersion to 512 DEC and restart instalation goes:

    OMG! It's not about that !!! :angry:

    I want to right-click on a file, select from the context menu, for example, called "Copy to" after which the window selecting target appears and the field in which I can enter the new file name.

    A specific example.

    On the partition D: I have a long name ISO file pl_windows_7_ultimate_with_sp1_x64_dvd_618244.iso

    I want to copy this file immediately to a pendrive in one step under another name win7.iso

    I do not want to copy a file with a long name, later change the name manually!!!

  5. In QEMU (virt-manager) on Linux you have to do this:

    qemu-system-x86_64 -cpu host,-sse2

    In QEMU on Windows:

    qemu-system-x86_64 -cpu qemu64,-sse2

    In the Linux host system, e.g. Debian you need add the option clearcpuid=26 to the kernel cmd line in /etc/default/grub:


    then update-grub and reboot

    To check if it works:

    cat /proc/cpuinfo | grep flags

    How to disable CPU Feature / Flag HLE "Hardware Lock Elision" on RHEL x86 - intel


    #define X86_FEATURE_XMM2 ( 0*32+26) /* "sse2" */

    How to achieve the same for Windows without using a virtual machine?

    I found it: set-sse2-enable but this is a guide on how to compile their own applications so that they do not use SSE2
